Studies were undertaken at IPM laboratory, Entomology Division, BARI, Gazipur during 2012-13 to develop a technique to release adult Trichogramma spp in the field. Host egg parasitism was 2.26 times (mean of three host eggs) higher in adult parasitoid emergence than parasitised eggs on paper strips in micro plot condition. The same trend was also observed in the open field condition, where egg parasitism was 2.42 times (mean of three host eggs) higher in adult parasitoid emergence than parasitised eggs on paper strips.

To develop a technique to release adult Trichogramma spp in the field.
This study was undertaken in the eggplant field in micro plot condition and in open field condition at BARI, Gazipur during March 2013 – May 2013. Parasitism efficacy of three different host eggs, viz. rice meal moth (Sitotroga cerealella), meal moth (Corcyra cephalonica) and eggplant shoot and fruit borer (Leucinodes orbonalis) eggs were evaluated by releasing Trichogramma chilonis through paper strip method (release during pupation period) and adult release methods in micro plot condition as well as in open field condition.
