Use of Insect Light Trap in Jasmine

Abstract

In 1985 and 1986 a study was made of the use of light traps to reduce the population of jasmine flower borer (Hendecasis duplifascialis Hampson) in plantings of jasmine. The study was done in Roi Et province of Northeastern Thailand.
Adult jasmine flower borers commenced to become active between 8 - 9 p.m. with the population reaching a peak between 2 - 4 a.m. The optimum height for positioning th elight trap was established as 0.5 meters above bush hights. A blue light trap was established as the most appropriate for attracting the jasmine flower borer. The light trap proved suitable for most types of insect pests of jasmine including Margavonia laticostalis, Nausinae perspicata and Archips micacena, togerther with insect pests of other crops grown nearby. The loss and damage to flowers in plots where the light trap was used was less than in plots where insecticided were used for control; the former method was also more economical.
