Abstract The movement behavior of the pine needle gall midge (Thecodiplosis japonensis Uchida Et Inouye (Diptera: Cecidomyiidae)), an invasive species in China, was determined by using a tethered flight technique and digital videography in the laboratory. The flight distance, duration, and speed of females were compared at different ages (2–10 h) and ambient temperatures (17, 21, 26, and 30°C). Female flight distance and duration at 26°C were significantly greater than those at 17°C and 21°C. The age of T. japonensis did not significantly affect the three flight characteristics. For females at 2–10 h of age at 26°C and 70% RH, the maximum flight distance was 667.59 m; the longest flight time was 6,222.34 s; and the fastest flight speed was 0.44 m·s−1. For larvae wetted with water, the highest jump was 5.7 cm; the longest jump was 9.6 cm; and the greatest distance moved in 5 min was 27.13 cm, which showed that the active dispersal potential of larvae was very low.

Pine Needle Gall Midge

The endophytic mycobiota of the galls of pine needle gall midge, Thecodiplosis japonensis, and healthy current-year needles of Pinus densiflora and the F2 hybrid pine (Pinus thunbergii × (P. thunbergii × P. densiflora)) was compared. Phialocephala sp. was the dominant endophyte isolated from the galls and from the basal regions of healthy needles. Species richness in endophytes was facilitated in galls compared to the basal region of healthy needles, and the commencement of their colonization was hastened in galls. In the early stages of gall formation, however, no endophyte was isolated, suggesting that gall endophytes are not carried into the galls by the midge. Endophytes of healthy and galled pine needles were divided into two groups: position-specific fungi, which showed intrinsically restricted distributions on needles; and gall-specific fungi. These two groups might represent different ecological groups of endophytes. Possible interactions between endophytes and the pine needle gall midge are also discussed. Key words: endophytic fungi, Pinus densiflora, F2 hybrid pine, pine needle gall midge.
