利用低温处理方法 ,可以杀死接入芦柑鲜果中桔小实蝇Bactrocera(Bactrocera)dorsalisHendel的卵和幼虫。经试验 ,3龄幼虫对低温处理的忍耐力比卵和 1～ 2龄幼虫都强 ,且在 1 7～ 1 9℃的处理温度下处理 1 2天后死亡率达 1 0 0 %。人工接入 64 92 5头和自然产卵果 3 0 0个培养获得 62 58头的 3龄幼虫在 1 7～ 1 9℃温度下处理 1 2天 ,所有幼虫全部死亡。果实损伤测定试验表明 ,在此处理条件下 ,对芦柑鲜果不会造成损害
Using low-temperature treatment, the eggs and larvae of Bactrocera (Bactrocera) dorsalisHendel can be killed in fresh citrus fruits. The results showed that the 3rd instar larvae were more tolerant to hypothermia than eggs and 1st to 2nd instar larvae, and the mortality rate reached 100% after 12 days of treatment at the temperature of 17 to 19 ℃. Artificial access 64 92 5 heads and natural spawning fruit 300 cultivars 62 58 3rd instar larvae were treated for 12 days at a temperature of 17 to 19 ° C, and all the larvae died. Fruit injury test showed that, under the conditions of this treatment, Citrus fresh fruit will not cause damage
