Effect of Berenuk Fruit Extract (Crescentia cujete L.) on Mortality of Plutella xylostella on Mustard Plants

Quagga
Mustard production in Indonesia in 2022 decreased by 2.9% from the previous year, caused by the Plutella xylostella attack. Efforts to control P. xylostella usually uses synthetic pesticides but harms the environment, so other alternatives are needed ...

A single transcription factor facilitates an insect host combating Bacillus thuringiensis infection while maintaining fitness

Nature Communications, 2022
Plutella xylostella endures Bt toxins with no performance costs. This study reveals how, depending on the presence of the toxin, this insect modifies MAPK phosphorylation to modulate the transcription factor FTZ-F1 binding, to up- or down- regulate Bt ...

High‐throughput transcriptome mining and in silico screening reveal saccharide feeding stimulants for Cydia pomonella larvae

New Plant Protection, EarlyView.
We identified and characterized the gustatory and ionotropic receptors of Cydia pomonella using transcriptomics and in silico approaches, linking candidate sugar receptors to larval feeding attraction. Functional assays and behavioral tests highlighted isoquercitrin as a key feeding stimulant, providing a foundation for olfactory‐ and taste‐based pest ...

Intraspecific and Interstage Similarities in Host-Plant Preference in the Diamondback Moth (Lepidoptera: Plutellidae)

Horticulturae, 2022
The diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidae), is an important insect pest of cruciferous crops. Understanding its preference patterns can lead to more efficient management methods, such as trap crops.

SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

Pest Management Science, EarlyView.
SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

Synthesis and Bioactivities of Novel Pyrazole Oxime Derivatives Containing a 5-Trifluoromethylpyridyl Moiety

Molecules, 2016
In this study, in order to find novel biologically active pyrazole oxime compounds, a series of pyrazole oxime derivatives containing a 5-trifluoromethylpyridyl moiety were synthesized. Preliminary bioassays indicated that most title compounds were found

Variation among 532 genomes unveils the origin and evolutionary history of a global insect herbivore

Nature Communications, 2020
The diamondback moth, Plutella xylostella is a cosmopolitan agricultural pest. By analyzing 532 genomes from 114 populations around the world, the authors find evidence supporting a South American origin of this moth, and look for signatures of positive ...

Odorant Receptor PxylOR11 Mediates Repellency of Plutella xylostella to Aromatic Volatiles

Frontiers in Physiology, 2022
Insects can use plant volatiles to guide certain behaviors, such as courtship, mating, host positioning, and habitat selection. Plutella xylostella is a global agricultural pest and has always been closely studied, but relatively few studies assess the ...

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.
