Climate warming promotes pesticide resistance through expanding overwintering range of a global pest

Nature Communications, 2021
Climate-driven range shifts may affect pesticide resistance. Here, the authors analyse experimentally parameterised and field-tested models to show that a cosmopolitan insect pest, the diamondback moth, is acquiring resistance against local pesticides ...

Synthesis and evaluation of novel 1-(((6-substitutedbenzo[d]thiazol-2-yl)amino)(heteroaryl)methyl)naphthalen-2-ol as pesticidal agents

Journal of Enzyme Inhibition and Medicinal Chemistry, 2022
To discover new agrochemicals with prominent pesticidal properties, a series of novel β-naphthol derivatives containing benzothiazolylamino and various heteroaryl groups (8a-q) were efficiently synthesised via Betti reaction.

Large-scale genome-wide study reveals climate adaptive variability in a cosmopolitan pest

Nature Communications, 2021
The diamondback moth is a cosmopolitan pest of significant economic importance. Here the authors analyse globally distributed genomic data to find evidence of climate-associated adaptive variation, and use an ecogenetic index to predict that it will ...

Herbivore-specific, density-dependent induction of plant volatiles: honest or "cry wolf" signals? [PDF]

PLoS ONE, 2010
Plants release volatile chemicals upon attack by herbivorous arthropods. They do so commonly in a dose-dependent manner: the more herbivores, the more volatiles released.

Biological Characteristics of Certain Diamondback Moth Ecotypes

Journal of Entomology, 2006
Studies on Diamondback moth (DBM), Plutella xylostella (L.) population gathered from eight different locations in India revealed significant variations existing among them. The tenure of life cycle of all the eight ecotypes varied from each other ranging from 20.1±1.3 to 20.9±1.01 days, longevity of adult males and females also differed.

Parasitism rate of Plutella xylostella (Lepidoptera: Plutellidae) larvae in greenhouse by Tetrastichus howardi (Hymenoptera: Eulophidae) females at different densities

Brazilian Journal of Biology, 2022
Parasitoids control insect pests, but their number per host affects their efficiency. The objective of this work was to evaluate the best density of Tetrastichus howardi (Olliff, 1893) (Hymenoptera: Eulophidae) individuals parasitizing fourth instar ...

Biological and population performance of Plutella xylostella (Lepidoptera: Plutellidae) on canola cultivars [PDF]

Journal of Crop Protection
For IPM programs, it is crucial to use plant cultivars that are less sensitive to pests or resistant to them. In this research, the susceptibility and resistance of 20 canola cultivars to the diamondback moth, one of the most destructive pests of canola ...
