“…The activation by midgut esterases from the tobacco hornworm, Manduca sexta (L.) was inhibited by DEF (Kranthi et al, 2002). Sayyed et al (2010) demonstrated that PBO reduced the LC 50 for deltamethrin (8 fold), alphamethrin (3-fold) and lambdacyhalothrin (1.6-fold) in deltamethrin resistant strain of C. carnea which is in conformity with our present study.…”

“…The study further supports our findings that the predator from Sriganganagar (CZS-8) developed resistance not only to monocrotophos but also to endosulfan, fenvalerate and acephate with RR increased to 50.36-fold, 66.11-fold and 277.51-fold, respectively, compared to susceptible. Sayyed et al (2010) reported RRs of 47, 86, 137, 76 and 110 for deltamethrin, alphamethrin, lamdacyhalothrin, chlorpyrifos and profenofos for resistant C. carnea as compared to lab population in Pakistan, which was in conformity with our study. Natural tolerance to pyrethroid in C. carnea has been reported [Plapp and Bull, 1978).…”

“…Among the natural enemies, Amblyseius chilenensis was the first predatory mite found resistant to chemical pesticides (Kranthi et al, 2002). Similarly, insecticide resistance in different geographical populations of Chrysoperla carnea in Pakistan was earlier reported [Pathan et al, 2008;Sayyed et al, 2010;Venkatesan et al, 2009). Hence it may correct that chrysopid predators in India and Pakistan is being increasingly developed resistance to insecticides especially from the cotton which could be due to heavy insecticidal sprays used to control the sucking pests especially for the newly introduced cotton mealybug Phenococus solenopsis.…”

“…It has long been considered as a promising candidate for pest management programs worldwide due to its wide prey range and geographical distribution, voracious larval feeding capacity and commercial availability (Medina et al, 2003;Pathan et al, 2010;Sayyed et al, 2010). Parasitoids and predators are highly susceptible to insecticides than their host insects [Croft and Brown, 1975), which make them difficult to establish in insecticide sprayed field.…”

“…In a study conducted from 2007 to 2009, monocrotophos resistance was documented in field populations of C. zastrowi sillemi (Venkatesan et al, 2009). Chrysopid predators have been found resistant to insecticides in USA (Grafton and Hoy, 1985), Pakistan (Pathan et al, 2008;Sayyed et al, 2010), India (Venkatesan et al, 2009) & Canada (Pree et al, 2009). In a study, significantly higher fitness attributes viz., intrinsic rate, survival rate, doubling time and predation rate has been reported in organophosphate and pyrethroid resistant populations of C. carnea (Pathan et al, 2008) contrary to general belief of genetic trade-off in such attributes in insects.…”

ABSTRACT:The toxic effect of commonly used insecticides in cotton fields was studied on 9 populations of Chrysoperla zastrowi sillemi (Esben-Petersen), an important predator of sucking pests collected in India. The dose mortality bioassay against 3-days old larvae was determined using three insecticides viz., endosulfan, fenvalerate and acephate by topical bioassay method. Mechanism of resistance to the above mentioned insecticides were determined without and with three metabolic inhibitors (synergists), viz., piperonyl butoxide (PBO), S,S,S-tributyl-phosphorotrithioate (DEF) and diethyl maleate (DEM). Among the populations, resistant ratios (RR) of CZS-8 was significantly higher i.e. 50.36., 66.11 and 277.51-fold for endosulfan, fenvalerate and acephate, respectively compared to susceptible population (CZS-10). The CZS-8 was selected for synergism study it showed higher LC 50 values and resistance ratio for all three insecticides. It showed 8.97-fold, 18.49-fold and 6.38-fold increase in synergism ratio for endosulfan indicating the resistance was strongly synergised by PBO, DEF and DEM. Similarly for fenvalerate, CZS-8 showed 8.69-fold and 3.63-fold significant increase in synergism ratio by DEF and DEM, respectively and for acephate, CZS-8 showed 54.82-fold, 150.87-fold and 113.52-fold significant increase in synergism ratio indicating that the resistance could be due to cytochrome p-450, esterase and glutathione s-transferase activity. The study indicated that the field population of C. z. sillemi developed resistance to different groups of insecticides. Among different geographical populations, CZS-8 collected from Sriganganagar, was recorded as most resistant.
