Insecticide resistance in onion thrips (Thrips tabaci) (Thysanoptera: Thripidae) [PDF]
New Zealand Journal of Crop and Horticultural Science, 2003 Abstract Onion thrips from onion (Allium cepa) crops were tested for resistance to four insecticides (deltamethrin, diazinon, dichlorvos, and endosulfan) following reports of failure of insecticides to control onion thrips in the field. Bioassays to determine baseline concentration‐mortality responses used thrips from two insecticide susceptible ...

Evaluation of entomophathogenic fungi against onion thrips, Thrips tabaci (Lindeman)
INTERNATIONAL JOURNAL OF PLANT PROTECTION, 2016 Different entophathogenic fungi were evaluated in field trials at the instructional farm of Agril. Entomology Section, College of Agriculture, Dhule for the management of Onion thrips (Thrips tabaci L.) in onion during late Kharif season of 2014-15. All the treatments were observed to be effective in reducing thrips infestation on onion crop. Among the

Characterization of the dynamic microbiome evolution across thrips species
Insect Science, EarlyView.Comprehensive survey of the microbiome in thrips. The dominant bacterial genera found in thrips include intracellular ones, such as Wolbachia and Spiroplasma, and extracellular ones, including Serratia, Pantoea, and Acinetobacter. We isolated and sequenced high‐quality genomes of two dominant symbionts, Pantoea dispersa and Serratia marcescens.

Entomologia Experimentalis et Applicata, EarlyView.Nymphal development took longer at 25°C than 30°C, and the Greek N. tenuis population developed more slowly than the commercial population. Nymphs clearly preferred E. kuehniella eggs over Artemia sp. cysts when both were offered equally. Egg production increased at 30°C, while female longevity declined.

Quantification of Thrips Damage Using Ilastik and ImageJ Fiji
Bio-Protocol, 2018 Quantification of insect damage is an essential measurement for identifying resistance in plants. In screening for host plant resistance against thrips, the total damaged leaf area is used as a criterion to determine resistance levels. Here we present an
