Heterorhabditis amazonensis n. sp. (Rhabditida: Heterorhabditidae) from Amazonas, Brazil
In a survey of entomopathogenic nematodes in Brazil, a nematode isolate of the genus Heterorhabditis was found. The nematode was collected from soil by the insect-baiting technique and maintained in the laboratory on last instar Galleria mellonella (L.) larvae. Morphological and molecular studies of the isolate showed that the nematode is a new species. Light and scanning electron microscopy, D...
متن کاملAcaricide resistance mechanisms in Rhipicephalus (Boophilus) microplus Mecanismos de resistência aos acaricidas em Rhipicephalus (Boophilus) microplus
Acaricide resistance has become widespread in countries where cattle ticks, Rhipicephalus (Boophilus) microplus, are a problem. Resistance arises through genetic changes in a cattle tick population that causes modifications to the target site, increased metabolism or sequestration of the acaricide, or reduced ability of the acaricide to penetrate through the outer protective layers of the tick’...
متن کاملBiological Parameters of Rhipicephalus (Boophilus) microplus (Acari: Ixodidae) Fed on Rabbits, Sheep, and Cattle
In order to determine the effect of various hosts on feeding performance of Rhipicephalus (Boophilus) microplus, we used 3 mammalian species as hosts, cattle (Qinchuan), sheep (T an), and rabbits (Japanese white rabbit) for infest-ing ticks. Five hundreds of R. microplus larvae were exposed to each animal (3 animals/host species). Tick recoveries were 11.0%, 0.47%, and 5.5% from cattle, sheep, ...
متن کاملSusceptibility of Rhipicephalus (Boophilus) microplus (Acari: Ixodidae) to pyrethroids and their associations in Pernambuco, Brazil.
The synthetic pyrethroids and their associations have been widely used for controlling Rhipicephalus (Boophilus) microplus. The frequent use of acaricides has been inducing the development of resistance in the tick populations. The aim of this study was to assess the susceptibility of R. (B.) microplus populations to pyrethroids and their associations in the region of Garanhuns, Pernambuco, Bra...
متن کاملEffects of destruxin A on Rhipicephalus (Boophilus) microplus ticks (Acari: Ixodidae).
This study evaluated the effects of destruxin A on Rhipicephalus (Boophilus) microplus females, since this toxin is one of the likely causes of high mortality induced by the entomopathogenic fungus Metarhizium anisopliae in arthropods. Ticks were immersed or inoculated with different concentrations of destruxin A. Despite the doses applied, there were no deaths or significant alterations in ovi...
