“…Such tests are important in defining the impact of insecticides on ladybird beetles in terms of designing IPM programmes. With the exception of a possible resistance to the pyrethroid bifenthrin mentioned by Kumral et al (2011) in the coccinelid Stethorus gilvifrons (Mulsant), all other reports show incompatibility of the studied ladybird species with pyrethroid insecticides. In fact, there are very few examples of organic synthetic insecticides being compatible with ladybirds that can be safely recommended within an IPM approach; these include chemicals such as pymetrozine, pirimicarb, and some growth regulators for ladybird adults (Torres et al, 2003;Cabral et al, 2008).…”

The ladybird beetle, Eriopis connexa (Germar) (Coleoptera: Coccinellidae), is one of the commonest predators of aphids (Hemiptera: Aphididae) in the cotton agroecosystem and in many other row and fruit crops in Brazil, and has been introduced into other countries such as the USA for purposes of aphid control. In addition, the boll weevil, Anthonomus grandis Boheman (Coleoptera: Curculionidae) is the most serious cotton pest where it occurs, including Brazil. Controlling boll weevils and other pests such as cotton defoliators still tends to involve the intense application of insecticides to secure cotton production. The pyrethroid insecticide lambda-cyhalothrin (LCT) is commonly used, but this compound is not effective against aphids; hence, a desirable strategy would be to maintain E. connexa populations in cotton fields where LCT is applied. Using populations of E. connexa resistant (Res) and susceptible (Sus) to LCT, we compared behavioural responses on treated cotton plants and under confinement on partially and fully treated surfaces, and assessed the insects' survival on treated plants compared with that of the boll weevil. The E. connexa resistant population caged on treated plants with 15 and 75 g a.i. ha-1 exhibited ≫82% survival for both insecticide concentrations compared with ≪3% and ≪17% survival for susceptible E. connexa populations and boll weevils, respectively. The response of E. connexa Res and Sus populations when released, either on the soil or on the plant canopy, indicated avoidance towards treated plants, as measured by elapsed time to assess the plant. When compared with susceptible individuals, resistant ones took longer time to suffer insecticide knockdown, had a higher recovery rate after suffering knockdown, and spent more time in the plant canopy. Based on behavioural parameters evaluated in treated arenas, no ladybird beetles exhibited repellency. However, irritability was evident, with the susceptible population exhibiting greater irritability compared with the resistant population and a subgroup comprising resistant individuals that had recovered from knockdown. The outcomes for the E. connexa Res population indicate a promising strategy for its maintenance when using the insecticide LCT in integrated pest management schemes to control boll weevil or other non-target pest of ladybird beetles in cotton fields.

1 The present study assessed the fitness of a lambda-cyhalothrin-resistant population of Eriopis connexa (Germar) with respect to development, reproduction, survival under prey scarcity and prey consumption. 2 Nontreated resistant females (R0) and females recovered after the topical application of 0.05, 0.10 and 0.25 mg active ingredient/mL of lambda-cyhalothrin (R0.05, R0.10 and R0.25) produced, on average, 50% less eggs than susceptible females (S0), irrespective of the applied dose. All of the other traits evaluated remained similar. With respect to developmental characteristics, the larval viability and weight of adult male R0.25 progeny were statistically lower compared with the R0 and S0 progenies. Prey scarcity between days 3 and 13 of adulthood did not affect R0 and R0.25 survival, although egg production was significantly lower for R0 females, followed by R0.25 females, compared with S0 females. 3 The mean consumption of cotton aphids Aphis gossypii Glover over 5 consecutive days was significantly higher for S0, followed by R0 and R0.25, up to day 3 of observation. However, after day 4, prey consumption was similar among the three populations. 4 The results obtained in the present study show that resistant females have a lower reproductive output than susceptible females and that this is not related to the knockdown effect; however, the costs of recovering from knockdown interfere with the survival of offspring and also slightly with prey consumption. Thus, we conclude that the lambda-cyhalothrin-resistant E. connexa population exhibits an egg production disadvantage relative to the susceptible population and that this is increased when the population is subjected to prey scarcity.

“…Among predatory species, it has been shown that the natural enemies could also develop resistance to insecticides corresponding to that in the pest insects ( Georghiou 1986 , Pathan et al 2010 , Sayyed et al 2010 , Alperkumral et al 2011 , Rodrigues et al 2013 , Torres et al 2015 ). The resistance to parathion-methyl and bifenthrin in Stethorus gilvifrons (Coleoptera: Coccinellidae) ( Alperkumral et al 2011 ) and to pyrethroid in Eriopis connexa ( Torres et al 2015 ) was reported. Elevated detoxification and insensitivity target were thought to be involved in resistance to insecticides in spider mites ( van Leeuwen and Tirry 2007 ).…”

“…Elevated detoxification and insensitivity target were thought to be involved in resistance to insecticides in spider mites ( van Leeuwen and Tirry 2007 ). The comparative studies in terms of detoxification enzymes and insensitivity were very limited for predacious coccinellids ( Alperkumral et al 2011 ). Resistance-related genes were studied by gene expression proﬁle analysis of responses to insecticide in Cryptolaemus montrouzieri (Coleoptera: Coccinellidae) ( Zhang et al 2012 ) and Propylaea japonica (Thunberg) ( Tang et al 2014 ) based on transcriptome and digital gene expression analysis.…”

Multiple biochemical resistance mechanisms, including elevated carboxyestsrases (CarE) and GST activity and target-site insensitivity (insensitive acetylcholinesterase [AChE]) were involved in the resistance mechanisms in S. gilvifrons ( Alperkumral et al 2011 ). As compared with susceptible strain, insecticide-resistant E. connexa showed significantly higher survival rate ( Torres et al 2015 ).…”

Propylaea japonica (Thunberg) was a dominant species among the predacious ladybirds in the fields and active from March to November during a year in Fuzhou, China. Stability of insecticide resistance and vitality in adult P. japonica were investigated. The field ladybird P. japonica in Fuzhou, China, showed 9- to 16-fold resistance ratios to chlorpyrifos, 13- to 2,083-fold to methamidophos, 32- to 230-fold to fenvalerate, and 4- to 49-fold to avermectins, respectively, based on the field monitoring during 2004, 2009, and 2012, as compared with insecticide-susceptible F39 progenies. The resistance levels in the field P. japonica were high during May and November but low during summer. The population growth tendency index in field P. japonica was 0.8-fold as high as that in insecticide-susceptible P. japonica. The field P. japonica also showed high tolerance to the insecticide as compared with pest Lipaphis erysimi Kaltenbach and two parasitoids Diaeretiella rapae and Pachyneuron aphidis. Stable insecticide resistance levels and high vitality were found first in adult P. japonica with 1-, 30-, or 60-d-old adults, or among the adults developed form the eggs produced by newly emerged adults or by 60-d-old adults. Increased activity of glutathione S-transferases, carboxylesterases, and cytochrome P450 monooxygenases might be involved in the resistance of P. japonica. The results indicated that, in certain areas, inclusion of P. japonica for pest control in the integrated pest management would be highly recommended.
