Abstract:

The result over fitness life parameters of Trichogramma revealed that the percentage emergence of Trichogramma recorded after 5 days of storage at different temperature revealed that 100C gave significantly highest emergence of parasitoid (96.20%) and was similar to control (97.4%) however; other temperatures, 12, 14 and 160C showed 90.90%, 89.43% and 88.33% emergence of Trichogramma, respectively. At 100C, the highest parasitism percentage (96.00%) was observed and further decreased to 53.66% at 100C when stored for up to 30 days whereas, the lowest parasitism percentage assessed at 16 (89.83%) and 60C (90.03%). The maximum adult longevity measured, while it was stored at 60C (4.50 days), whereas shortest adult longevity noted at 160C (3.00 days). Further, adult longevity was decreased from 4.26 to 0.00 days when stored at 10°C from 5 to 50 days. At 6oC, Trichogramma gave considerable emergence (76.13-20.63%) and parasitization (91.46-42.83%) from 5 to 50 days storage, whereas at 12, 14 and 16oC, development was completed during storage. It was evident that storage at 10oC and 6oC were very conducive for life parameters of Trichogramma to get short term and long storage, respectively.
