The effects of adult male and female size on reproductive performance in Agrothereutes lanceolatus Walker, a solitary ectoparasitoid of mature larvae and pupae of several pyralids and tortricids, were investigated. Females had a longer mean lifetime than males. Larger females lived longer, whereas the size of males did not influence the longevity. The number of ovarioles per female did not differ among females of different sizes but larger females carried a greater number of mature and immature eggs. When presented with host cocoons, large females parasitized a higher percentage of hosts than small females. This was due to the fact that larger females accepted more hosts for oviposition whereas smaller ones rejected more hosts. Small and large females used equal numbers of hosts for host‐feeding, suggesting that large females removed a greater amount of materials from single hosts through host‐feeding.

“…As a result, if we combine the two parameters, the estimated developmental period of egg, larval and pupal stages is about 16 days for B. lasus females, and 31 days for H. magnanima at 25 ~ C; there is a difference of two weeks between the parasitoid and the host. lasus (Mao & Kunimi, 1991). When B. lasus adults were fed with 10~o sugar solution, the female adults survived more than four months, whereas with 1~o sugar solution, the female adults survived for only 11 days (Mao & Kunimi, unpublished).…”

“…These parasitoids have been thought to be generalists rather than specialists, since they have been reported in other microlepidopteran hosts (Habu, 1960;Momoi et al, 1975;Yukinari, 1984;Mao and Kunimi, 1991;Ueno and Tanaka, 1994;Sugiura, S., unpublished data).…”

“…was observed to parasitize the larvae of other polyphagous leafrollers on M. rubra in June at the new plantation (Sugiura, S., personal observation). G. japonicus and B. excarinata have been reported to attack various lepidopteran species (Habu, 1960;Momoi et al, 1975;Yukinari, 1984;Mao and Kunimi, 1991;Ueno and Tanaka, 1994;Sugiura, unpublished data). Therefore, the parasitoids recorded at the new plantation were thought to be polyphagous.…”

To clarify the immigration process of a phytophagous insect to a new habitat, I examined seasonal changes in the abundance and parasitism of larvae and pupae of a leafroller, Eudemis gyrotis (Meyrick) (Lepidoptera: Tortricidae), at both a new and an old plantation of the bayberry Myrica rubra Sieb. et Zucc. (Myricaceae) on Mt. Tanakami, Shiga Prefecture, central Japan, in 1999. E. gyrotis adults singly lay eggs on only young leaves of M. rubra, and their larvae feed on the leaves. Therefore, the young leaves of M. rubra are necessary for the occurrence of E. gyrotis larvae. The number of E. gyrotis larvae per tree was correlated with the amount of young leaves per tree. At the old plantation where E. gyrotis had already been found in 1998, the larval occurrence of E. gyrotis began in late May. At the new plantation, which was at a distance of ca. 600 m from the old plantation, E. gyrotis larvae had not occurred by late July, although there was an abundance of young leaves of M. rubra in late May. These findings suggest that E. gyrotis adults that had emerged from the old plantation in July immigrated to the new plantation and laid eggs on the plants there. The parasitoids that attacked E. gyrotis at the new plantation just after immigration were polyphagous. This suggests that those parasitoids switched hosts from other herbivore species to E. gyrotis. In spite of the attack by polyphagous parasitoids, the E. gyrotis population successfully established itself at the new plantation.
