“…2). Através da comparação das exigências térmicas de B. salubricola (temperatura base e constante térmica de 6,8°C e 745 graus dias, respectivamente) obtidos por Botton et al (2000), com as exigências térmicas de T. pretiosum "linhagem bonagota" obtidos nesta pesquisa, pode-se prever que, ao longo do ano, o número de gerações desses parasitóides será sempre maior que o de B. salubricola, característica esta importante para um programa de controle biológico.…”

“…As lagartas de B. cranaodes se abrigam em cartuchos formados por folhas ou no cálice de frutos, enquanto as lagartas de G. molesta alojam-se no interior dos ponteiros ou de frutos. O controle geralmente é realizado por meio de inúmeras aplicações de inseticidas de amplo espectro, principalmente organofosforados (Botton et al, 2000).…”

Resumo -O objetivo deste trabalho foi avaliar a seletividade de 12 agrotóxicos usados na produção integrada de maçã, em laboratório (temperatura 25±1 o C, umidade relativa 70±10% e fotófase de 14 horas), tendo-se exposto adultos de Trichogramma pretiosum a resíduos secos dos agrotóxicos, na máxima dosagem recomendada para uso em campo, e tendo-se posteriormente mensurado o número de ovos parasitados por fêmea. Reduções no parasitismo, em relação à testemunha (água), foram utilizadas para classificar os agrotóxicos em inócuo (<30%), levemente nocivo (30-79%), moderadamente nocivo (80-99%) e nocivo (>99%). Foram inócuos os acaricidas Envidor (espirodiclofeno), Kendo 50 SC (fenpiroximato) e Ortus 50 SC (fenpiroximato), os fungicidas Antracol 700 PM (propinebe), Midas BR (famoxadona + mancozebe), Palisade (fluquinconazol), Persist SC (mancozebe) e Systhane PM (miclobutanil) e o inseticida Mimic 240 SC (tebufenozida); o herbicida Polaris (glifosato) foi levemente nocivo; os herbicidas Finale (glufosinato sal de amônio) e Roundup Original (glifosato) foram moderadamente nocivos a T. pretiosum.Termos para indexação: parasitóide de ovos, manejo integrado de pragas, pesticidas. Side effects of pesticides used in integrated production of apple in adults of Trichogramma pretiosumAbstract -The objective of this work was to evaluate the side effects of 12 pesticides used in the integrated production of apple, in laboratory (25±1 o C temperature, 70±10% relative humidity and 14 hours photophase), exposing adults of Trichogramma pretiosum to fresh dry pesticide film, in the maximum dosage recommended for field use, with subsequent assessement of the number of eggs parasitized per female. The reduction in the parasitism, compared with the control (water), was used to classify the pesticides as harmless (<30%), slightly harmful (30-79%), moderately harmful (80-99%) and harmful (>99%). The acaricides Envidor (spirodiclofen), Kendo 50 SC (fenpyroximate) and Ortus 50 SC (fenpyroximate), the fungicides Antracol 700 PM (propineb), Midas BR (famoxadone + mancozeb), Palisade (fluquinconazole), Persist SC (mancozeb) and Systhane PM (myclobutanil) and the insecticide Mimic 240 SC (tebufenozide) were harmless; the herbicide Polaris (glyphosate) was slightly harmful; the herbicides Finale (gluphosinate-ammonium) and Roundup Original (glyphosate) were moderately harmful to T. pretiosum.

“…Tebufenozide and novaluron are the only insect growth regulators (IGRs) registered against C. molesta in Brazil (Andrei 2009). These insecticides are aimed to control simultaneously C. molesta and secondary pests, including Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) and Bonagota cranaodes (Meyrick) (Lepidoptera: Tortricidae) (Botton et al 2000).…”

In southern Brazilian apple (Malus spp.) orchards, predominantly organophosphates are used to control the oriental fruit moth, Cydia molesta (Busck) (Lepidoptera: Tortricidae), but control failures often occur. Therefore the susceptibility of three C. molesta Brazilian populations was investigated to five insecticides of different groups and modes of action, in comparison with a susceptible laboratory strain mass reared in southern France for >10 yr. At the same time, comparative biochemical and genetic analysis were performed, assessing the activities of the detoxification enzymatic systems and sequencing a gene of insecticide molecular target to find out markers associated with resistance. The three Brazilian populations were significantly resistant to chlorpyrifos ethyl compared with the reference strain. One of the field populations that had been frequently exposed to deltamethrin treatments showed significant decreasing susceptibility to this compound, whereas none of the three populations had loss of susceptibility to tebufenozide and thiacloprid compared with the reference strain. All three populations had slight but significant increases of glutathione transferase and carboxylesterases activities and significant decrease of specific acetylcholinesterase activities compared with the reference. Only the most resistant population to chlorpyriphos exhibited a significantly higher mixed function oxidase activity than the reference. The acetylcholinesterase of females was significantly less inhibited by carbaryl in the Brazilian populations than in the reference strain (1.7-2.5-fold), and this difference was not expressed in the male moth. However, no mutation in the MACE locus was detected. These biological and molecular characterizations of adaptive response to insecticides in C. molesta provide tools for early detection of insecticide resistance in field populations of this pest.
