“…In the glasshouse and field studies, the significantly lower numbers of parasitoids recorded on, or in the vicinity of, insecticide-treated plants will have resulted from a combination of reduced residence times of parasitoids on the plants (Jiu & Waage, 1990;Borgemeister et al, 1993;Longley & Jepson, 1996) and a repellent effect by the insecticide (Elzen et al, 1989;Pike et al, 1982;Longley & Jepson, 1996). Repetlency can occur through the masking of attractive plant odours and/or interference with the receptors that detect the odours (Haynes, 1988).…”

The opposing effects of attraction to host‐derived kairomones and repellency from the pyrethroid insecticide deltamethrin were investigated with aphid parasitoids from the genus Aphidius (Hymenoptera: Aphidiinae). The spatial distribution of female parasitoids was recorded in a series of experiments conducted in a small glasshouse containing wheat plants either infested with cereal aphids, Sitobion avenae (F.) (Homoptera: Aphididae), uninfested or treated with the recommended field concentration of deltamethrin. The number of parasitoids per plant were counted at 0.5 h, 1 h and then at one hourly intervals up to 8 h after release. Parasitoids showed a strong aggregation response to aphid‐infested plants compared to adjacent uninfested plants. With the introduction of insecticide‐treated plants around the aphid‐infested plants, parasitoids showed a greater tendency to disperse away, resulting in fewer parasitoids on plants and significantly lower rates of aphid parasitism. The degree of aphid fall‐off from plants was a good indicator of parasitoid foraging activity. In field studies, using sticky traps to measure the activity of parasitoids in plots sprayed with water, deltamethrin and/or an artificial honeydew solution, repellent properties were evident for up to 2 days after application. The attraction/arrestment stimuli associated with the honeydew solution were sufficient for parasitoids to continue searching insecticide‐treated areas. The implications of these findings for parasitoids searching crops contaminated with aphid‐derived kairomones and insecticides are discussed.

“…Adult boll weevils given a choice between in secticide-laden and uncontaminated diets for feeding and oviposition avoided diets containing a pyrethroid (decamethrin) and an organophosphate (methyl parathion) (6 1). Pike et al (68) reported that bee visitation to permethrin treated fields was greatly reduced, and bees foraging in the treated fields seldom contacted the treated foliage. They suggested that this effect was due primarily to repellency, but the role of mortality was not ruled out.…”

PERSPECTIVES AND OVERVIEWThe behavior of insects, and all animals, is governed by interactions among neurons within their nervous systems. Insecticides have been selected and sometimes designed for their remarkable ability to kill insects. Most attack specific sites within the insect's nervous system (59, 63; see section on modes and sites of action). Therefore it is not surprising that insecticides at levels that do not lead to mortality can influence behavior. However, there have been few detailed studies concerning the potential behavioral effects of sublethal doses of insecticides.Studies of the behavioral effects of neurotoxic ants are important for several reasons (89). First, detailed observations of the behavioral symptoms of poisoned insects will help to elucidate the modes of action of both novel and conventional insecticides. Second, it is clear that almost all insecticides interfere with the normally well-orchestrated behavioral patterns of pest insects and thus might contribute to management of their populations. An important related point is that beneficial insects may be adversely affected by these compounds in a way that is overlooked by current screening procedures.Lastly, selection may favor those insects that respond to insecticides in the environment by minimizing their contact with the toxic material; thus the potential for evolution of behavioral resistance to insecticides is another important consideration.Insecticides are the cornerstones upon which pest management practices are based, and are likely to remain so as long as effective and inexpensive chemicals are available. However, many insect-pest management techniques
