| 外来入侵性害虫番茄潜叶蛾 Tuta absoluta (Meyrick)于2018年3月26日在云南弥渡县被发现，为明确其发生为害情况，筛选出有效的防治药剂，阻止该虫的发生和蔓延，本研究采用性诱剂进行田间调查分析了番茄潜叶蛾的发生情况，通过田间药效试验比较噻虫嗪、噻虫胺、虫螨腈、苏云菌杆菌、乙基多杀菌素、阿维·氯虫苯甲酰胺、噻虫·高氯氟和阿维·灭蝇胺对番茄潜叶蛾的防治效果。调查结果表明该虫在番茄种植区域均有发生，大棚番茄地发生尤其严重，为害株达100%，百叶幼虫量55.00~101.67头/百叶，周诱蛾量4.70~61.20头/板，果子的为害率达19.33%，最高达40%。田间药效的结果表明：33%阿维·灭蝇胺SC防效较好，药后3 d防效达74.30%，其次30%虫螨腈SC、6%阿维·氯虫苯甲酰胺SC和6%乙基多杀菌素SC药后3 d防效64.25%、67.98%、54.85%，药后5 d防效79.08%、79.00%、73.45%，药后7 d防效81.60%、80.45%、65.70%。结果表明番茄潜叶蛾在弥渡县大棚发生为害较为严重，性诱剂对成虫有良好的诱集效果，虫螨腈、阿维·氯虫苯甲酰胺、乙基多杀菌素和阿维·灭蝇胺可作为幼虫的防治药剂。 |

| The tomato leafminer, Tuta absoluta (Meyrick)was found in tomato greenhouses in Midu, Yunnan Province on March 26, 2018, which was an alien invasive pest. It was urgent to take effective measures to prevent the occurrence and spread of the pest. In this paper, field investigation was conducted to analyze the occurrence of T. absoluta using sex phermone. And the control effect of chemical pesticides was tested in field, including thiamethoxam, clothianidin, chlorfenapyr, BT, spinetoram, abamectin-chlorantraniliprole, thiamethoxam-cyfluthrin and abamectin-cyromazine. The result showed that T.absoluta occurred in most tomato planting areas especially in greenhouse, with damage rate of 100%. The larvae number was 55.00~101.67 per 100 leaves. The number of moths was 4.70~61.20 on one plate per week. The damage rate to fruit was 19.33% with the highest of 40% in harvest period. The pesticide field trials showed that 33% abamectin-cyromazine SC had the higher control effect, with 74.30% after 3 days. The next were 30% chlorfenapyr SC, 6% abamectin-chlorantraniliprole SC and 6% spinetoram SC. The control effects were 64.25%, 67.98%, 54.85% after 3 days, 79.08%, 79.00%, 73.45% after 5 days and 81.60%, 80.45%, 65.70% after 7 days. Overall, T.absoluta damaged seriously in greenhouse in Midu, Yunnan Province. The sex attractant pheromone was effective to attract the adult. chlorfenapyr, abamectin-cyromazine and spinetoram could be used to control T. absoluta. |
