【摘要】 阳茎戟瘿蚊（HastatomyiahastiphallaYangetLuo）是国内外首次报道的果害虫，在广州每年发生7~8代，以蛹在土中越冬。秋季气温25~30℃、相对湿度70％~90％，卵期2~3天，幼虫期4~6天，前蛹期4~10天，蛹期6~10天，成虫期1~1．5天。成虫在果嫩叶产卵，幼虫孵出后随即侵入叶肉并逐渐发育形成疱状突起的虫瘿，通常一叶多瘿。幼虫老熟后自行离瘿入土化蛹。描述了各期虫态的形态特征，报道了主要的生物学特性和发生规律。更多还原

【Abstract】 Among the pests mango,this mango gall midge (Hastatomyia hastiphlla Yang et Luo) is reported for first time in entomological literature. It occurred in the area of Guangzhou with 7-8 generations per year. It overwintered at pupa stage in soil. During autumn when the temperature reached 25 ~ 30℃with the relative humidity of 70% ~ 90%, the egg stage lasted 2~3days; larva stage, 4 ~6 days; prepupa stage, 4~ 10days; pupa stage, 6 ~10days, and the adult stage, 1 ~1. 5days. Eggs are laid on the young leaves of mango. After being hatched the larva penetrated into the leaf blade and developed a protuberance forming the gall. Usually many galls are formed in a single leaf. As the larva matured, it deserte the leaf, fall the soil and pupate in soil. The present paper describes the morphological characteristics of various stages of the gall midge, its growing habits, its life cycle, and the laws of its development.更多还原
