Response of Trichogramma Pretiosum and T. Evanescens to Whitelight, Blacklight or No-Light Suction Traps
Abstract
The response of Trichogramma pretiosum Riley and T. evanescens Westwood to blacklight, whitelight, or no-light suction traps in empty 44.7 m^3 rooms showed that significantly more (P < 0.01) of both species responded to blacklight than to whitelight or no-light traps. About 40% and 60% of the T. evanescens and T. pretiosum, respectively, were caught in the blacklight trap. No significant difference (P > 0.05) was found in the response of T. pretiosum to whitelight and no-light traps, while significantly more (P < 0.05) T. evanescens were caught in the whitelight trap than in the no-light trap. Females, especially those of T. evanescens, appeared to be more responsive than males as more females than males of both species were usually caught. The implications of these findings should be considered in planning releases of Trichogramma for control of storage moths in warehouses.Downloads
