This study was conducted in the experimental field of Entomology Division, Bangladesh Agricultural Research Institute (BARI), Gazipur during October 2014 to April 2015 to know the population abundance of leaf-eating caterpillars, namely prodania caterpillar, Spodoptera litura and diamondback moth (DBM), Plutella xylostella attacking cabbage in Bangladesh. The lowest population of both DBM and prodania larvae per plant was found during November and January whereas the highest population per plant was recorded during September and March 2014 and 2015, respectively. The same trend were observed in case of the adult population in the sex pheromone trap catch. The adult prodania caterpillar population was the highest during October-November and March. During December population declined totally in the month of January. The highest diamondback moth (Plutella xylostella) population was observed during November and March. During the last week of December population again declined entirely which continued until the last week of January. S. litura population was always higher than that of diamondback moth (DBM). There is a positive correlation between the rise of temperature with the population buildup of both S. litura and P. xylostella in cabbage. Especially when the mean temperature declined below 15˚C then the population of both the pest became nil.

AbstractThe diamondback moth (DBM) (Plutella xylostella) is one of the main pests of brassicaceous crops worldwide and shows resistance against a wide range of synthetic insecticides incurring millions of dollars in control costs every year. The DBM is a prime example of the introduction of an exotic species as a consequence of globalization. In this study we analyzed the genetic population structure of the DBM and two of its parasitic wasps, Diadegma semiclausum and Diadegma fenestrale, based on mitochondrial DNA sequences. We analyzed DBM samples from 13 regions worldwide (n = 278), and samples of the two wasp species from six European and African countries (n = 131), in an attempt to reconstruct the geographic origin and phylogeography of the DBM and its two parasitic wasps. We found high variability in COI sequences in the diamondback moth. Haplotype analysis showed three distinct genetic clusters, one of which could represent a cryptic species. Mismatch analysis confirmed the hypothesized recent spread of diamondback moths in North America, Australia and New Zealand. The highest genetic variability was found in African DBM samples. Our data corroborate prior claims of Africa as the most probable origin of the species but cannot preclude Asia as an alternative. No genetic variability was found in the two Diadegma species. The lack of variability in both wasp species suggests a very recent spread of bottlenecked populations, possibly facilitated by their use as biocontrol agents. Our data thus also contain no signals of host-parasitoid co-evolution.

The diamondback moth (DBM),Plutella xylostella(L.) (Lepidoptera: Plutellidae), is a major pest of Brassicaceae family in Iran. This study investigated the sublethal effects of pyriproxyfen, a juvenile hormone analogue, on DBM, for two subsequent generations. The leaf dip bioassay method was adopted in conducting this experiment. Sublethal concentrations resulted in a significant decrease in fecundity, oviposition period, and pupal weight of parents and offspring generations. Also, the development time of DBM was prolonged after exposure to pyriproxyfen. The biological parameters such as net reproductive rate (R0) and intrinsic (rm) and finite (λ) rate of increase were lower than control in treatment groups, significantly. From our investigations, pyriproxyfen is a good choice for control of the diamondback moth population through continuous generations.

Inbreds and hybrid cabbage (Brassica oleracea var. capitata) selected for resistance to diamondback moth (DBM, Plutella xylostella L.) were tested in the field in New York and Honduras for resistance. In New York, plants were inocrdated with up to 400 eggs per plant to enhance the severity of the tests. In Honduras, where natural populations of DBM were high, especially in the dry season, there were three distinct classes of susceptibility to DBM: the very susceptible controls or standard cultivars, the highly resistant glossy-leaved lines, and the intermediate selections with normal leaf bloom. Some normal-leaf hybrids were more resistant than either of their parents, which indicates the need to select for specific combining ability for high resistance levels. At maturity, the glossy-leaved hybrids produced marketable crops with: out aid of chemical sprays.

Full textAbstract:
The ecology of diamondback moth (DBM), Plutella xylsotella L. (Lepidoptera: Plutellidae), and records of its frequent, but sporadic, population outbreaks in the canola agroecosystems of southern and western Australia are reviewed. The migratory capacity of DBM, possible maintenance of pest populations on brassicaceous weeds and forage crops, resistance to commonly used pyrethroid insecticides, a lack of effective natural enemies (due to disruption by insecticides and difficulties associated with colonising the vast areas of canola crops) and suitable climatic conditions during critical phases of the crop cycle are all likely to contribute to the observed pest outbreaks. A greater understanding of the ecology of DBM in the canola landscape is fundamental to improving its management in the crop but relevant long-term DBM abundance data are currently lacking. Five critical research issues are identified: (i) improved understanding of the factors which determine regional movement patterns of diamondback in canola-growing areas; (ii) the development and implementation of flexible insecticide resistance management strategies; (iii) better understanding of canola crop colonisation by natural enemies of DBM and their population dynamics under current and alternative insecticide application strategies; (iv) greater appreciation of the interactions between DBM and its crop and weedy host plants; and (v) the development of validated simulation models to aid in the forecasting of possible DBM outbreaks. Each issue represents a significant challenge but all must be addressed if the development of a sustainable integrated strategy for the management of DBM in Australian canola is to become a reality.

