“…avermectins and milbemycins) and formamidines (George et al, 2004;Abbas et al, 2014). Other targets of acaricides includes proteins involved in the respiratory chain and chemicals developed to date that target this process include Diafenthiuron, Chlorfenapyr, Acequinocyl, Fenazaquin and Cyenopyrafen (Ruder and Kayser, 1993;Nauen and Bretschneider, 2002;Raghavendra et al, 2011;Van Leeuwen et al, 2014). A prime example is the vacuolar ATPase that has shown promise as an insecticidal target for inhibitory compounds such as the pea albumin 1b (PA1b) protein, with activity in several pest species including the cereal weevil and mosquitoes (Gressent et al, 2007(Gressent et al, , 2011Huss and Wieczorek, 2009;Muench et al, 2014).…”

Managing the spread and load of pathogen-transmitting ticks is an important task worldwide. The cattle tick, Rhipicephalus microplus, not only impacts the economy through losses in dairy and meat production, but also raises concerns for human health in regards to the potential of certain transmitted pathogens becoming zoonotic. However, novel strategies to control R. microplus are hindered by lack of understanding tick biology and the discovery of suitable vaccine or acaricide targets. The importance of transmembrane proteins as vaccine targets are well known, as is the case in tick vaccines with Bm86 as antigen. In this study, we describe the localization and functional annotation of 878 putative transmembrane proteins. Thirty proteins could be confirmed in the R. microplus gut using LC-MS/MS analysis and their roles in tick biology are discussed. To the best of our knowledge, 19 targets have not been reported before in any proteomics study in various tick species and the possibility of using the identified proteins as targets for tick control are discussed. Although tissue expression of identified putative proteins through expansive proteomics is necessary, this study demonstrates the possibility of using bioinformatics for the identification of targets for further evaluation in tick control strategies.

“…The annual expenditure on acaricides to control red and black flat mites has been approximately US$ 70 million, a figure that emphasizes the economic importance of controlling this disease and its vector and the need for better integrated pest management strategies (YAMAMOTO et al, 2005). Rational control strategies have becoming a matter of great concern, particularly with respect to resistance development to acaricides, since some compounds have been used for more than 30 years (LEEuWEN et al, 2015).…”

SPATIAL DISTRIBUTION AND SEQUENTIAL SAMPLING OF Brevipalpus phoenicis IN CITRUS

et al. 2016

ABSTRACT-Among the pests of citrus, one of the most important is the red and black flat mite Brevipalpus phoenicis (Geijskes), which transmits the Citrus leprosis virus C (CiLv-C). When a rational pest control plan is adopted, it is important to determine the correct timing for carrying out the control plan. Making this decision demands constant follow-up of the culture through periodic sampling where knowledge about the spatial distribution of the pest is a fundamental part to improve sampling and control decisions. The objective of this work was to study the spatial distribution pattern and build a sequential sampling plan for the pest. The data used were gathered from two blocks of valencia sweet orange on a farm in São Paulo State, Brazil, by 40 inspectors trained for the data collection. The following aggregation indices were calculated: variance/ mean ratio, Morisita index, Green's coefficient, and k parameter of the negative binomial distribution. The data were tested for fit with Poisson and negative binomial distributions using the chi-square goodness of fit test. The sequential sampling was developed using Wald's Sequential Probability Ratio Test and validated through simulations. We concluded that the spatial distribution of B. phoenicis is aggregated, its behavior best fitted to the negative binomial distribution and we built and validated a sequential sampling plan for control decision-making. Index terms: red and black flat mite, negative binomial, Poisson distribution, decision making, integrated pest management. DISTRIBUIÇÃO ESPACIAL E AMOSTRAGEM SEQUENCIAL DE Brevipalpus phoenicis EM CITRUSRESUMO-Dentre as pragas dos citros, uma das mais importantes é o ácaro da leprose Brevipalpus phoenicis (Geijskes), que transmite o vírus da leprose dos citros (CiLv-C). Quando um plano racional de controle de pragas é adotado, é importante se determinar o tempo correto para se dar início ao plano de controle. Para tanto, é necessário acompanhamento constante da cultura através de amostragens periódicas, onde o conhecimento do comportamento espacial da praga é fundamental. O objetivo deste trabalho foi estudar o padrão de distribuição espacial e desenvolver um plano de amostragem sequencial para a praga. Os dados utilizados foram coletados em dois talhões de laranja valência em uma fazenda no estado de São Paulo, Brasil, por 40 inspetores treinados para a atividade.

“…Their high reproductive potential and short generation time allow for a rapid increase in population size and quick development of resistance against insecticides (reviewed in Van Leeuwen et al 2015). If their numbers are not kept below economic damage thresholds, spider mites can pose a serious threat to the production of food and ornamental crops not only by feeding, but also by transmitting various plant pathogens (Jeppson et al 1975).…”

Specialist and generalist predator mites have been recommended against the two-spotted spider mite (Tetranycus urticae) as biological control agents, but their effectiveness in population regulation has been rarely examined under circumstances when prey had the opportunity to express antipredatory responses. We tested the efficiency and preference for prey life stages of three predator mites, one specialist (Phytoseiulus persimilis) and two generalists (Amblyseius swirskii and Iphiseius degenerans). We used two predator densities and performed the experiment under 'seminatural' conditions. We found that significantly less eggs and adult spider mites survived in the presence of P. persimilis compared to the control group, and this predator mite consumed more eggs at high density than the other predators. In the presence of A. swirskii fewer adult spider mites survived at low density compared to the control, whereas egg survival was lower than in the control group at both densities. In the presence of I. degenerans, only the survival of eggs was lower than in the control group and only at high density. Our results suggest that the generalist A. swirskii, but not I. degenerans, may be efficient in regulating prey populations through egg consumption, and, thus, represents an alternative to the effective specialist predator.
