“…The most common type of resistance is the removal of the insecticide from its site of action by detoxication (Perry & Agostin, 1974). The biotransformation (substances able to neutralize, inactivate, or eliminate foreign organic substances, including poisons or to avoid toxic damage) may involve oxidation, reduction, hydrolytic processes, and synthetic or conjugative reactions (Williams, 1959).…”

Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) is an important biological control agent of the cotton leafworm [Alabama argillacea (Hübner)] in the cotton crops in Brazil. The use of selective products such as pyrethroids has been emphasized in this agroecosystem. Then, the susceptibility of the predatory stinkbug P. nigrispinus to the pyrethroid insecticide gamma-cyhalothrin was studied in the laboratory. Nymphs and adults of the predator were exposed to seven concentrations of the gamma-cyhalothrin via topical contact and ingestion through treated water. The concentrations studied of this insecticide via topical application were relatively harmless for adults of P. nigrispinus (females: LC 50 = 143.5 ppm a.i., and males: LC 50 = 145.1 ppm a.i.) and 5th-instar nymphs (LC 50 = 103.9 ppm) as compared to via ingestion (females: LC 50 = 1.98 ppm a.i., males: LC 50 = 1.91 ppm a.i., and 5th-instar nymphs: LC 50 = 2.05 ppm a.i.). The use of pyrethroids and beneficial insects in IPM programs should be better evaluated.

O uso de produtos seletivos tais como piretróides tem sido enfatizado no agroecosistema do algodoeiro. Portanto, estudou-se em laboratório a suscetibilidade do percevejo predador Podisus nigrispinus (Dallas) ao inseticida piretróide gamma-cyhalothrin. As exposições via ingestão e aplicação tópica de ninfas de 5 o ínstar, fêmeas e machos de P. nigrispinus a gamma-cyhalothrin foram feitas, usando-se sete concentrações do inseticida. Gammacyhalothrin via aplicação tópica foi relativamente menos tóxico às formas adultas de P. nigrispinus (fêmeas: CL 50 = 143,5 ppm i.a. e machos: CL 50 = 145,1 ppm i.a.) e às ninfas de 5 o ínstar (CL 50 = 103,9 ppm) desse predador, quando comparado a sua utilização por ingestão (fêmeas: LC 50 = 1,98 ppm i.a., machos: LC 50 = 1,91 ppm i.a. e ninfas de para ninfas de 5 o instar: LC 50 = 2,05 ppm i.a.). Os resultados dessa pesquisa sugerem que o uso de piretróides em programas de MIP deve ser avaliado com bastante cautela.

“…The precise cause of the prolonged developmental times of the E strains compared with the N strains remains unclear. In this respect it is often found in insects, that long term exposure to detrimental substances (including insecticides) causes a genetically determined lengthening of developmental times associated with increased tolerance (Parsons, 1973;Perry and Agosin, 1974). non-survivors of FFN and SSN at the ethanol concentrations used indeed shows a linear relationship between mortality and amount of ethanol.…”

Strains of Drosophila melanogaster homozygous either for the AdhF or the Adhs allele, were kept on food supplemented with ethanol. After 90 generations these strains (FFE and SSE) were tested for tolerance to ethanol and compared with control strains (FFN and SSN) from regular food. The E strains showed increased tolerance to ethanol, both in the adult and in the juvenile life stages. In the adults the increase in tolerance was not accompanied by an increase in ADH activity. In the juvenile life stages there were significant differences in ADH activity between the E and N strains, both on regular food and on food containing ethanol. However, ADH activity was not the only factor involved in the increased tolerance to ethanol.The Adh genotype of the mother was of paramount importance to egg-to-adult survival because of a maternal effect on ethanol tolerance in the eggs and first instar larvae. Furthermore developmental times of the E strains were longer than those of the corresponding N strains. It is concluded that the adaptation to ethanol-containing food was not realised in the same way in the FFE and SSE strains.
