The results showed that both male and female were fourteen segmented, the male was approximately 2000 μm and the female was 1050μm. Six types of sensillae on the antenna were observed, viz. chaetica （Ch）, trichoidea （Tr）, basiconica （Ba）, cavity （Ca）, styloid （St） and circumfila （Ci） on the antennae of A. aphidimyza. Sensillae Ch had a long external-process, with a base surrounded by membranous sockets and a length of about 67.5 μm. Sensillae Tr were distally curved and inserted into a depression, 61.0μm long. Sensillae Ba were peg-like and 4.7μm long on the antennae. Sensillae Ca were pit-like in appearance and the diameter of the pit was 1.2μm. Sensilla St was found on the second sub-segment flagellum of the male antennae. The length of the sensilla was about 21 μm and the diameter was 1.5μm. The circurnfila, which are a unique type of sensilla found only on cecidomyiid antennae, formed loops around each of the antennal sub-segments, and were attached to the surface by a series of stalks. Sensilla St was only present on male antenna. The number of Ba and Tr was almost the same in both sexes. There were more Sensilla Ca on the male antenna than on the female, while there was more Ch on the female.展开更多

[ Method] The Guangxi local cultivar GX-M001 （Jiangchao） with high resistance to Orseolia oryzae （Wood-Mason） was used to hybrid with the known resistance cultivars ＂Kangwenqingzhan＂ （harboring GM5 gene）, OB677（ harboring GM3 gene） from Sri Lanka, HT1350 and high yield end quality cultivar ＂ Guiruanzhan＂. [ Result] Through pyramiding the multi-resistant genes via routine hybridization, the general resistances of the hybrids were remarkably enhanced. The grades of resistance were also improved, many of the combinations were endowed with a resistance at immune level （grade 0） ; and interestingly, the respective hybridization of GX-M001 （high resistance） with OB677（ medium resistance） and HT1350（suscepti- ble） also generate two lines at immune level, which is probably the effects of additive effects of genes.[ Conclusion] By routine hybridization, multiple genes were successfully pyramided, thus generating novel rice lines with multiple resistances. For the rice breeding scientists at the grass-roots level, the resistance-resistance pyramiding is an effective approach to breed high resistance cultivars.展开更多

Diagnosis of the new genus Tegosecans gen. nov. is that body spindle- shaped, scapular setae ahead of rear shield margin; opisthosoma of smooth dorsal and microtuberculate ventral annuli, dorsal annuli with central longitudinal ridge ending before lateral median ridges; second dorsal annulus broader, covering the next 2 annuli, 3–4 dorsal annuli with lateral lobes. The 10 new species are Trisetacus fortunei sp. nov., Glyptacus kweilinensus sp. nov., Neoacaphyllisa phaeosticta sp. nov., Oxycenus tomentosae sp. nov., Phyllocoptacus fortuneir sp. nov., Tegosecans jinxiuensis gen. nov. ＆ sp. nov., Epitrimerus sinensis sp. nov., Phyllocoptes glaucifoliae sp. nov., Diptilomiopus pomiferae sp. nov., and Vimola laxifloris sp. nov.. All of these new species are on the undersurface of leaves and cause no apparent damage to the host plants.展开更多
