Parasite-mediated apparent competition occurs when one species affects another through the action of a shared parasite. One way of controlling the parasite in the more susceptible host is to manage the reservoir host. Culling can cause issues in terms of ethics and biodiversity impacts, therefore we ask: can treating, as compared to culling, a wildlife host protect a target species from the sha...

ChlorobenziIate--ethyl p, p’dichlorobenzilate-offers certain advantages in citrus pest control: it has a very low toxicity to warm-blooded animals which places it in the same category as Ovotran and Aramite; its application does not seriously affect insect parasites and predators or bees. Chlorobenzilate has a low order of toxicity to insects, therefore applications do not control populations o...

We studied the contamination level of the acaricides Folbex VA (bromopropylate, BP), Perizin (coumaphos, CM) Apistan (fluvalinate, FV) and Bayvarol (flumethrine, FM) in brood combs, sugar feed, honey and in new beeswax. All samples were analysed by gas chromatography with ECD detection. After one normal acaricide treatment, in autumn, the brood comb wax was contaminated by all these acaraicides...

Acaricide resistance in Boophilus microplus has been studied for the last 20 years from the toxicology, metabolic and genomic points of view, however, only few methods for molecular detection of resistance have been developed. Despite the relatively poor sensitivity for resistance detection, bioassays remain the method of choice for susceptibility evaluation of tick populations, based on their ...

Dairy cattle farming is of great economic and social importance in all Brazilian's regions. Parasites can reduce milk productivity, especially the tick Rhipicephalus (Boophilus) microplus. This study consisted of a questionnaire answered by 40 milk producers in the northwestern region of the State of São Paulo. The aim was to ascertain how these producers controlled ticks and other parasites. V...
