我省仁果类果树主要是梨、苹果、花红、海棠等。据不完全调查,目前省内已知为害仁果类果树的叶蝉有10种,其中尤以苹果黄叶蝉、苹小塔叶蝉、小绿叶蝉为害最烈。果树从幼苗到成株期,屡遭叶蝉为害,其成、若虫均可刺吸果树汁液,被害叶片正面常呈现退色斑点,严重时斑点连成片,致使全叶发白、变黄、枯焦,提早落叶,影响树势,降低产量和产值;而成虫多在嫩梢和叶脉组织内产卵,产卵过程中往往切断果树输导组织,影响养分运输,导致水分大量蒸发。因此,在一些仁果类果树产区,叶蝉的为害已成为果树生长的一大障碍。为有利对仁果类果树叶蝉的研究,现将近几年的调查资料整理成文,供参考。 Pome fruit trees in our province are mainly pear, apple, bonus, Begonia and so on. According to incomplete surveys, there are currently 10 species of leafhoppers in the province that are known to have harmed pome fruit trees, most notably the apple leafhopper, the apple leafhopper and the green leafhopper. Fruit trees from the seedlings to adult stage, repeated damage by leafhoppers, its into, nymphs can suck fruit juice, the front of the leaves are often fading spots, severe spots even into pieces, resulting in whole leaves whitish, yellow, Kujiao , Early deciduous, affecting the tree vigor and reduce the yield and output; and adult more in shoots and vein tissue spawning, oviposition tend to cut off the fruit tissue, affecting nutrient transport, resulting in a large amount of water evaporation. Therefore, in some pome fruit producing areas, the damage of leafhoppers has become a major obstacle to the growth of fruit trees. For the benefit of pome fruit tree leafhopper research, the investigation data in recent years are collated for reference.
