金柑芽瘿蚊属双翅目瘿蚊科(种名待定),是我区金柑上的一种新的重要害虫。广西金柑主要产区融安、阳朔两县均有发生。据调查,阳朔县各金柑园春梢被害率达19.5—81.2％,春梢芽被害率一般在9％左右,严重时可达50～60％。金柑芽瘿蚊成虫产卵于春梢腋芽内,孵化后幼虫潜于芽内生长为害,刺激腋芽膨大,形成虫瘿,致使嫩芽不能抽发春梢,不能开花,直接影响产量;少数虫瘿旁可以抽出纤弱晚春梢或夏梢,但均不能开花着果。为此,我们于1980～1985年对其生活习性进行了接种饲养、田间调查等初步研究,现简报如下。
Grifola frondosae Dipteroptera mosquito family (to be determined), is a new important insect on my kumquat. Guangxi kumquat main producing areas Rongan, Yangshuo counties have occurred. According to the survey, Yangshuo County, Kumquat spring shoots rate of 19.5-81.2% spring shoots bud damage rate is generally about 9%, severe up to 50 to 60%. Gypsophila melanogaster adult spawn in spring shoots axillary buds, the larvae hatch after the potential growth in the shoot damage, stimulate axillary buds swollen, the formation of galls, resulting in buds can not spring buds, can not flowering, a direct impact on production; a few insects 瘿Next to the weak late spring or summer tip can be extracted, but can not blossom fruit. To this end, we conducted a preliminary study of their living habits from 1980 to 1985, field surveys, are summarized below.
