Acquisition and transmission by an insect vector is central to the infection cycle of the majority of plant pathogenic viruses. Plant viruses can interact with their insect host in a variety of ways including both non-persistent and circulative transmission; in some cases, the latter involves virus replication in cells of the insect host. Replicating viruses can also elicit both innate and spec...

Insect vectors of Leishmaniases, Chagas disease and African trypanosomiasis remain human health, veterinary economic problems worldwide. Several sex pheromones molecules that contribute to mating behavior have been identified in these vectors. These chemical signals are potential alternatives traditional insecticides. This review discusses the diversity pheromone their role insect trypanosomias...

Insect cells have been successfully cultured in vitro as continuous cell lines for over 35 years. The media, culture methodology and conditions have been well resolved such that, for many insects, new cells lines can be routinely developed. Factors that are considered important for developing insect cell cultures are described as well as some of the history that led to the success. One of the m...

Phytoplasmas are insect-transmitted phytopathogenic bacteria that can alter plant morphology and the longevity and reproduction rates and behavior of their insect vectors. There are various examples of animal and plant parasites that alter the host phenotype to attract insect vectors, but it is unclear how these parasites accomplish this. We hypothesized that phytoplasmas produce effectors that...

Persistent plant viruses usually depend on insects for their transmission; they cannot be transmitted between plants or through mechanical inoculation. However, the mechanism by which persistent viruses become pathogenic in insect vectors remains unknown. In this study, we used Rice stripe virus (RSV), its insect vector Laodelphax striatellus and host plant (Oryza sativa) to explore how persist...

leishmaniasis has long been known as a significant public health challenge in many parts of iran. phlebotomus pa­patasi and p. sergent i are the vectors of zoonotic cutaneous leishmaniasis and anthroponotic cutaneous leish­maniasis respectively, and 5 species of sand flies including p. kandelakii , p. neglectus , p. perfiliewi , p. keshishiani and p. alexandri are considered as probable vectors...
