“…Therefore, biochemical substances produced by plants under pest attack (Hoffmann Campo et al, 2001;Piubelli et al, 2005) influence the growth, survival, and reproduction of insects (Fischer et al, 1990) and would be the better way to understand insect-host performance (Veenstra et al, 1995). A better understanding of the diversity of insect responses to these allelochemicals in their local ecological context represents a key challenge in developing durable pest control management (Després et al, 2007). Consequently, host-plant adaptation could be viewed in terms of physiological, biochemical, and evolutional adaptation to host-plant allelochemicals (Caprio and Tabashnik, 1992;Ahmad et al, 1986;Slansky, 1992;Sorensen and Dearing, 2006).…”

We studied Spodoptera frugiperda development using different food sources in the laboratory and field. Newly hatched larvae were fed soybean, cotton, maize, wheat, and oat leaves. An artificial diet was used as the control. Duration of pre-pupal, pupal, and larva-adult period, pupal weight, sex ratio, survival, larva feeding preferences, oviposition preferences, and nutritional quality of different hosts were evaluated. Insects fed on wheat showed the shortest larva-adult period. The insects fed on cotton and soybean had longer larval development cycles and pupae of lower weight. Feeding preference was evident for third instar larvae and did not differ between wheat, oat, maize, and soybean, which were the preferred hosts. Moths oviposited to a greater extent on the upper canopy of wheat than that of other plants in both the no-choice and free-choice tests. Treatments influenced insect growth, food consumption, and digestion when nutritional variables were analyzed. Thus, grasses were better hosts for S. frugiperda development. Cotton was the least preferred food, followed by soybean. The present study can improve our understanding of S. frugiperda in these different crops and help in developing management strategies. Even though S. frugiperda is considered to be polyphagous, this pest is closely associated with grasses (maize, wheat, oat) and has lower potential as a soybean or cotton feeder. Howerver, S. frugiperda food intake regulation appears to be triggered by a complex of different mechanisms. Thus, S. frugiperda can also damage soybean and cotton and adapt to them in the absence of preferred hosts.

“…At the metabolic level, resistance mechanisms of insects to both plant toxins and synthetic insecticides involve the induction of detoxification enzymes such as cytochrome P450s, which transform xenobiotics into less toxic and more soluble compounds that can be excreted (Després et al, 2007). The lack of effect of nicotine on honeybee larvae may be due to good detoxification abilities (du Rand et al, unpublished data).…”

The effects of pesticides on honeybee larvae are less understood than for adult bees, even though larvae are chronically exposed to pesticide residues that accumulate in comb and food stores in the hive. We investigated how exposure to a plant alkaloid, nicotine, affects survival, growth and body composition of honeybee larvae. Larvae of Apis mellifera scutellata were reared in vitro and fed throughout development on standard diets with nicotine included at concentrations from 0 to 1000 µg/100 g diet. Overall mortality across all nicotine treatments was low, averaging 9.8 % at the prepupal stage and 18.1 % at the whiteeyed pupal stage, but survival was significantly reduced by nicotine. The mass of prepupae and white-eyed pupae was not affected by nicotine. In terms of body composition, nicotine affected water content but did not influence either protein or lipid stores of white-eyed pupae.We attribute the absence of consistent negative effects of dietary nicotine to detoxification mechanisms in developing honeybees, which enable them to resist both natural and synthetic xenobiotics.

“…An analogous issue has been of persistent concern in the discipline of herbivory for decades. Although herbivorous animals generally possess a diverse array of detoxifying enzymes, including cytochrome P450 monooxygenases, glutathione S-transferases, and esterases (Despres et al 2007), symbiotic microorganisms have long been invoked to mediate the detoxification of plant allelochemicals (Jones 1984;Berenbaum 1988;Dillon and Dillon 2004). Supportive evidence comes from a few systems.…”
