Abstract/Description: | Trichogramma pretiosum Riley is an important egg parasitoid on lepidopterans. Biological attributes of arrhenotokous and thelytokous T. pretiosum, was studied on Corcyra cephalonica under laboratory condition. The adult longevity in arrhenotokous and thelytokous T. pretiosum were 10.4 days and 10 days, respectively. The total female progeny produced during entire life span was 147.08 in thelytokous T. pretiosum and 90 in arrhenotokous T. pretiosum. The sex ratio of arrhenotokous T. pretiosum was 1:1 while for thelytokous it was 5:95 (M/F). The intrinsic rate of increase was 0.42 in arrhenotokous T. pretiosum and 0.48 in thelytokous T. pretiosum. These results revealed that in the net reproductive rate, weekly multiplication rate and the number of estimates in F2 generation are more in thelytokous T. pretiosum compared to arrhenotokous T. pretiosum. These results confirmed that biological attributes of arrhenotokous and thelytokous T. pretiosum are different. Thelytokous T. pretiosum have more practical implications in the field of biological control. |
