Developmental Performance and Parasitism of Trichogramma chilonis Ishii on Eggs of the Oriental Tobacco Budworm, Helicoverpa assulta (Guenee), and the American Bollworm, Helicoverpa armigera (Hubner) Depending on Previous Hosts
pp.393-400
The parasitism, development time, hatchability, and progeny production of Trichogramma chilonis(TC) females developed in eggs of Helicoverpa assulta (HAs), Cadra cautella (CC), and Helicoverpa armigera (HAr), repectively, were compared with those developed in reciprocal eggs at constant temperatures of 25±2℃ and relative humidity of 50～70% under 16L-8D. Developmental performances of TC reared in each of the three hosts on the following hosts(host tested) appeared differently, and were affected most by the size of the proceeding hosts and test host. Among the parameters parasitism and progeny production were affected more than others. Parasitism was significantly different between the treatments, lowest in CC-HAr(10.1±2.05%) and highest in HAr-HAs(47.0±2.09%), and the hatchability showed similar pattern. Development time as well was shortest in the CC-HAr where previous host is smallest and test host is biggest. The highest number of progeny production of TC was observed in HAr-HAs(93.9±6.87 wasps), and the lowest was CC-HAs(18.4±6.36 wasps).
