1、黄条跳(Phyllotreta vittata F.)广布全国和世界各地。食性复杂。在广州郊区是十字花科首要害虫,严重威脅蔬菜生产。2、敌百虫对黄条跳(虫甲)成虫,具有特效作用。使用0.05%的有效成分,在24小时内,成虫死亡情况,室内达99.1%以上;田間施用后,虫口密度大减,6株以上的植株才有一个虫子。最少的竟达30株以上才能找到一个虫子。DDT乳剂杀成虫效果,在48小时,最高不超过33%。使用敌百虫来防治黄条跳(虫甲),較现在广州郊区一般用药成本低了3倍以上,且使用簡便,对人畜安存。10%666乳剂与对照无差别。效果不良。DDT煤油液(1:600——800)防治幼虫較好,对植物无害。DDT乳剂(1:100)亦有一定效果,但成本高些。3、使用化学药剂防治黄条跳(虫甲),必須采取噴药杀成虫,淋药治幼虫或土壤消毒同时并进。抓紧关鍵时期。寻找适当药剂及改善使用方法,可以提高防治效果。4、积极找出适用于蔬菜害虫的土农药,在生产实践上将有极大意义。这是蔬菜害虫化学防治的一条新途径。
1, Phyllotreta vittata F. Widely spread throughout the country and around the world. Complex diet. In the suburbs of Guangzhou is the crucifer major pests, a serious threat to vegetable production. 2, trichlorfon on the yellow strip (insect) adults, with special effects. With 0.05% active ingredient, the death rate of adult worms within 24 hours was above 99.1% indoors. After field application, the density of insect population was greatly reduced and only one insect was found in more than 6 plants. As few as 30 or more to find a bug. DDT emulsion kill adult effect, in 48 hours, up to 33%. The use of trichlorfon to control the yellow strip jump (pest), compared with the current cost of the general drug suburb in Guangzhou 3 times lower, and easy to use, safe for humans and animals. 10% 666 emulsion and control no difference. Bad effect. DDT kerosene liquid (1: 600 - 800) is better control of larvae, harmless to plants. DDT emulsion (1: 100) also has a certain effect, but the cost is higher. 3, the use of chemicals to prevent the yellow strip jump (pest), you must take the spray to kill adults, treatment of larvae or soil disinfection at the same time. Pay close attention to the critical period. Looking for appropriate agents and improve the use of methods, can improve the control effect. 4, actively identify the soil pesticides for vegetable pests, in the production of practice will be of great significance. This is a new way of chemical control of vegetable pests.
