摘要

受巴西联邦法律保护的巴西核桃科(malpiighiales: carcaraceae)树木是许多社区的主要收入来源。塞拉多(稀树草原生物群系)向放牧或农业地区的转变已经将这些树种隔离在农业-城市景观中。在塞拉多、牧场和城市三种不同环境下，研究了环境多样性对巴西杉树瘿虫群落丰度的影响。城市地区巴西蜂小叶上有较多的银茧蜂(膜翅目:银茧蜂科)成虫及其瘿、其寄生蜂甜蝇(膜翅目:银茧蜂科)和捕食者蜜蚜(半翅目:红茧蜂科)。全腐叶率(表现出各种腐叶)与乔木数呈负相关。更大的生境多样性有利于昆虫物种及其天敌。

Does environmental diversity affect hymenopteran galling insects and their natural enemies on Caryocar brasiliense trees (Caryocaraceae)?

Caryocar brasiliense (Malpighiales: Caryocaraceae) trees, protected by Brazilian federal laws, are the main income source in many communities. The transformation of the Cerrado (savanna biome) into grazing or agricultural areas has been isolating these trees species in an agro-urban landscape. We studied the effects of environmental diversity on the abundance of galling insect communities inhabiting C. brasiliense trees in three different environments: Cerrado, pasture, and an urban area. Eurytoma sp. (Hymenoptera: Eurytomidae) adults and their galls, its parasitoid Sycophila sp. (Hymenoptera: Eurytomidae) and the predator Zelus armillatus (Hemiptera: Reduviidae) were present in larger numbers on the C. brasiliense leaflets in the urban area. The percentages of totally galled leaflets (exhibiting all kinds of galls) and the number of trees were negatively correlated. Greater habitat diversity favored that of galling insect species and their natural enemies.
