The relationship between pests and natural enemies using multivariate analysis on cotton in different spacing has not been documented yet. Using multivariate approaches is possible to optimize strategies to control Aphis gossypii at different crop spacings because the possibility of a better use of the aphid sampling strategies as well as the conservation and release of its natural enemies. The...
wolbachia is an obligatory, intracellular α-proteobacterium which infect the reproductive and somatic tissues of some arthropod and nematode populations. because there are not any available data on the presence of this bacterium in iran, the present study was done to determine the presence of this bacterium among 30 species of arthropods and nematodes. after dna extraction from samples, we scre...
Diptera are among the most serious arthropod pests affecting mushroom crops. Phorid flies, especially Megaselia halterata, have traditionally been globally considered as a minor pest, although they very important problem on Spanish farms. The concerns with respect to phorid fly populations recently increased, notably jumping from being major pest in India, UK and USA, where yield losses ranging...
Use of elemental markers to study movement of arthropod pests of field crops is reviewed. Trace elements, rubidium (Rb) and cesium (Cs), have provided a nondisruptive method of marking natural adult populations via developmental stage consumption of treated host plants. Multigenerational marking occurs with the transfer of elemental markers from marked adults to reproductive products, including...
The data we present are part of the CUARENTAGRI project, which involves all archipelagos Macaronesia (Azores, Madeira, Canary Islands and Cabo Verde). project aims to: i) identify evaluate risks associated with introduction new arthropod pests; ii) study population dynamics selected pest species currently responsible for damage key target crops iii) develop monitoring systems, based on predicti...
We report here genome sequences and comparative analyses of three closely related parasitoid wasps: Nasonia vitripennis, N. giraulti, and N. longicornis. Parasitoids are important regulators of arthropod populations, including major agricultural pests and disease vectors, and Nasonia is an emerging genetic model, particularly for evolutionary and developmental genetics. Key findings include the...
The use of synthetic insecticides in agriculture over the years has resulted in the development of resistance in insect pest populations and environmental problems. Therefore, it is highly desirable to develop new selective insecticidal agents based on natural products. Piperidine alkaloids occur widely in plants as well as in the animal kingdom. Due to their great diversity in biological and p...
Integrated Vector Management (IVM) strategies are intended to protect communities from pathogen transmission by arthropods. These strategies target multiple vectors and different ecological and socioeconomic settings, but the aggregate benefits of IVM are limited by the narrow focus of its approach; IVM strategies aim only to control arthropod vectors. We argue that IVM should encompass environ...
Over the last decade, remote sensing technologies and geographical information systems have moved from the research arena into the hands of vector control specialists. This review explains remote sensing approaches and spatial information technologies used for investigations of arthropod pests and vectors of diseases affecting humans and livestock. Relevant applications are summarized with exam...
