Abstract:
A highly efficient lambda-cyhalothrin-degrading bacterium, designated as strain ZC-5, was isolated from the activated sludge of a sewage aeration tank in a pesticide factory by enrichment acclimation and the streak plate method. Strain ZC-5 can grow on minimal medium with lambda-cyhalothrin as the sole source of carbon and nitrogen. After cultivation for 6 h to 24 h, the biomass of the bacterial strain significantly increased at the logarithmic phase. By contrast, the concentration of lambda-cyhalothrin rapidly decreased. The residual lambda-cyhalothrin presented a concentration of 250 mg/L and a degradation rate of 50%. Gas chromatography revealed that this strain can degrade 87.1% lambda-cyhalothrin (500 mg/L) in the culture within 2 days. Morphological analysis showed the Gram-negative strain as short rods. Physiological and biochemical characterizations, as well as phylogenetic analysis of the 16S rDNA sequence identified the bacterium to be an Achromobacter xylosoxidans strain. Results showed that this strain can provide a novel strategy to biodegrade the pesticide lambda-cyhalothrin.

Abstract:
This work presents laboratory studies on the degradation of lambda-cyhalothrin. At first, a rapid quantitative determination method of lambda-cyhalothrin in food was developed by high performance liquid chromatography. Lambda-cyhalothrin-degrading bacterium F37 was isolated from the sewage of a pesticide factory outlet and was identified as Citrobacter braakii. The effects of environmental factors including carbon and nitrogen sources, initial pH, medium volume, incubating temperature and substrate concentration on the degradation rate were investigated. The addition of sucrose and yeast extract at the concentrations of 4.0 and 3.0 g/L, respectively, was the best for the degradation of lambda-cyhalothrin. F37 showed higher degradation activity at the range of moderate pH value (pH 6.5-8.0). After 72-h stirring culture, the degradation rates of lambda-cyhalothrin reached 81.1% at pH 7.0. The degradation dynamics analysis showed that the degradation half-life times of lambda-cyhalothrin in the culture liquid of F37 were only 5.7, 1.9 and 4.9 days at pH 9.0, 7.0 and 5.0, respectively. In addition, cypermethrin and triazophos could also be degraded by F37, showing that F37 was a broad-spectrum pesticide- degrading bacterium. Application of F37 on eliminating pesticide in vegetable showed that 68% of lambda-cyhalothrin was removed after treatment for 48 h. The results indicated that Citrobacter braakii F37 is effective in the elimination of pesticide and may provide a potent application in detergent industry and environmental restoration.

Abstract:
Toxic stress caused by pesticides changes the function and structure of the aquatic ecosystem via impressing to species composition. Therefore it is necessary to determine the reaction of cyanobacteria to pesticides for comprehend the effects of these substances on the aquatic ecosystems. This study aims to determine the toxicity and oxidative stress that Lambda cyhalothrin may cause in cyanobacteria, one of the primary producers in lake ecosystems. For these reasons, the changes in chlorophyll-a content, OD560 absorbance, the antioxidant enzyme acitvities such as superoxidedismutase (SOD), ascorbate peroxidase (APX), and glutathione reducatse (GR) were assessed to carry out the effect of Lambda cyhalothrin concentrations (between 6.25 and 100 μg ml−1) on Arthrospira platensis. EC50 value is calculated as 11.94 μg m l−1 Lambda cyhalothrin concentrations. SOD and APX activities was statistically different from the control at 100 μg m l−1 Lambda cyhalothrin application compared to control in A. platensis-M2 cells. On the other hand, GR activity did not effect significantly. According to our results, we may conclude that Lambda cyhalothrin concentrations used in this study inhibited the growth of A. platensis cells in a time and dose-dependent manner, as indicated by lowered chlorophyll-a content and OD560 values and Lambda cyhalothrin caused oxidative stress in A. platensis cells. As a result, the restriction of Lambda cyhalothrin using at the certain concentrations may be a step to prevent pesticide pollution in the environment.

