Acaricide 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 کاملA Semi-Selective Agar Medium to Detect the Presence of Xanthomonas axonopodis pv. malvacearum in Naturally Infected Cotton Seed
A semi-selective agar medium was developed for detection of Xanthomonas axonopodis pv. malvacearum (Xam) in cotton (Gossypium hirsutum) seed. The basic medium was peptone-sucrose-agar (PSA). Criteria for the semi-selective medium were the typical colony characters of Xam and its pathogenicity on cotton. Several systemic fungicides and antibiotics in different concentrations were tested alone or...

Inheritance of resistance to Stemphylium solani and to its phytotoxin in cotton cultivars Leaf blight of cotton (Gossypium hirsutum) caused by Stemphylium solani occurs in several cotton growing areas of Brazil, and causes severe yield losses especially in the State of Paraná. The inheritance of resistance to S. solani and to its phytotoxin was investigated in three cotton cultivars. Crosses in...
متن کاملAnalisando sistemas de classificação na web sob a perspectiva da interação social em comunidades de prática
Social interaction mediated by information technology has been studied from several perspectives over the past years. This paper draws attention to the relevance of classification systems and categories as important mediation artifacts in human-computer interaction. In this sense, classification schemes provide meaning to information and mutual understanding between the parts in an interaction....
متن کاملSeleção de Parceiros em Sistemas Par-a-Par de Vı́deo sob Demanda
In this paper, we evaluate the use of partner selection mechanisms to increase the availability of chunks of interest among peers in peer-to-peer videoon-demand systems. We present the lifetime-based partner selection mechanism and compare it with other similar mechanisms through simulation. We show that the lifetime-based mechanism selects more efficient partners than the other mechanisms and ...
