Effects of neem oil on feeding behaviour and development of the pear sawfly, Caliroa cerasi

Neem oil deterred feeding by pear sawfly, Caliroa cerasi L., larvae (Hymenoptera: Tenthredinidae), both in choice and in no-choice cherry leaf disk bioassays. Deterrence was greater in the choice tests, with 50% inhibition occurring at 0.49% aqueous neem oil compared with 1.11% in the no-choice tests. Antifeedant activity towards pear sawfly larvae is slightly less than has been observed for Lepidoptera, but is higher than deterrence to other insects such as aphids. Topical application of neem oil to sawfly larvae resulted in reduced feeding, increased mortality, and a trend towards slower development. Most larval mortality after neem treatment resulted from incomplete subsequent moults. The potential utilization of neem insecticides for control of pear sawfly in tree fruit pest management is discussed.
