Peptidoglycan recognition proteins (PGRPs) are multifunctional pattern recognition proteins. Here, we report that a PGRP gene, BtPGRP, encodes a PGRP from the whitefly Bemisia tabaci (MEAM1) that binds and kills bacteria in vitro. We analyzed BtPGRP transcriptional profiling, and the distribution of the cognate protein within the midgut. Fungal infection and wasp parasitization induced expressi...

The whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is a cryptic species complex that contains some of the most damaging pests in tropical and subtropical regions. Recent studies suggested that this complex is composed of at least 24 distinct species. We use the approach from these studies to consider the identity of B. tabaci in Argentina. Previous studies have suggested the prese...

Bemisia tabaci was described over 100 years ago and has since become one of the most important pests worldwide in subtropical and tropical agriculture as well as in greenhouse production systems. It adapts easily to new host plants and geographical regions and has now been reported from all global continents except Antarctica. In the last decade, international transport of plant material and pe...

Abstract The sweetpotato whitefly, Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae), is a broadly invasive pest of great economic significance to agricultural and horticultural systems in the world. contains more than 44 cryptic species, among which B. Middle East Asia Minor 1 (MEAM1) Mediterranean (MED) are most destructive, have spread many countries. Research on species increased dramatical...

A field experiment conducted during the kharif 2018 evaluated seasonal incidence of insect pests mungbean. The results revealed occurrence major sucking viz., whitefly Bemisia tabaci (Genn.), leafhopper Empoasca kerri Pruthi, aphid Aphis craccivora Koch from vegetative stage to maturity stage. lepidopterans tobacco caterpillar Spodoptera litura (F.) and blue butterfly Lampides boeticus L., were...

Whiteflies are economically important plant pests that cause damage to crops worldwide. This study aimed update the status of whiteflies in Jordan by combining classical morphological identification and DNA markers using mitochondrial cytochrome oxidase I (mtCOI) gene. Over course three consecutive years, 111 were collected from different geographical regions hosts Jordan. The results showed th...

Development of insecticide resistance in onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), populations in onion (Allium spp.) fields and the incidence of the T. tabaci transmitted Iris yellow spot virus have stimulated interest in evaluating alternative management tactics. Effects of straw mulch applied in commercial onion fields in muck areas of western New York were assessed in ...

Bacterial endosymbiosis is an important evolutionary process in insects, which can harbor both obligate and facultative symbionts. The evolution of these symbionts is driven by evolutionary convergence, and they exhibit among the tiniest genomes in prokaryotes. The large host spectrum of facultative symbionts and the high diversity of strategies they use to infect new hosts probably impact the ...

Plants under herbivore attack are able to initiate indirect defense by synthesizing and releasing complex blends of volatiles that attract natural enemies of the herbivore. However, little is known about how plants respond to infestation by multiple herbivores, particularly if these belong to different feeding guilds. Here, we report the interference by a phloem-feeding insect, the whitefly Bem...
