Description
Summary:The Asian citrus psyllid Diaphorina citri (Kuwayama) (Hemiptera: Psyllidae) is a serious pest and main threat to citrus production worldwide. The present study was carried out to assess the performance of T. radiata as biological control agent of D. citri under insectary condition. The result shows T. radiata to preferred late (4th and 5th) instar nymphs than early (1st 2nd and 3rd) instar nymphs of D. citri with mean parasitism rate of 0% 0% 43.3% 76.9% and 86.0% for 1st 2nd 3rd 4th and 5th instar nymphs respectively. The binomial logistic regression analysis of D. citri nymphs attacked by T. radiata as a function of host (D. citri nymphs) density offered shows T. radiata to display a functional response type II with attack rate of 39.99 and 34.04 and handling time of 0.60 and 0.71 for 4th and 5th instar nymphs of D. citri respectively.
