据印度喀拉拉农学院昆虫学系报道,在印度,首次注意到茄子瘤缘蝽(Acan thocoris scabrator Fabr.)为害杧果果实。1976年9月,在特里凡得朗发现它为害杧果果实。中国曾报道在广州茄子瘤缘蝽为害灯笼果、辣椒、茄子和简瓜等;马来西亚曾报道它为害Salanaceae和旋花科的植物。茄子瘤缘蝽的成虫深褐色,长1.4厘米,宽5毫米。它食杧果嫩果,刺穿果皮,吸吮果汁。浸害点渗出分泌物,各点周围的果皮颜色变深,继之因微生物侵染而果实腐烂,致落果。该虫在印度旋花植物上繁育,在叶片和蔓上产卵,一次产18—20个,卵呈旋花种子状。若虫初呈浅红色,其后变成浅绿和浅棕色,具群居性,取食旋花蔓。蛹期主要在10—11月,持续70—75天,现正在进行其生物学的详细研究。
According to the Department of Entomology at Kerala College of Agriculture in India, it is the first time in India that Acan thocoris scabrator Fabr. In September 1976, it was found in Trivandrum as a fruit of mangosteen. In China, it has been reported that Phylloscopus spp., Aphid in Hong Kong, has been reported to cause damage to crab fruits, pepper, eggplant and janitor, while it has been reported in Malaysia as a plant infecting Salanaceae and Convolvulaceae. Eggplant knobby bug adult dark brown, 1.4 cm long and 5 mm wide. It is fresh fruit Nong Nong, piercing the peel, sucking juice. Bleeding point exudation secretions, dark spots around the peel color, followed by microbial infection and fruit decay, fruiting results. The insect breeding in India convolvulus, spawning in the leaves and vine, a production of 18-20, the egg was convolvulus seed. The nymphs initially showed a light red color and later became light green and light brown with gregarious feeding on the convolvuli. The pupal stage is mainly in October-November, lasts for 70-75 days. Now its biology is undergoing detailed research.
