Sugar derivatives containing oxiranes and alpha,beta-unsaturated gamma-lactones as potential environmentally friendly insecticides

摘要

A range of novel sugar derivatives containing oxiranes or alpha,beta-unsaturated gamma-lactones in their structure were evaluated as potential insecticides with the added possible benefit of being benign in the environment.A number of arthropod species were chosen to represent those in the terrestrial,aerial and aquatic environments,covering target adult insects such as Musca domestica L (housefly) and Trialeurodes vaporariorum (Westwood) (glasshouse whitefly),which are public health and horticultural pests,Drosophila melanogaster Meig (fruitfly),both adult and larva,and a marine non-target crustacean,Artemia salina L.The tested compounds possessed efficacy and selectivity against these insect species,but were not toxic to brine shrimps,a reference organism in assays to evaluate the potential toxicity hazard to invertebrates in ecosystems.
