自2009年以来,非洲吉布提芒果树上暴发壮铗普瘿蚊.针对壮铗普瘿蚊在吉布提的发生、危害、部分生物学特性和化学防治进行初步研究.在吉布提,壮铗普瘿蚊发生最严重的地区为Damerjog的总统农场和Alisabieh的Wea将军农场.壮铗普瘿蚊以虫瘿寄生芒果叶片,造成叶片卷缩、变形,影响光合作用和植物的生长.该虫在吉布提1a发生6代,一个世代(45±2)d.在热季5月份温度达到40℃时,以幼虫和蛹在虫瘿里休眠.乐斯本1 000倍+有机硅、三氟氯氰菊酯1 000倍+有机硅混合液对壮铗普瘿蚊的室内防效分别为93.33%和95.87%,但其在果园对壮铗普瘿蚊的防效分别为50.17%、38.25%,远低于室内防效.
The occurrence, harm, partial biological characteristics and chemical control of Chlamydomonas reinhardtii in Djibouti have been preliminary studied since the outbreak of the malaria mosquito in the mangrove tree of Djibouti in Africa since 2009. In Djibouti, The worst areas are the President’s Farm in Damerjog and General Wea’s farm in Alisabieh, which infest mango leaves with insects, causing the leaves to curl, distort and affect photosynthesis and plant growth. The bug occurred in Djibouti 1a Generation, one generation (45 ± 2) days d. Litter and pupae dormancy in larvae and pupae at temperatures up to 40 ° C in hot season in May. Rexcomb 1000 times + silicone, cyhalothrin 1000 times + organic The indoor control effect of the mixture on the mosquito was 93.33% and 95.87%, respectively. However, the control effects on the mosquito in the orchard were 50.17% and 38.25% respectively, much lower than the indoor control effect.
