We investigated the effects of fluctuating temperature on development and fertility of M. persicae at different temperature conditions, 10, 15, 20, 25, 28, and 30±5℃, respectively. In this study, we collected detailed data on development periods, and fertility of M. persicae at six different temperatures. We analyzed the life table parameters of M. persicae using age-stage, two-sex life table program. The intrinsic and finite rate of increase were the highest at 25±5℃. The fertiltiy was the highest at 20±5℃.

The oriental fruit fly, Bactrocera dorsalis, is one of important agricultural pests that attack a wide range of fruits and vegetables. Adult female can cause direct damage by laying eggs under the skin of fruits and vegetables. The eggs hatch into larvae that feed in the decaying flesh of the agricultural crops. Damaged fruits and vegetables quickly become inedible or dropto the ground. We investigated the oviposition characteristics of B. dorsalis on twelve fruits and seven vegetables. B. dorsalis marked the oviposition places on every crop tested. B. dorsalis laid eggs into the fruits and vegetables except lemon and passionfruit. We examined the adult emergence from infested crops.

We investigated the functional response of aphid parasitoid, Aphidius colemani Viereck (Hymenoptera: Braconidae), on the green peach aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae) at four different constant temperatures (15, 20, 25 and 30℃). Seven host densities (2, 4, 8, 16, 32, 64, and 128) were used during a 24-h period. A type III functional response for A. colemani was fit separately at each constant temperature. The estimated handling times at 15, 20, 25, and 30℃ were 0.85, 0.61, 0.41 and 0.88 day, respectively. The proportion of aphids that were parasitized showed the similar characteristics curve at four different constant temperatures.
