A bacteriocyte symbiont determines whitefly sex ratio by regulating mitochondrial function

open access: yesCell Reports, 2023
Summary: Nutritional symbionts influence host reproduction, but the underlying molecular mechanisms are largely unclear. We previously found that the bacteriocyte symbiont Hamiltonella impacts the sex ratio of the whitefly Bemisia tabaci.

Lebensdauer des räuberischen Marienkäfers Serangium parcesetosum Sicard (Col., Coccinellidae) mit natürlicher und künstlicher Nahrung [PDF]

open access: yes, 2008
The little known ladybird, Serangium parcesetosum SICARD (Col., Coccinellidae) seems to be an important predator of whiteflies. It has found attacking Bemisia tabaci (GENN.) (Hom., Aleyrodidae) (KAPADIA & PURI 1992), Aleurolobus barodensis MASK (PATEL et

Side effects of pesticides used in organic and conventional tomato crops on Dolichogenidea gelechiidivoris, a parasitoid of Tuta absoluta

open access: yesPest Management Science, EarlyView.
This study reveals strong variability in the effects of eight tomato integrated pest management‐compatible pesticides on Dolichogenidea gelechiidivoris, identifying harmful compounds such as spinosad and more selective ones such as sulfur and spiromesifen, depending on the exposure route.

Assessment of soybean (Glycine max) genotypes for resistance toBemisia tabaci and its implications on yield

open access: yesThe Indian Journal of Agricultural Sciences
The whitefly, Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae), is a significant pest affecting pulse crops in north India, particularly soybean [Glycine max (L.) Merr.].

Keanekaragaman spesies kutukebul (Hemiptera: Aleyrodidae) pada tanaman hortikultura dengan ketinggian tempat berbeda di Jawa Barat

open access: yesJurnal Entomologi Indonesia, 2019
Whitefly (Hemiptera: Aleyrodidae) plays an important role as pest in many horticultural plants (fruits, vegetables, and ornamental plants). The aim of this research was to study whiteflies diversity in horticultural plants on different altitude. Whitefly

Identification of a mutation in the para-sodium channel gene of the cattle tick Rhipicephalus (Boophilus) microplus associated with resistance to synthetic pyrethroid acaricides [PDF]

open access: yes, 2009
Resistance against synthetic pyrethroid (SP) products for the control of cattle ticks in Australia was detected in the field in 1984, within a very short time of commercial introduction.

An integrative strategy used by the aphid Uroleucon formosanum to counter host sesquiterpene lactone defense: Insights from combined genomic and transcriptomic analysis

open access: yesInsect Science, EarlyView.
We report the first high‐quality chromosome‐level genome assembly for the aphid Uroleucon formosanum, a serious pest that infests lettuce in eastern Asia. A combination of comparative genomic analyses and RNA‐seq transcriptome profiling suggests that U. formosanum employs integrative mechanisms to cope with host plant‐derived sesquiterpene lactone (STL)

Interaction of Whitefly Effector G4 with Tomato Proteins Impacts Whitefly Performance

open access: yesMolecular Plant-Microbe Interactions®
The phloem-feeding insect Bemisia tabaci is an important pest, responsible for the transmission of several crop-threatening virus species. While feeding, the insect secretes a cocktail of effectors to modulate plant defense responses. Here, we present a set of proteins identified in an artificial diet on which B. tabaci was salivating. We subsequently

Differences in within‐plant oviposition preferences and immature survival between Orius predators and the importance of spatial availability of prey

open access: yesInsect Science, EarlyView.
Orius predators oviposit endophytically, and plant characteristics play an important role in their oviposition choices. In this study, we show that oviposition preferences differ between species, and that these differences may correlate with juvenile performance.

Impact of some crop management practices on tomato infestation/infection by the whitefly-begomovirus complex in Cuba [PDF]

open access: yes, 2013
Introduction. In the framework of the INCO-BETOCARIB Project titled "Begomovirus disease management for sustainable production of tomato in the Caribbean" which operated from 2003- 2006, we conducted a survey aiming at assessing the impact of cultural ...
