脐橙昆虫种类和物种个体数随树龄的增加而增加,昆虫群落因脐橙树龄的演变而演替。不同防治措施对昆虫群落的影响很大。自然园和综防园的昆虫种类相同,但群落内物种个体数比综防园集中。化防回昆虫种类少,群落内物种个体数最集中,优势度突出。
The number of navel orange species and the number of individuals increased with the increase of tree age, and the succession of the insect community was due to the evolution of navel orange tree age. Different control measures have a great influence on insect communities. The natural insects in the Nature Park and the Integrated Prevention Park are the same, but the number of individual species in the community is more concentrated than in the general prevention park. The number of anti-back insects less species within the community the most concentrated species, dominance prominent.