Abstract:
Nanotechnology could greatly improve global agricultural food production. Chlorantraniliprole and lambda cyhalothrin double-loaded nano-microcapsules were fabricated to enhance the control of pests by pesticides and improve the pesticide utilization efficiency. The nano-microcapsules were synthesized using a method involving the solid in oil in water encapsulation technique and solvent evaporation. The nano-microcapsules slowly and simultaneously released lambda cyhalothrin and chlorantraniliprole. The cumulative lambda cyhalothrin and chlorantraniliprole release rates at 40 h were 80% and 70%, respectively. Indoor Spodoptera frugiperda control tests indicated that the double-loaded nano-microcapsules were more toxic than lambda cyhalothrin water-dispersible granules, chlorantraniliprole water-dispersible granules, and a mixture of lambda cyhalothrin water-dispersible granules and chlorantraniliprole water-dispersible granules, indicating that the pesticides in the nano-microcapsules synergistically controlled Spodoptera frugiperda. The results indicated that pesticide nano-microcapsules with synergistic effects can be developed that can improve the effective pesticide utilization efficiency and pesticide bioavailability. This is a new idea for achieving environmentally intelligent pesticide delivery.

Abstract:
Taurine is a major intracellular free β-amino acid, which can protect the body against toxicity. Lambda-cyhalothrin, a third-generation type II pyrethroid. is used predominantly in agriculture production and animal husbandry. The aim of the present study was to investigate lambda cyhalothrin-induced biochemical changes in rat liver and to search out the possible role of taurine for the attenuation of hepatotoxic biomarkers. Male rats were randomly divided into six groups and lambda cyhalothrin was orally administered at two dose levels (10.83mg/body wt., 15.17mg/body wt.) alone and in combination with taurine pretreatment (50mg/kg body wt) for 14 consecutive days. A significant change in blood glucose level with a marked decline in glycogen content were indicated the hepatic dysfunction in lambda cyhalothrin treated rats. This was also confirmed by the altered activities of serum hepatic biomarker enzymes and lipid profiles in LCT intoxicated rats. Pre-treatment of taurine mitigated the abnormalities. These findings pointed out the toxic effect of lambda cyhalothrin in rat liver and also revealed the protective action of taurine against this pyrethroid.

Abstract:
The novel ingestion bioassay method was developed for detecting and monitoring resistance of Euschistus heros by encapsulating an artificial liquid diet using Parafilm®. This methodology was compared with the tarsal contact (vial test) and topical application methods for thiamethoxam, imidacloprid, and lambda-cyhalothrin. The best bioassay method for the neonicotinoid insecticides thiamethoxam and imidacloprid was ingestion. For pyrethroid insecticide lambda-cyhalothrin, the best result was obtained by topical application. Using the best bioassay method for each insecticide, the susceptibility to these insecticides was monitored in 30 populations of E. heros collected from soybean crops in Brazil from 2018 to 2020. High variations in susceptibility to thiamethoxam (resistance ratios, 1.6–22 times), imidacloprid (resistance ratios, 1.6–22 times), and lambda-cyhalothrin (resistance ratios, 5–40 times) were detected among the evaluated E. heros populations. In order to monitor the susceptibility of E. heros to insecticides, diagnostic concentrations were defined based on the LC99 of the susceptible reference population: 5.65 µL of a.i./mL for thiamethoxam, 12.45 µL of a.i./mL for imidacloprid, and 0.20 µg of a.i./insect for lambda-cyhalothrin. Subsequently, we select an E. heros strain resistant to neonicotinoid insecticides and another to lambda-cyhalothrin. The resistance ratios obtained after seven selection cycles were 66, 41 and 44 times for thiamethoxam, imidacloprid and lambda-cyhalothrin, respectively.

