Abstract

Trapping of Lymantria obfuscata Walker with disparlure.

Abstract

Field tests were carried out in the Kashmir Valley, India, in 1973 on capturing adult males of Lymantria obfuscata Wlk., an orchard pest, in traps baited with disparlure, the sex attractant of L. dispar (L.) (Porthetria dispar), emphasis being placed on attractant concentration, trap height and peak activity. A mixture of 1000 mu g disparlure and 2 mg trioctanoin was more attractive than mixtures of 100 and 10 mu g disparlure with 2 mg trioctanoin. Traps at a height of 3 m above ground level were the most effective. Maximum male activity occurred between 15.00 and 17.00 h. The attractiveness of a wick containing a mixture of 100 mu g disparlure and 2 mg trioctanoin was equivalent to that of a single virgin female.
