摘　　要： 报道了不同防治措施对荔枝果园蜘蛛类群的影响,结果表明,不同防治措施对蜘蛛类群影响的差异是明显的,仅使用微生物杀虫剂的生防区蜘蛛类群数量与对照区无显著性差异;应用几丁质合成抑制剂为主的协防区的蜘蛛类群数量上虽较对照区有显著性减少,但其蜘蛛类群的数量仍较化学防治区明显丰富,而应用以广谱性化学农药为主的化学防治区的蜘蛛类群的数量最少,其数量仅为对照区的1/3左右。 The effects of different control measures on spider group in litchi orchard were studied in this papre.The results showed that the difference among effcets of different control measures on spider group in litchi orchard was significant.The quantity of spiders in the Biocontrol area which only microbiological insecticides were used was no difference from the quantity of spiders in naturalcontrol area;the quantity of spiders in the coordinatedcontrol area which such as chitin synthetic inhibitor were mainly used decreased significantly comparing to the quantity of spiders in naturalcontrol area,but was much richer than in chemicalcontrol area which widespectrum chemical insecticides were mainly used;the quantity of spiders in chemicalcontrol area was least,was about 1/3 of the quantity of spiders in naturalcontrol area.
