Abstract Currently, there are a total of 15 thrips species in the genus Megalurothrips (Thysanoptera: Thripidae). sjostedti Trybom and usitatus (Bagnall) most economically important pest because serious damage they can do to leguminous crops, especially cowpea, which is an grain crop for Africa vegetable rest world. only distributed Africa, while M. widely spread subtropical tropical regions wo...

BACKGROUND Watermelon silver mottle virus (WSMoV), which belongs to the genus Tospovirus, causes significant loss in Cucurbitaceae plants. OBJECTIVES Development of a highly sensitive and reliable detection method for WSMoV. MATERIALS AND METHODS Recombinant plasmids for targeting the sequence of nucleocapsid protein gene of WSMoV were constructed. SYBR Green I real-time PCR was established...

Amongst the 100 described species worldwide of the genus Scirtothrips, the South African Citrus Thrips, S. aurantii Faure, has been considered unique because the males possess a comb of stout setae on the hind femora (Hoddle & Mound, 2003). A new species that shares this character state is described here from Cedrus (Pinaceae) in Kenya, although no information is available for either species co...

Three new genera and seven new species of fungal-feeding thrips are described from the northern, tropical zone of Australia. Majerthrips barrowi gen. et sp. n. is a large species exhibiting polymorphism associated with wing development and sex, whereas Senithrips psomus gen. et sp. n. is a minute monomorphic species with little sexual dimorphism. Also monomorphic is Jacotia rhodorcha sp.n., the...

Thrips are key pests of mango, Mangifera indica (L.), in Malaysia, including the Northern Peninsular. As Penang has year-round equatorial climate and high of rainfall, the populations of thrips may be subject to variations in composition and size. With a goal of developing an appropriate control strategy, a survey was conducted in Penang to determine species composition and abundance in relati...

BACKGROUND The efficacy of systemic applications of imidacloprid for the management of avocado thrips and avocado lace bug was determined in field trials. Following insecticide treatment by chemigation, leaves of appropriate age for each insect were sampled over a 6 month period and used for bioassays. Imidacloprid residues were measured by ELISA in leaves used for bioassays to determine concen...

Plant defenses inducible by herbivorous arthropods can determine performance of subsequent feeding herbivores. We investigated how infestation of tomato (Solanum lycopersicum) plants with the Western flower thrips (Frankliniella occidentalis) alters host plant suitability and foraging decisions of their conspecifics. We explored the role of delayed-induced jasmonic acid (JA)-mediated plant defe...

Citrus thrips, Scirtothrips citri (Moulton), is a plant-feeding pest most widely recognized for causing damage to citrus and mango fruits. This insect has broadened its host range to become a significant pest of commercial blueberries grown in the San Joaquin Valley of California. We evaluated Beauveria bassiana (Balsamo) for control of citrus thrips in blueberries grown under two watering regi...

Caliothrips phaseoli, a phytophagous insect, detects and responds to solar ultraviolet-B radiation (UV-B; lambda <or= 315 nm) under field conditions. A highly specific mechanism must be present in the thrips visual system in order to detect this narrow band of solar radiation, which is at least 30 times less abundant than the UV-A (315-400 nm), to which many insects are sensitive. We constructe...
