“…A high density of B. tamabae increases the number of available vacant galls for L. yadokariae in that season, but decreases the number of those in the following years, by reducing the population density of P. neolitseae (Yukawa et al . ).…”

The family Cecidomyiidae (Diptera) including about 6100 described species displays diverse feeding habits. The tribe Asphondyliini is a well-circumscribed monophyletic group of Cecidomyiidae and all species are known as gall inducers. Species belonging to this tribe exhibit fascinating ecological traits such as host alternation, polyphagy, extended diapause, induction of dimorphic galls and association with fungal symbionts. For these reasons, biogeographical and phylogenetic studies of Asphondyliini are of interest in elucidating the evolution of these traits, and particularly the processes of host-range expansion, host-plant shift and shifts in gall-bearing organs. In order to facilitate further evolutionary studies of Asphondyliini, I review studies of systematics, biogeography, phylogeny, speciation, cytology, behavior, ecology, physiology, biological interaction and economic importance in this tribe.

In the case of I. yukawai , the percentage parasitism varied yearly from 2.27 to 91.0% and 0 to 100% in 1‐yr and 2‐yr type populations, respectively, but there was no consistent tendency that the parasitism was higher either in the 1‐yr or the 2‐yr type population (Fig.…”

Illiciomyia yukawai (Diptera: Cecidomyiidae) induces leaf galls on Illicium anisatum (Schisandraceae) and exhibits 1‐year (yr) and 2‐yr type life history patterns. Geographical and annual variations in the proportion of 2‐yr to 1‐yr type individuals of I. yukawai were studied from 1977 to 1994 and in 2008, 2009 and 2014. An analysis of geographical variation at 13 different census fields indicated that the proportion of 2‐yr type individuals significantly increased with the decrease of mean annual temperature reflected by altitudinal and latitudinal gradients. However, a multiple regression analysis indicated that the annual variation in the proportion was not correlated with temperature, gall density, abundance of host resources or parasitism by hymenopteran parasitoids. Thus, we eliminated the effects of these external factors that have been thought to determine the annual variation. We need to take alternative intrinsic factors, instead of external factors, into consideration to explain the annual variation. The fall of galled leaves occasionally caused a higher mortality of 2‐yr type individuals than those of 1‐yr type. Nevertheless, 2‐yr type individuals exist. We considered that the existence of 2‐yr type individuals of I. yukawai has an adaptive significance to diversify risks against catastrophic events such as the serious shortage of host buds and high percentage of parasitism that happen more frequently than the high mortality caused by the fall of galled leaves.

“…From December to the following April, the females lay their eggs on the inner wall of mature galls or on the body surface of full‐grown host larvae or pupae including those that had already been parasitized by Gastrancistrus sp. The braconid larvae grow rapidly, and only one adult can emerge from a single host larva or pupa (Yukawa, ; Yukawa et al, ).…”

We evaluated effects of strong typhoons on populations of a gall midge Pseudasphondylia neolitseae (Diptera: Cecidomyiidae) and its associated arthropods through leaf fall of the host plant, Neolitsea sericea (Lauraceae). The very strong typhoon No. 13 in 1985 (“8513‐Pat”) caused heavy leaf fall particularly on forest edge trees, resulted in the larval death of gall midge and its endoparasitoid Gastrancistrus sp. (Hymenoptera: Pteromalidae). The typhoons were not directly responsible for the larval death of an ectoparasitoid Bracon tamabae (Hymenoptera: Braconidae) and a successor Lasioptera yadokariae (Diptera: Cecidomyiidae) that utilizes vacant galls after the departure of inhabitants. However, reduction in the number of galls possibly made their searching behavior for oviposition sites inefficient because their abundance relies on the gall density. The heavy leaf fall promoted lammas shoot production, which caused the reduction of number and length of the following spring shoots. The shortage of spring shoots must be influential to the gall midge females in searching oviposition sites, and the short spring shoots were not useful for oviposition and larval boring by Oberea hebescens (Coleoptera: Cerambycidae). We compared strength of the effects between the typhoons that attacked Kagoshima in 1985 and 1993, and Okinawa in 2015 and 2018, and concluded that typhoons with the maximum instantaneous wind velocity exceeding 50 m/s caused heavy leaf fall and lammas shoot production on N. sericea trees growing at forest edge but not on those inside forest.
