摘要
为了科学利用频振式杀虫灯防治苎麻Boehmeria nivea(Linn.) Gaudich.害虫,明确苎麻田主要灯诱昆虫种类及其灯下诱集动态,于2012年4月～9月在湖北省咸宁地区进行了苎麻田频振式杀虫灯诱虫试验。结果表明:频振式杀虫灯在苎麻田诱杀害虫4目9科19种,地下害虫种类较多,主要包括金龟子、叩甲、天牛、蝼蛄、拟步甲和地老虎等6类。地下害虫又以金龟子为主,主要有华北大黑鳃金龟、铜绿丽金龟、黑绒鳃金龟、斑喙丽金龟、鲜黄鳃金龟、暗黑鳃金龟等6种。金龟子从4月中旬至9月初均灯下可见,以6～7月为诱集高峰期。主要诱集天敌昆虫为步甲、隐翅甲、寄生蜂和瓢虫等4类,除步甲外,其它3类诱集量相对较小,步甲诱集高峰期为4月下旬至5月上旬。频振式杀虫灯最佳使用时间为6～7月,在此期间诱杀苎麻田金龟子类地下害虫数量大、种类多,且避免大量杀伤天敌昆虫。频振式杀虫灯在苎麻田金龟子类地下害虫预测预报和防治中具有较好的推广应用前景。
In order to control ramie pests and make clear the main light trapping insects and flapping lamp population dynamics in ramie field, trapping experiments by frequoscillation pest - killing lamp in Xianning area were conducted from April to September, 2012. The results indicated that 19 species of pests belong to 9 families, 4 orders were trapped by frequoscillation pest - killing lamp in ramie field, mainly species were under- ground pests, they were Scarabs, Elateroidea, Cerambycidae, Gryllotalpidae, Tenebrionidae, Cutworms, mainly groups was Scarabs. Among Scarabs there were Holotrichia oblita, Anomala corpulenta, Maladera orientalis, Adoretus tenuimaculatus, Metabolus tumidifrons, Holotrichia parallela. Scarabs were trapped from mid - April to early September, the emergence peak was from June to July. The main species of natural enemy insects were Carabidae, Staphilinidae, Coccinellidae and Parasitoid wasp. Tapping number of other 3 groups was relatively small except Carabidae, the emergence peak of Carabidae was from late April to early May. The best time of turning on light was June to July, during this period, underground -pests as scarabs trapped by frequoscillation pest- killing lamp is in large in large number; it would be more promising and control. quantities, variety, and avoid killing natural enemy insects prospects for commercial production in ramie pests forecast
