Abstract

The mite Varroa destructor is one of the most studied parasites in apiculture, and its genotype variation is a key factor for the severity of infestation in bee colonies. Here we report the genetic and reproductive profile of mites from 14 Brazilian states with different geographic and climatic conditions. We performed PCR to amplify a fragment of the COI gene and differentiate the haplotypes using restriction enzymes. The K haplotype was widely prevalent in the studied sites, while the J haplotype was found only in four municipalities. We also observed both haplotypes (J and K) coexisting in the same colony, a fact unprecedented in Brazil. Infestation levels were low (0.33 to 15.3%). The reproductive potential showed wide variation (0 to 1.5), indicating that even with the massive presence of K haplotype, environmental and biotic factors related to Africanized honeybees may be responsible for maintaining the mite under low levels in Brazil.

巴西非洲化蜜蜂的Varroa破坏者：遗传和繁殖概况

灭螨螨是蜂业中研究最多的寄生虫之一，其基因型变异是影响蜂群危害程度的关键因素。本文报道了巴西14个州不同地理和气候条件下螨类的遗传和繁殖特征。我们用PCR扩增了COI基因片段，并用限制性内切酶区分了单倍型。K单倍型在研究地点普遍存在，而J单倍型仅在4个城市发现。我们还观察到两种单倍型(J和K)在同一群体中共存，这在巴西是前所未有的。侵染水平低(0.33 ~ 15.3%)。繁殖潜能差异较大(0 ~ 1.5)，表明即使存在大量K单倍型，与非洲化蜜蜂相关的环境和生物因素可能是使巴西螨保持在低水平的原因。

期刊介绍： SOCIOBIOLOGY publishes high quality articles that significantly contribute to the knowledge of Entomology, with emphasis on social insects. Articles previously submitted to other journals are not accepted. SOCIOBIOLOGY publishes original research papers and invited review articles on all aspects related to the biology, evolution and systematics of social and pre-social insects (Ants, Termites, Bees and Wasps). The journal is currently expanding its scope to incorporate the publication of articles dealing with other arthropods that exhibit sociality. Articles may cover a range of subjects such as ecology, ethology, morphology, population genetics, physiology, toxicology, reproduction, sociobiology, caste differentiation as well as economic impact and pest management.
