Resumo -O objetivo deste trabalho foi avaliar a capacidade do caulim de afetar a oviposição e a alimentação de Alabama argillacea (Lepidoptera: Noctuidae) em algodoeiro. Determinou-se a preferência de oviposição, a viabilidade de ovos e o consumo das lagartas de primeiro instar de A. argillacea, em folhas de algodão tratadas ou não com caulim. A preferência de oviposição foi determinada por teste de escolha e confinamento, em delineamento experimental de blocos ao acaso, em arranjo fatorial 2x7, representado pelos tratamentos com caulim em água destilada (60 g L -1 ) ou somente água destilada (testemunha), e pela avaliação de sete estruturas vegetais da planta. O consumo pelas lagartas de primeiro instar foi determinado em delineamento experimental inteiramente casualizado, em arranjo fatorial 2x4, representado pelo tratamento com caulim em água destilada, pela testemunha e pelos quatro períodos de observação (6, 12, 24 e 48 horas). A oviposição das mariposas do curuquerê-do-algodoeiro foi reduzida nas plantas de algodão tratadas com caulim; no entanto, a viabilidade dos ovos não foi afetada. A folha da haste foi a estrutura preferida para oviposição. A sobrevivência e o consumo de lagartas de primeiro instar do curuquerê são menores nas plantas de algodão tratadas com caulim.Termos para indexação: Alabama argillacea, Gossypium hirsutum, filme de partículas, herbivoria. Oviposition of leafworm and feeding of its neonate larvae on cotton treated with kaolinAbstract -The objective of this work was to evaluate the ability of kaolin to affect oviposition and feeding of Alabama argillacea (Lepidoptera: Noctuidae) on cotton. The oviposition preference, the egg viability, and the feed consumption of the first instar larvae of A. argillacea were determined on cotton leaves treated or not with kaolin. The oviposition preference was determined under choice test and confinement, in a randomized complete block design, in a 2x7 factorial arrangement, represented by the treatments with kaolin in distilled water (60 g L -1 ) or distilled water only (control), and by the evaluation of seven plant structures. The feed consumption by the first instar larvae was determined in a completely randomized design, in a 2x4 factorial arrangement, represented by the treatment with kaolin in distilled water, by the control, and by the four observation periods (6, 12, 24, and 48 hours). The oviposition of cotton leafworm moths was reduced in cotton plants treated with kaolin; however, the viability of eggs was not affected. Leaf stem was the preferred structure for oviposition. Survival and feed consumption of first instar larvae of cotton leafworm are lower on cotton plants treated with kaolin.

“…The higher JH concentration together with the lower ecdysteroid concentration may favour longer larval development and a higher number of larval moults, and may allow some developed larvae to recover from ingestion of the Bt-toxin, and to pupate and produce viable adults. The findings reported by Pérez-Hedo et al (2011) will be useful in evaluating the efficacy of seed blends for Btmaize and MCB as refuge strategy for managing MCB resistance in Bt-maize (see also Prasifka et al, 2010, above).- Razze et al (2011) assessed the feeding behaviour of neonate ECB on maize MON 810 and a conventional (near-isogenic) counterpart (Pioneer 33D31) during the first 48 hours after egg eclosion. Feeding experiments revealed that there was significantly less feeding on Bt-maize compared with non-Bt-maize.…”

Following a request from the European Commission, the Panel on Genetically Modified Organisms of the European Food Safety Authority (EFSA GMO Panel) compiled its previous risk assessment conclusions and risk management recommendations on the genetically modified insect resistant maize MON 810, and considered their validity in the light of new relevant scientific publications published from 2009 onwards. Following a search of the scientific literature published between 2009 and October 2012, the EFSA GMO Panel identified 165 peer-reviewed publications containing evidence specific to the risk assessment and/or management of maize MON 810, of which 68 publications were discussed and/or cited in previous EFSA GMO Panel scientific outputs. From the remaining 97 publications, eight were relevant for the molecular characterisation, 27 for food and feed safety assessment, 55 for the environmental risk assessment and/or risk management, two for the molecular characterisation and the environmental risk assessment and/or risk management and five for the food and feed safety assessment and the environmental risk assessment and/or risk management of maize MON 810. None of these publications reported new information that would invalidate the previous conclusions on the safety of maize MON 810 made by the EFSA GMO Panel. Therefore, the EFSA GMO Panel considers that its previous risk assessment conclusions on maize MON 810, as well as its previous recommendations on risk mitigation measures and monitoring, remain valid and applicable.

“…Overall, these responses to selection, combined with our gene expression data, suggest that the behavioral trait for plant abandonment is likely to be under genetic control and that the genes foraging and Onslmo are involved. Although other studies have described O. nubilalis behavior on transgenic and nontransgenic plants (Ross and Ostlie 1990, Davis and Coleman 1997, Goldstein et al 2010, Razze et al 2011, Razze and Mason 2012, this is the Þrst study that has speciÞcally selected for these traits over several generations and analyzed behavior genes to elucidate genetic changes.…”

“…Genes inßuencing plant abandonment behavior, such as foraging and slowmo, would likely be involved in this process. Other studies have shown neonates disperse more from Bt versus non-Bt plants (Ross and Ostlie 1990, Davis and Coleman 1997, Goldstein et al 2010, Razze et al 2011, Razze and Mason 2012.…”

On-Plant Selection and Genetic Analysis of European Corn Borer (Lepidoptera: Crambidae) Behavioral Traits: Plant Abandonment Versus Plant Establishment

Although some studies have investigated how insect behavior could influence resistance evolution to transgenic plants, none have determined if behavioral traits respond to selection pressure and how they may be inherited. We investigated plant establishment and abandonment traits for the European corn borer, Ostrinia nubilalisi (Hübner) (Lepidoptera: Crambidae), by conducting a laboratory selection experiment and quantifying patterns of gene expression. Egg masses with emerging larvae were placed on maize plants and silking individuals were collected every 15 min during a 4-h period to generate a plant abandonment (PA) colony. Plants were dissected 24-72 h later, and larvae were collected for a plant establishment colony. Selection of the PA colony showed an increased propensity to abandon the host plant by the third generation. The propensity for larvae to establish on the plants, however, did not show a significant response until the sixth generation. Quantitative real-time-polymerase chain reaction (qRT-PCR) was used to determine expression profiles for behavior associated genes (foraging and Onslmo). Egg samples from the two selected colonies and nonselected laboratory colony were collected at 0, 24, 48, 72, and 96 h after egg deposition, and first instars were sampled after exposure to maize tissue. Compared with the plant establishment and nonselected laboratory colonies at the 0-h time period, foraging and Onslmoshowed higher expression in the PA colony. This is the first study that has specifically selected for these traits over several generations and analyzed behavior-associated genes to elucidate genetic changes.
