Tradeoff between triglyceride consumption and ovariole development in Plutella xylostella (L.) released in mixed-host environments

Journal of Integrative Agriculture, 2019
After exposure to mixed environments with multiple hosts, the frequency of flight take-offs for Plutella xylostella (L.) is known to increase with a concomitant decrease in female fecundity.

Synthetic biology approaches to generate temperature‐sensitive alleles for the Sterile Insect Technique

Insect Science, EarlyView.
Abstract The Sterile Insect Technique (SIT) is an environmentally friendly, sustainable pest control approach, which uses large‐scale releases of sterile insects to suppress or eradicate target populations through infertile matings. The efficiency of SIT is enhanced by male‐only releases requiring genetic sexing strains (GSSs) that are classically ...

Effects of host plant on the oviposition preference of Plutella xylostella (L.) and host- selection behavior of Cotesia plutellae (Kurdjmov)

浙江大学学报. 农业与生命科学版, 2001
The ovipositional preference of the diamondback moth, Plutella xylostella (L.) between different Brassica vegetable plants and the host selection by Cotesia plutellae (Kurdjmov) between host larvae on different Brassica plants were studied.

Neoclassical development of genetic sexing strains for insect pest and disease vector control

Insect Science, EarlyView.
The sterile insect technique has been effectively used for decades, and an important component is the availability of sex separation systems, in particular genetic sexing strains. Classical approaches, such as irradiation‐induced chromosomal translocations, have yielded stable strains for species like the Mediterranean fruit fly.

Herbivore range expansion triggers adaptation in a subsequently-associated third trophic level species and shared microbial symbionts

Scientific Reports, 2019
Invasive species may change the life history strategies, distribution, genetic configuration and trophic interactions of native species. The diamondback moth, Plutella xylostella L., is an invasive herbivore attacking cultivated and wild brassica plants ...

Molecular Phylogeny and Strain Genotyping of the Bacterial Endosymbiont Wolbachia Associated With Tuta absoluta Populations

Entomologia Experimentalis et Applicata, EarlyView.
This study was designed to understand the association between reproductive endosymbiotic bacteria and wild and laboratory‐reared Tuta absoluta populations. The majority of T. absoluta populations showed Wolbachia presence at varying levels of infection, whereas Arsenophonus, Cardinium, and Spiroplasma were not detected. Wolbachia‐positive T.

Tactics of applying entomopathogenic fungi in the control of Plutella xylostella and Brevicoryne brassicae [PDF]

Brazilian Journal of Biology
Plutella xylostella L., 1758 (Lepidoptera: Plutellidae) and Brevicoryne brassicae L., 1758 (Hemiptera: Aphididae) are important pests of Brassicaceae, causing significant damage that makes human consumption of these vegetables impossible.

Cost of parasite exposure depends on host ontogeny 寄生接觸的代價依賴於宿主發育階段

Ecological Entomology, EarlyView.
The cost of parasite exposure varies across host developmental stages, demonstrating that ontogeny influences the expression of non‐consumptive effects (NCEs). Mite exposure resulted in consumptive effects in fly eggs and NCEs in early‐stage pupae; mite longevity was comparable when provisioned with pupae or water but increased when provisioned with ...