Effect of Intercropping White Cabbage with French Marigold (Tagetes Patula Nana) and Pot Marigold (Calendula Officinalis) on Diamondback Moth (Plutella XylostellaL.) Population Density and it's Parasitoid ComplexThe impact of intercropping white cabbage (‘Bently F1’) with French MarigoldTagetes patula nana‘Kolombina’ and Pot MarigoldCalendula officinalis‘Promyk’ on the occurrence of diamondback moth (DBM) (Plutella xylostellaL.) and its parasitoid complex was estimated in years 2003-2005. The number of DBM larvae and pupae was significantly lower on plots where cabbage was intercropped compared with the control variant (homogenous crop). The combination with Pot Marigold turned out to be the best in this respect. The DBM larvae parasitization level varied from year to year and its percentage oscillated from 65 to 88%. Eight beneficial insect species belonging to families:Ichneumonidae(4 species),Braconidae(2 species),Pteromalidae(1 species) andEulophidae(1 species) emerged from collected DBM pupae.Diadegma fenestralisHolmgr. was the most abundant species among allPlutellaparasitoids every year of observations as it constitued 65% of all of the reared wasps. No significant differences were determined between the level of parasitization in relation to the type of cultivation.

The diamondback moth (DBM) is a destructive pest of crucifer crops. In this study, DBM larvae shown to herbivore induced plant volatiles (HIPVs) that were attractive to adult females exposed in a Y-tube olfactometer. Our results showed that olfactory responses of adult females to HIPVs induced by third instar larvae feeding on Barbarea vulgaris were significantly higher (20.40 ± 1.78; mean moths (%) ± SD) than those induced by first instar larvae (14.80 ± 1.86; mean moths (%) ± SD). Meanwhile, a significant concentration of Sulphur-containing isothiocyanate, 3-methylsulfinylpropyl isothiocyanate, and 4-methylsulfinyl-3-butenyl isothiocyanate were detected in HIPVs released by third instar larvae compared to those released by first instar larvae while feeding on B. vulgaris. When the DBM females were exposed to synthetic chemicals, singly and in blend form, a similar response was observed as to natural HIPVs. Our study demonstrated that the relationship between isothiocyanates acting as plant defense compounds, host plant cues emission and regulation of the DBM adult female behavior due to key volatile triggered by the DBM larvae feeding on B. vulgaris.

AbstractThe diamondback moth (DBM, Plutella xylostella L. (Lepidoptera: Plutellidae)) consumes a wide variety of brassicaceous host plants and is a common pest of crucifer crops worldwide. A highly unusual infestation of a sugar pea crop was recorded in Kenya in 1999, which persisted for two consecutive years. A strain (DBM-P) from this population was established in the laboratory and is the only one of several strains tested that can complete larval development on sugar peas. The oviposition acceptance and preference of the DBM-P strain was assessed in the presence of cabbage plants, sugar pea plants or both, in comparison to another strain (DBM-Cj) that was collected from cabbage and is unable to grow on pea plants. As expected, DBM-Cj females preferred to oviposit on cabbage plants. Surprisingly, DBM-P females also laid most eggs on cabbage and very few on peas. However, they laid significantly more eggs on the cabbage plant when pea plants were present. Our findings suggest that DBM-P manifested the initial stages of an evolutionary host range expansion, which is incomplete due to lack of oviposition fidelity on pea plants.

Orientador: Sergio Antonio de Bortoli<br>Resumo: O cultivo intensivo de Brassicaceae favorece o aparecimento de algumas pragas como Plutella xylostella (Linnaeus, 1758) (Lepidoptera: Plutellidae), a traça-das-crucíferas, cujos danos podem comprometer seriamente a produção. Esse inseto-praga pode ser controlado tanto com inseticidas sintéticos, como com biológicos, sendo, no entanto, usualmente utilizados os sintéticos em seu combate. A traça-das-crucíferas foi a primeira espécie de inseto a ser constatada resistência a inseticidas biológicos, com o uso indiscriminado de inseticidas sintéticos para o seu controle contribuindo também para a seleção de indivíduos tolerantes ou resistentes, além de causar a mortalidade de organismos não alvos. Sendo assim, este trabalho teve por objetivo avaliar a atividade inseticida e os efeitos subletais de duas toxinas lepidóptero-ativas de Bacillus thuringiensis, Cry1Ca e Cry2Ac, em três populações de traças-das-crucíferas, sendo uma delas suscetível (PC) e duas consideradas resistentes (Bt e NO-QA) a toxinas de B. thuringienis, em condições de laboratório. Foram realizados bioensaios de suscetibilidade com as três populações e as toxinas Cry1Ca e Cry2Ac, estimando-se a concentração letal (CL50) e os seus efeitos subletais. A toxina Cry2Ac não causou mortalidade nas lagartas das três populações, então os testes subletais foram realizados apenas com a toxina Cry1Ca que provocou mortalidade. Os parâmetros biológicos avaliados foram: período e peso pupal, sobrevivência larval e pupal, longevi...

This insect-pest can be controlled either synthetic insecticides as biological insecticides, but synthetics are usually used to combat. Diamondback moth was the first insect species to be verified resistance to biological insecticides, with indiscriminate use of synthetic insecticides for its control, also contributing to selection of tolerant or resistant individuals, as well as causing mortality on non-target organisms. Therefore, the objective of this work was to evaluate insecticide activity and sublethal effects of two lepidopteran-active toxins of Bacillus thuringiensis, Cry1Ca and Cry2Ac, on three DBM populations, one of them susceptible (PC) and two considered as resistant (Bt and NO-QA) to B. thuringiens toxins under laboratory conditions. Susceptibility bioassays were performed on the three populations and toxins Cry1Ca and Cry2Ac, estimating lethal concentration (LC50) and its sublethal effects. Cry2Ac toxin did not cause mortality on the caterpillars from the three populations, so the sublethal tests were performed only with Cry1Ca toxin. The biological parameters evaluated were: pupal period and weight, caterpillar and pupal survival, male and female longevity and fecundity. The populations showed susceptibilities to Cry1Ca toxin, with statistically equal behavio... (Complete abstract click electronic access below)<br>Mestre