Abstract:
Indoor residual house spraying using lambda-cyhalothrin, deltamethrin and dichlorodiphenyltrichloroethane (DDT) was conducted in Zhombe Resettlement area, Zimbabwe. A total of 204/219 (93.1%), 224/260 (86.2%) and 257/325 (79.1%) rooms were sprayed with lambda-cyhalothrin, deltamethrin and DDT wettable powders respectively. Bioassays were conducted on sprayed walls and roofs using 3-5 day old laboratory reared susceptible <em>Anopheles gambiae sensu lato </em>mosquitoes placed in World Health Organization cones. <br />Bioassays conducted on sprayed walls (1 month), showed that efficacy of lambda-cyhalothrin was the same with DDT but different with deltamethrin and this trend continued in the 2<sup>nd</sup> month. During the 3rd month, lambda-cyhalothrin killed more mosquitoes than deltamethrin (P=1.931x10<sup>-14</sup>), DDT killed more mosquitoes than deltamethrin (P=0.0001) and lambda-cyhalothrin killed more mosquitoes than DDT (walls). Efficacy of lambda-cyhalothrin and DDT was the same 4 months post spray (P=0.487), notable differences were seen in lambdacyhalothrin and deltamethrin (P=2.57x10<sup>-6</sup>), DDT and deltamethrin (P=2.17-10<sup>-8</sup>). Efficacy of lambda-cyhalothrin and DDT was the same 5 months post spray (P=0.244), major differences were found in lambdacyhalothrin and deltamethrin (P=0.000), DDT and deltamethrin (P=5.18x10<sup>-5</sup>) and this trend continued in the 6<sup>th</sup> month. One month after spraying roofs, mortality of mosquitoes due to lambdacyhalothrin/ deltamethrin (P=2.56x10<sup>-5</sup>), lambda-cyhalothrin/DDT (P=1.2x10<sup>-7</sup>) and deltamethrin/DDT (P=0.013) were significantly different and this continued in the 2<sup>nd</sup> month. However, 3 months after spraying, mortality due to lambda-cyhalothrin/deltamethrin (P=1.46x10<sup>-6</sup>), lambda-cyhalothrin/DDT (P=0.048), and deltamethrin/DDT (P=0.004) were significantly different and this continued in the 4<sup>th</sup> month. Five months after spraying roofs, mortality due to lambda-cyhalothrin/ deltamethrin (P=0.000) and deltamethrin/DDT (P=6.6x10<sup>-7</sup>) were significantly different. Six months after spraying, lambdacyhalothrin/ deltamethrin (P=0.34), lambda-cyhalothrin/DDT (P=0.982), and deltamethrin/DDT (P=0.64) were not significantly different. When using exit window traps, no mosquitoes were collected from rooms sprayed with each of the insecticides over a 6-month period. However, 17, 6, 14, 7, 2 and 3 fed <em>An. gambiae sl </em>mosquitoes were collected in the 1<sup>st</sup>, 2<sup>nd</sup>, 3<sup>rd</sup>, 4<sup>th</sup>, 5<sup>th</sup> and 6<sup>th</sup> month respectively from unsprayed rooms and none of them died after 24 h.

Abstract:
The experiment was accomplished to evaluate the bioefficacy of different insecticides against Mylabris phalerata (Pallas) on pigeonpea. The experiment consisted of seven treatments viz., bifenthrin 62 g a.i. ha-1, lambda-cyhalothrin 24 g a.i. ha-1 (encapsulated with polymers; Matadore), chlorpyriphos 310 g a.i. ha-1+ cypermethrin 31 g a.i. ha-1, cypermethrin 62 g a.i. ha-1, neem oil 1500 ppm, permethrin 154 g a.i. ha-1, chloropyriphos 173 g a.i. ha-1 compared with untreated (control). The sixth day after each spray, minimum population abundance of M. phalerata and maximum percent efficacy in reducing their population was obtained from bifenthrin which was at par with lambda-cyhalothrin, cypermethrin, chlorpyriphos+ cypermethrin and permethrin and all these were significantly effective over chloropyriphos, neem oil and control plots. On the tenth day after each spray, minimum population abundance and highest per cent efficacy were obtained from bifenthrin which was at par with lambda-cyhalothrin and both these treatments were significantly superior over rest of the treatments. The maximum productivity was observed with bifenthrin, while highest net return per rupee investment was obtained from lambda-cyhalothrin treatment. The results explicitly show that out of all treatments, Lambda-cyhalothrin was effective and imposing lucrative against M. phalerata and thereby minimized the yield loss. Three sprays of lambda-cyhalothrin and bifenthrin with an interchange at ten days interval will be effectual and lucrative against M. phalerata in short duration pigeonpea crop.SAARC J.

