柑桔大实蝇和蜜柑大实蝇是国内外重要的检疫对象,过去仅知柑桔大实蝇在我省分布普遍而且为害比较严重。我们于一九八四年十月至十一月中旬在罗甸六个区和毕节清水铺区进行柑桔害虫调查时,发现了两县均有蜜柑大实蝇,在甜橙上的危害也很严重。如罗甸八茂的42个甜橙虫果中有24个被蜜柑大实蝇为害,在毕节清水铺橙满园的柑桔园内,任意拾夏橙落果10个,经检查全部是蜜柑大实蝇的虫果。由于为害柑桔的两种大实蝇是近似种,它们的形态、生物学特性及为害状相似,在实际工作中常被混淆。现将两种大实蝇的区别及防治简介如下,供植物检疫普查参考。 Citrus fruit fly and citrus fruit fly is an important quarantine object at home and abroad, in the past only know citrus Drosophila widespread in our province and more serious damage. When we conducted a citrus pest survey in six districts of Luodian and Shuishipu district in Bijie from October 1984 to mid-November of this year, we found that both of the counties had Satsuma mays Very serious. Twenty-four of the 42 sweet orange fruit fruits of Luodian Qimao are harmed by the orange fruit fly, and in the citrus orchard of Bijie’s water-filled orange garden, 10 summer oranges are randomly picked up. After checking all of them, Fruit fly fruit insect. As the two species of fruit-flies that attack citrus are similar species, their morphology, biological characteristics, and similarities are often confused in their practical work. Now the difference between the two Dorsal flies and prevention are as follows, for the census of plant quarantine reference.
