从产地引入象甲，研究它在高海拔低纬度———昆明的生活习性，经安全性、适应性、控制效果的试验研究，证实水葫芦象甲对２３个科、４６种植物不产生危害，只取食水葫芦，是单食性昆虫。象甲对水葫芦重量控制率平均为５４．３％，株高控制率为４２４％，根长控制率为１９２％，叶片控制率为１０６％，植株分蘖控制率达３２％。象甲在昆明具有良好的生物学适应性。对控制滇池水葫芦疯长，恢复生物多样性、保持生态平衡具有重要价值。 Introduced from the origin of Xiangjia, to study it in the high latitudes of low latitude - the living habits of Kunming, the safety, adaptability, control effects of experimental studies confirmed that water hyacinth weevil on 23 families, 46 kinds of plants do not produce harm , Only eat water hyacinth, is a simplex insect. The average weight control rate of Xianggui water hyacinth was 54.3%, the plant height control rate was 424%, the root length control rate was 192%, the leaf control rate was 106% and the plant tiller control rate was 32 %. Elephant A has a good biological adaptability in Kunming. It is of great value to control the soaring of the water hyacinth in Dianchi Lake, restoring the biological diversity and maintaining the ecological balance.