The objective of this study is to evaluate the antioxidant and hepatoprotective activity of aerial part and seeds of Coriandrum sativum plant against Lambda cyhalothrin insecticide. Male Wistar Albinos rats were randomly divided into control, LCT, CsA, CsS, CsS+LCT, CsA+LCT groups, after 90 days of treatments Biochemical, some oxidative stress parameters, and histopathology of liver tissue were evaluated. Total polyphenol content in aerial part and the seed extract estimated at 9.29 and 14.64 mg EAG / mg of extract and IC50 for an antioxidant activity equal to 19.38 and 22.62 mg/ml respectively. The obtained results revealed that rats received Lambda cyhalothrin insecticide showed a significant change in enzymes activity (AST, ALT, ALP and c-GT) and Glutathione (GSH) in liver. Meanwhile content of hepatic Malondialdehyde (MDA). Histopathology examination of liver revealed that Coriandrum sativum attenuate the incidence of liver lesions triggered by Lambda cyhalothrin intoxication. Therefore, the results of this study show that Coriandrum sativum can be proposed to protect the liver against Lambda cyhalothrin induced oxidative damage in rats, and the hepatoprotective effect might be correlated with its antioxidant and free radical scavenging effect.

Abstract:
Helicoverpa armigera is a polyphagous pest. Due to excessive use of insecticides, the field populations of H. armigera have become resistant to synthetic pyrethroids by one or combination of three mechanisms
reduced penetration through the cuticle, decreased nerve sensitivity and enhanced metabolism by the detoxification enzymes especially glutathione S-transferases. In this study, gut sections of H. armigera were obtained from Adana and Antalya field populations and susceptible populations from Israel. Each gut section was homogenized separately in 1.0 ml, 40 mM and pH 7.5 phosphate buffers. GST activity was determined using CDNB as substrate. Product formation linearly increased up to 29.5µ

