Insect and Mite Galls Collected from Peucang, Panaitan, and the Krakatau Islands, Indonesia.

Abstract

(Dammerman, 1948. They were well illustrated and described together with their collection data in the book of Docters van Leeuwen-Reijnvaan and Docters van Leeuwen (1926) [hereafter, 'the book' or 'DvLR and DvL (1926)1, which also included many other galls collected by them ftom various localities in Indonesia. This book is, therefore, quite useful in identifying the Indonesian galls. In addition, insect and mite galls are relatively convenient material for a faunistic study due to their species specificity in shape, galled portion, and host plant. Nevertheless, the recolonization by gallers was not surveyed after the 1920s until the 1980s. By taking these advantages into consideration and to provide additional information, we devoted considerable time to the collection of galls during

Biology of Asphondyliini (Diptera: Cecidomyiidae)

“…In addition, some gall‐inducing cecidomyiids were found to have established, probably by wind‐blown dispersal (passive flight), on the Krakatau Islands, Indonesia, which are about 40 and 35 km apart from Java and Sumatra, respectively (Docters van Leeuwen‐Reijnvaan & Docters van Leeuwen ; Yukawa & Partomihardjo ; Partomihardjo et al . ).…”

Description and ecological traits of a new species of Pitydiplosis (Diptera: Cecidomyiidae) that induces leaf galls on Pueraria (Fabaceae) in East Asia, with a possible diversification scenario of intraspecific groups

“…Two cecidomyiid galls exist on leaflets of P. lobata in Japan (e.g. Yukawa & Masuda 1996). One is a pale green globular gall on the underside of the leaf blade and the other is a thick lenticular gall frequently with an acute tip on both sides of the leaf blade .…”

Descriptions of two new species of Platygaster Latreille that attack gall midges (Diptera, Cecidomyiidae) with notes on their biology (Hymenoptera, Platygastridae)

“…Platygaster urniphila is an egg-larval gregarious parasitoid of Rhopalomyia longitubifex that induces axillary bud galls on Artemisia indica var. maximowiczii in Japan (Yukawa and Masuda 1996; Ganaha et al 2007). Gall polymorphism has been found in R. longitubifex : long jar-shaped, jar-shaped, and globular jar-shaped (see figures 1–5 of Ganaha et al 2007).…”

“…(e.g. Yukawa and Masuda 1996; Yukawa 2014; Gagné and Jaschhof 2017), but P. urniphila has been reared only from galls of Rhopalomyia longitubifex on A. indica var. maximowiczii in Japan. Future intensive studies are needed to confirm the host range of P. urniphila .…”

“…This Platygaster species avoids hyperparasitism by manipulating larvae of the host gall midge to make leaf galls thicker (Fujii et al 2014). Another species parasitizes Rhopalomyia longitubifex (Shinji) (Diptera: Cecidomyiidae) that induces axillary bud galls on Artemisia indica var. maximowiczii (Asteraceae) (Yukawa and Masuda 1996; Ganaha et al 2007). …”
