Effects of temperature on the development and population growth of the melon thrips, Thrips palmi, on eggplant, Solanum melongena. [PDF]

J Insect Sci, 2014
The effects of temperature on the melon thrips, Thrips palmi Karny (Thysanoptera: Thripidae), preimaginal development, survival, fecundity, longevity of females and males, and population growth were investigated at 16, 19, 22, 25, 28, and 31° C, 70-80% RH, and a photoperiod of 12:12 L:D. The results indicated that the duration of egg, larval, and pupal

First report on honeydew excretion by the melon thrips, Thrips palmi karny (Thysanoptera : Thripidae) and its biochemical analysis

Journal of Horticultural Sciences, 2020
Sap sucking insects like thrips, aphids, mealybugs, whiteflies exploit the sugar rich phloem for growth and development. The excess sugar in the phloem sap creates osmotic imbalance leading to loss of water from haemolymph to gut lumen.

Insecticides outweigh rye cover crop in triggering secondary pest outbreaks. [PDF]

Pest Manag Sci
Insecticides outweigh rye cover crop in triggering secondary pest outbreaks. Zeus Mateos‐Fierro*, Ashley Leach, Ian Kaplan. Spider mite and melon aphid outbreaks are enhanced with broad‐spectrum insecticides, while natural enemies are reduced. However, rye cover crop has little effect on either pest or natural enemy populations.

Progression of Watermelon Bud Necrosis Virus Infection in Its Vector, Thrips palmi

Cells, 2021
Thrips are important pests of agricultural, horticultural, and forest crops worldwide. In addition to direct damages caused by feeding, several thrips species can transmit diverse tospoviruses. The present understanding of thrips–tospovirus relationships

Transmission mode of watermelon silver mottle virus by Thrips palmi.

PLoS ONE, 2021
Thrips and thrips-transmitted tospoviruses cause significant losses in crop yields worldwide. The melon thrips (Thrips palmi) is not only a pest of cucurbit crops, but also a vector that transmits tospoviruses, such as the watermelon silver mottle virus (

Development of a Polymerase Spiral Reaction-Based Isothermal Assay for Rapid Identification of Thrips palmi

Frontiers in Molecular Biosciences, 2022
Thrips cause considerable economic losses to a wide range of food, feed, and forest crops. They also transmit several plant viruses. Being cryptic, it is often difficult to distinguish thrips species in crops and large consignments by conventional ...