Abstract:
Os custos adaptativos associados à resistência de insetos a inseticidas podem ser explorados mediante a integração com outras estratégias de controle de pragas em programas de Manejo Integrado de Pragas (MIP). No presente estudo, objetivou-se verificar custos adaptativos associados à resistência de Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) ao inseticida piretroide lambda-cyhalothrin e suas implicações na utilização do hospedeiro pelo parasitoide larval Campoletis aff. flavicincta (Hymenoptera: Ichneumonidae) e as interações com milho geneticamente modificado (MON810) que expressa a proteína Cry1Ab de Bacillus thuringiensis Berliner (milho Bt) e na resposta imunológica ao parasitismo por Campoletis aff. flavicincta. Foram verificados presença de custos adaptativos associados à resistência de S. frugiperda a lambda-cyhalothrin, dado o prolongamento no desenvolvimento larval e duração pupal, redução do peso de pupas fêmeas e longevidade das fêmeas, razão sexual, taxa líquida de reprodução (Ro), taxa intrínseca de aumento (rm) e taxa finita de aumento () de insetos resistentes ao inseticida. Não foi verificada diferença na aceitação de lagartas de S. frugiperda suscetível e resistente a lambda-cyhalothrin por Campoletis aff. flavicincta. Entretanto, o parasitismo de lagartas resistentes foi maior que de suscetíveis em estudos de gaiolas com milho Bt e não-Bt. Posteriormente, foram conduzidos estudos para avaliar, por PCR em tempo real, a expressão diferencial de genes associados ao metabolismo (proteína rica em metionina), resposta imunológica (calreticulina, lisozima, colágeno IV-2, hemócito protease-3, serina protease, imunolectina, receptor scavenger classe C) e detoxificação de xenobióticos (glutationa-S-transferase 145 e as monoxigenases P450 Cyp9A31 e Cyp333B2) expressos em diferentes tecidos (tecido adiposo, hemócitos e/ou mesêntero), na ausência e presença de parasitismo de lagartas das duas linhagens de S. frugiperda por Campoletis aff. flavicincta. No geral, a expressão gênica em lagartas suscetíveis foi superior àquela de lagartas resistentes a lambda-cyhalothrin, independente do período de desenvolvimento, do tecido avaliado e da presença ou não do parasitismo por Campoletis aff. flavicincta. E por fim, foram conduzidos estudos para avaliar o efeito da resistência de S. frugiperda a lambda-cyhalothrin nas respostas imunológica celular (contagem total de hemócitos) e humoral (atividade das fenoloxidases, lisozimática e antimicrobiana e concentração de óxido nítrico) de lagartas, tanto na ausência como na presença do parasitismo por Campoletis aff. flavicincta. A resistência de S. frugiperda a lambda-cyhalothrin induziu somente a pequenas alterações no sistema imunológico do hospedeiro (aumento do número total de hemócitos, redução da atividade antimicrobiana e aumento da atividade lisozimática), as quais não interferem a ponto de resultar em custos adaptativos que leve à maior exploração de lagartas resistentes na presença do parasitismo por Campoletis aff. flavicincta. Portanto, o manejo de S. frugiperda mediante o emprego da tecnologia de milho Bt e do controle biológico via parasitoide Campoletis aff. flavicincta pode favorecer o restabelecimento da suscetibilidade de S. frugiperda a lambda-cyhalothrin.
Fitness costs of insect resistance to insecticides can be exploited by integrating other pest control strategies in Integrated Pest Management (IPM) programs. The objective of this research was to evaluate the existence of fitness costs associated with the resistance of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) to the pyrethroid insecticide lambda-cyhalothrin and their implications for host use by the larval parasitoid Campoletis aff. flavicincta (Hymenoptera: Ichneumonidae) and interactions with the genetically modified maize (MON810) that expresses Cry1Ab toxin of Bacillus thuringiensis Berliner (Bt maize) and in the immune response to parasitization by Campoletis aff. flavicincta. Fitness costs associated to resistance of S. frugiperda to lambda-cyhalothrin were detected by the delay in larval and pupal development, reduction in the pupal weight and longevity of females, sex ratio, net reproductive rate (Ro), intrinsic rate of natural increase (rm) and the finite rate of increase (). No differences were detected in host acceptance and survival of Campoletis aff. flavicincta in susceptible and lambda-cyhalothrin-resistant larvae of S. frugiperda. However, larval parasitization was higher on the resistant than on the susceptible strain of S. frugiperda in cage studies with Bt and non-Bt maize plants. Then, studies were conducted by using Real time-PCR to evaluate the differential expression of genes associated with metabolism (methionine-rich protein), immune response (calreticulin, lysozyme, collagen IV-2, protease-3 hemocyte, serine protease, immunolectin, scavenger receptor class C) and xenobiotic detoxification (glutathione-S-transferase 145 and P450 monooxygenases Cyp9A31 and Cyp333B2) expressed in different tissues (fat body, hemocytes and/or midgut), in the absence and presence of larval parasitization of both strains of S. frugiperda by Campoletis aff. flavicincta. Overall, gene expression in susceptible larvae was higher than that of lambdacyhalothrin- resistant larvae, regardless of the period of development, tissue evaluated and presence or not of parasitization by Campoletis aff. flavicincta. Finally, studies were conducted to evaluate the effect of the resistance of S. frugiperda to lambda-cyhalothrin on cellular (total hemocyte count) and humoral (phenoloxidases, lysozyme and antimicrobial activities and nitric oxide concentration) immune responses in the absence or presence of parasitization by Campoletis aff. flavicincta. The resistance of S. frugiperda to lambdacyhalothrin conferred only minor changes in the host immune system (increased total hemocyte count, reduced antimicrobial activity and increased lysozyme activity), which may not interfere with fitness costs leading to higher exploitation of resistant larvae in the presence of parasitization by Campoletis aff. flavicincta. Therefore, the management of S. frugiperda by using the Bt maize technology and the biological control via parasitoid Campoletis aff. flavicincta can favor the resetting to susceptibility of S. frugiperda to lambda-cyhalothrin.

Abstract:
Despite advances in mosquito management, mosquito-borne disease in the United States is still of relevant public health concern and vector control is a top priority in preventing transmission of pathogens. Insecticide barrier sprays have become a common tool for suppression of mosquitoes in single-homeowner backyards. The application of the synthetic pyrethroid, lambda-cyhalothrin to perimeter vegetation with a backpack sprayer has been shown to significantly suppress mosquito levels for around 6 weeks. In an attempt to lengthen the effective duration of treatment, the IGR, pyriproxyfen, was added to a backpack mist blower with lambda-cyhalothrin, as adult mosquitoes exposed to pyriproxyfen have been shown to disseminate it to oviposition sites and to experience lowered fecundity. This treatment was compared to lambda-cyhalothrin alone and to a water control. Mosquito populations were sampled using CO2-baited CDC light traps, CDC gravid traps, human landing rates, and ovitraps. Leaf bioassays were performed. The following summer, the same treatments were applied with a truck-mounted mist blower to tree lines in Central Kentucky, to test the efficacy of an application method that could be used on large properties. Finally, bioassays were performed with water sampled from pyriproxyfen-treated containers, exposed to field conditions to test for residual efficacy.
