“…In field crops, lower insecticide dose/concentrations usually occur after the initial application, as they degrade by several abiotic factors, such as rainfall, temperature and sunlight. In this way, under field conditions, insects can be exposed to sublethal doses/concentrations of insecticides and may experience related to sublethal effects [3].…”

Studies related to the effect of insecticides on insect pests and nontarget organisms, such as natural enemies, are traditionally accessed by the estimative of lethal effects, through mortality data. Due to the limitations of the traditional methods, recent studies in the past three decades are assessing the sublethal effects of insecticides upon several important biological traits of insect pests and natural enemies. Besides mortality, the sublethal dose/concentrations of an insecticide can affect insect biology, physiology, behavior and demographic parameters. In this chapter, many sublethal effects of insecticides were addressed for several chemical groups, such as botanical insecticides, carbamate, diamide, insect growth regulators, neonicotinoid, organochlorides, organophosphates, pyrethroid and others. An accurate assessment of these effects is crucial to acquire knowledge on the overall insecticide efficacy in the management of pest insect populations, as well as on their selectivity toward nontarget organisms.

“…Although experimental methods are available for assessing behavioral changes (Pham-Delègue et al, 2002), these potential sublethal effects of Bt corn have not been addressed in current laboratory protocols. Thus, reliable experimental protocols that evaluate the potential risks of Bt crops on honey bees are needed (Stark et al, 1995, Hilbeck et al, 2000. Reported here are results of both laboratory and field studies to assess the effects of Bt pollen on honey bee survival, foraging activity, and colony performance.…”

-Laboratory feeding studies showed no effects on the weight and survival of honey bees feeding on Cry1Ab-expressing sweet corn pollen for 35 days. In field studies, colonies foraging in sweet corn plots and fed Bt pollen cakes for 28 days showed no adverse effects on bee weight, foraging activity, and colony performance. Brood development was not affected by exposure to Bt pollen but significantly reduced by the positive insecticide control. The number of foragers returning with pollen loads, pollen load weight, and forager weight were the most consistent endpoints as indicators of foraging activity. Using variances of measured endpoints, experimental designs required to detect a range of effect sizes at 80% statistical power were determined. Discussed are methods to ensure exposure to pollen, duration of exposure, positive controls, and appropriate endpoints to consider in planning laboratory and field studies to evaluate the nontarget effects of transgenic pollen.Apis mellifera / Cry1Ab / power analysis / transgenic plants / risk assessment

“…It is important to exercise caution when attempting to translate laboratory evaluations associated with indirect effects into predictions related to field performance of natural enemies [156][157][158][159]. Laboratory assays, for example, may fail to take into account the indirect effects of pesticides, which could underestimate their overall impact [18].…”
