Aktivitas insektisida ekstrak Piper aduncum dan Aglaia odorata terhadap Plutella xylostella (Linnaeus) (Lepidoptera: Plutellidae)

Jurnal Entomologi Indonesia
One of the main problems in the cultivation of Brassicaceae vegetable plants is the attack of diamondback moth Plutella xylostella (Linnaeus). Extracts of Piper aduncum and Aglaia odorata have the potential to be used as botanical insecticides because ...

Effects of Pyriproxyfen on Life Table Indices of Plutella xylostella in Multigenerations

Psyche: A Journal of Entomology, 2015
The diamondback moth (DBM), Plutella xylostella (L.) (Lepidoptera: Plutellidae), is a major pest of Brassicaceae family in Iran. This study investigated the sublethal effects of pyriproxyfen, a juvenile hormone analogue, on DBM, for two subsequent ...

Imported insecticide resistance in diamondback moth

New Zealand Plant Protection, 2000
Laboratory experiments were conducted to determine whether resistance in an Australian population of diamondback moth could be conferred to a local susceptible population of diamondback moth (Plutella xylostella) Bioassays with larvae showed a 715fold difference in response at the LC50 to alphacypermethrin between the resistant imported and local ...

Larval antibiosis to cabbage stem flea beetle (Psylliodes chrysocephala) is absent within oilseed rape (Brassica napus)

Pest Management Science, EarlyView.
We screened a panel of 98 Brassicaceae genotypes (97 Brassica napus and 1 Sinapis alba) for cabbage stem flea beetle (Psylliodes chrysocephala) larval antibiosis. We found limited evidence for antibiosis across B. napus but consistent antibiosis in S. alba. Brassicaceae relatives may therefore better inform resistance traits for breeding.

MAPK-dependent hormonal signaling plasticity contributes to overcoming Bacillus thuringiensis toxin action in an insect host

Nature Communications, 2020
Bacillus thuringiensis (Bt) is an important bioinsecticide, but high-level resistance has been rapidly evolving in agricultural pests. Here, Guo et al. show that the MAPK cascade can be activated by enhanced upstream insect hormone signals to counter Bt ...

Fitness costs associated with Vip3Aa resistance on various hosts in Helicoverpa zea

Pest Management Science, EarlyView.
Significant fitness costs associated with Vip3Aa resistance in H. zea were observed across three non‐Bt hosts. Abundant non‐Bt refuges could help limit the spread of Vip3Aa resistance in H. zea in the field. Abstract BACKGROUND Transgenic crops containing Bacillus thuringiensis (Bt) proteins are crucial for managing major agricultural pests such as the

Assessment of insecticides and Cry2AB toxin resistance development in Karnataka population of Plutella xylostella (Linn.) [PDF]

, 2016
Insecticidal resistance studies against third instar larvae of DBM (Plutella xylostella L.) were carried out to know the rate of development of resistance from F1 to F3 generations in Karnataka population. The third instar larvae obtained from field were

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.

Amendment to \"report of the parasitoid wasp, Diadegma anurum (Hym.: Ichneumonidae), from Iran\" [PDF]

نامه انجمن حشره‌شناسی ایران, 2013
The previous record of Diadegma anurum (Thomson) as a parasitoid of diamondback moth, Plutella xylostella (L.) (Lep.: Plutellidae), from Iran has just been a misidentification of Diadegma semiclausum (Hellen).
