猕猴桃是我国特有的藤本植物,果实具有丰富的营养价值,维生素的含量比柑和桔多6—8倍,比苹果和梨多30倍,是国际市场上的新兴水果。然而,猕猴桃,特别是中华猕猴桃Actinidia chinensis Planch,却遭到长胸卷象Iso-labus longicollis Fairmare的为害。1965年,该虫在庐山为害严重,被害株率达100％,植物中部叶片被害率达80—90％,一片赤褐,象火烧一样。近几年来,为了保护猕猴桃,防止长胸卷象的为害,进行了一些观察,初步总结于下: 一、形态特征 成虫 体青蓝色,被覆稀疏而极短茸毛,具有金属光泽,密生小刻点,体长6—8.5毫米(除头部),宽4—5毫米。触角棒状,黑色,11节,第一节膨大,先端3节密生黄色茸毛。 雄虫 触角较短,着生在复眼与喙先端的中部。复眼很大,凸出呈半球形,着生处隆起,两隆起之间有一凹陷,直达吻的先端。吻先端 Kiwifruit is endemic to China. Its fruits are rich in nutritional value. The content of vitamins is 6-8 times more than that of oranges and oranges, 30 times more than that of apples and pears. It is an emerging fruit on the international market. However, Actinidia chinensis Planch, a kiwifruit, especially Actinidia chinensis Planch, was damaged by the long-breeder, Iso-labus longicollis Fairmare. In 1965, the insects were severely damaged in Lushan. The rate of the victim plants was 100%. The rate of the damage in the middle leaves of the plants was 80-90%. A piece of red brown was like a fire. In recent years, in order to protect kiwifruit, to prevent the damage of long-leg curled image, some observations were made and summarized as follows: First, the morphological characteristics Adult body blue-green, covered with sparse and extremely short hair, with a metallic luster, Point, body length 6-8.5 mm (except the head), width 4-5 mm. Antenna stick, black, 11 knots, the first section of the enlargement, the first 3 dense yellow hair. Male antennae shorter, was born in compound eye and beak apex in the middle. Compound eye large, protruding hemispherical, Department of birth bulge, a depression between the two uplift, direct kiss to the front. Kiss the tip
