Effect of storage temperature on different biological parameters of Trichogramma chilonis survivability

Abstract

Developing efficient storage technique to produce quality parasitoids is essential for successful bio-control programs. In this study three different temperatures for six weeks were tested for best storage temperature and periods. Testing of survivability of B. hebetor and T. chilonis during storage at different temperatures revealed that in T. chilonis adult emergence was seen up to six weeks but at 5oC and 95 to 97% RH almost 50% survivability was recorded up to five weeks. At 10oC and 70 to 75% RH approx 50% survivability found up to four weeks and 15 0C and 85 to 89% RH upto 50% survivability was recorded only for two weeks.
