Abstract:

Pro-insecticides are chemical compounds, the bioactivation of which occurs in the body of insects, where they are transformed into metabolites with greater insecticidal activity. These substances account for 20% of the total amount of insecticides on the market, and they account for 34% of the value of all world sales. Only after many years of use of insecticides did it become known that a significant part of them are precursors. According to the Insecticide Resistance Action Committee (IRAC), about 40% of chemical groups contain precursors that require structural changes to manifest their ins

We investigated that the bioefficacies of cinnamon oil and insecticide based on the mixture of porous starch and cinnamon oil. They were evaluated for their insecticidal activities and their mortality on adults of Sitophilus zeamais. Fumigant toxicity assayed by hanging in glass jars showed that these chemicals caused significant mortality of the test insect. Cinnamon oil evoked high repellent action and high fumigant toxicity (LD50 = 0.030μL/cm3) against adults of Sitophilus zeamais.

Abstract:

Insects occupy fundamental places in the world’s ecosystems. Some insects carry the causative agents of many diseases. The use of synthetic insecticides has been restricted recently, mainly due to harmful environmental effects, and increasing insecticidal resistance. Herbal medicines can possess insecticide effects via many mechanisms. The current review was designed to highlight the medicinal plants with insecticide and insect repellent activities with special focus on their mechanism of action.

Abstract:

Insecticide resistance poses a significant and increasing threat to the control of malaria and other mosquito-borne diseases. We present a novel method of insecticide application based on netting treated with an electrostatic coating that binds insecticidal particles through polarity. Electrostatic netting can hold small amounts of insecticides effectively and results in enhanced bioavailability upon contact by the insect. Six pyrethroid-resistant Anopheles mosquito strains from across Africa were exposed to similar concentrations of deltamethrin on electrostatic netting or a standard long-las

Abstract:

With the passage of time and indiscreet usage of insecticides on crops, aphids are becoming resistant to their effect. The different classes of insecticides, including organophosphates, carbamates, pyrethroids and neonicotinoids, have varied effects on insects. Furthermore, the molecular effects of these insecticides in aphids, including effects on the enzymatic machinery and gene mutation, are resulting in aphid resistance to the insecticides. In this review, we will discuss how aphids are affected by the overuse of pesticides, how resistance appears, and which mechanisms participate in the r

Abstract:

High concentration of insecticides may appear in waters surrounding paddy fields shortly after application. Capturing the dynamic feature of this insecticide pulse may help control insecticide load to receiving waters. Based on continuous monitoring of the drainage process and two monitoring campaigns of three insecticides—chlorpyrifos, abamectin and thiamethoxam—in a paddy, this study examined the pattern of insecticide concentrations at different locations of paddy waters during the period of insecticide application accompanied with pest-control irrigation, and analyzed the factors affecting

Piperonyl butoxide (PBO) used worldwide as a synergist for pyrethroids because it inhibits monooxygenases, the enzyme systems of arthropods that detoxify insecticides. The introduction of PBO into the formulation is most popular for insecticides in aerosol packaging, however, PBO often included in other formulations. The effectiveness of using synergists depends on their content in the product – the more synergist in the mixture, the more pronounced the insecticidal effect. Synergists often proposed as a tool for controlling resistant insects, but arthropods have been shown to very quickly acq

Metabolic detoxification, in which insecticides are metabolized by enzymes, including cytochrome P450s, hydrolases, and glutathione-S-transferases (GSTs), to become more polar and less toxic, is one of the major mechanisms involved in the development of insecticide resistance. Piperonyl butoxide (PBO),S,S,S,-tributylphosphorotrithioate (DEF), and diethyl maleate (DEM) are inhibitors of P450s, hydrolases, and GSTs, respectively, and are frequently used as insecticide synergists in assessing the metabolic mechanisms that may be involved in the detoxification of insecticides and in the developmen

Malaria transmission has been substantially reduced across Africa through the distribution of long-lasting insecticidal nets (LLINs). However, the emergence of insecticide resistance within mosquito vectors risks jeopardizing the future efficacy of this control strategy. The severity of this threat is uncertain because the consequences of resistance for mosquito fitness are poorly understood: while resistant mosquitoes are no longer immediately killed upon contact with LLINs, their transmission potential may be curtailed because of longer-term fitness costs that persist beyond the first 24 h a

As they have limited toxicity to mosquitoes owing to the selection of resistance mechanisms, insecticides may also interact with pathogens developing in mosquitoes.
