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

Insecticide resistance is a broadly recognized ecological backlash resulting from insecticide use and widely reported among arthropod pest species with well-recognized underlying mechanisms consequences. Nonetheless, the subject of evolving conceptual views that introduces different concept useful if in its own right - risk or likelihood control failure. Here we suggest an experimental approach to assess failure allowing for consistent decision-making regarding management resistance. We also challenge current emphasis on limited spatial sampling populations diagnosis favor comprehensive sampling. This necessarily requires larger population aiming analysis area-wide surveys recognize focal points and/or will better direct efforts. The continuous geographical scale such depend species, pattern many other potential factors. Regardless, distance dependence sites should still hold, following maxim closer two things are, more they resemble each other, which basis Tobler's First Law Geography. © 2016 Society Chemical Industry.
