Testing and improving the effectiveness of trap crops for management of the diamondback moth Plutella xylostella (L.): a laboratory-based study [PDF]

open access: yes, 2009
BACKGROUND: The aim of this study was to assess white mustard (Sinapis alba L.) as a trap crop for diamondback moth [Plutella xylostella (L.)] on cauliflower [Brassica oleracea (L.) var. Lateman].

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

open access: yesNature 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

open access: yesJournal 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.

Assessing risks and benefits of floral supplements in conservation biological control [PDF]

open access: yes, 2010
The use of flowering field margins is often proposed as a method to support biological control in agro-ecosystems. In addition to beneficial insects, many herbivores depend on floral food as well.

Lack of correlation between constitutive and induced resistance to a herbivore in crucifer plants: real or flawed by experimental methods? [PDF]

open access: yes, 2009
The correlation between constitutive and induced resistance to herbivores in plants has long been of interest to evolutionary biologists, and various approaches to determining levels of resistance have been used in this field of research.

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

open access: yesPLoS 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.

Selenium-Tolerant Diamondback Moth Disarms Hyperaccumulator Plant Defense [PDF]

open access: yesCurrent Biology, 2006
Some plants hyperaccumulate the toxic element selenium (Se) to extreme levels, up to 1% of dry weight. The function of this intriguing phenomenon is obscure.Here, we show that the Se in the hyperaccumulator prince's plume (Stanleya pinnata) protects it from caterpillar herbivory because of deterrence and toxicity.

Simultaneous Parasitism of Field-Collected Green Cloverworm, \u3ci\u3eHypena Scabra\u3c/i\u3e (Lepidoptera: Noctuidae) Larvae by Endoparasitioids and an Entomopathogenic Fungus [PDF]

open access: yes, 2018
The impacts of entomopathogens (e.g., fungi, bacteria, protists and viruses) on larval Lepidoptera and their associated insect parasitoids have been examined in laboratory studies but field studies of interaction between these two mortality factors are ...

Pesticide resistance in Plutella xylostella (Lepidoptera: Plutellidae) populations from Togo and Benin [PDF]

open access: yes, 2016
Published online: 17 August 2016The diamondback moth, Plutella xylostella (L.) is the major insect pest of cabbage crops in Togo and Benin. For control, farmers very often resort to spraying chemical insecticides at high dosages with frequent ...

Effects of extracts from Tiam seeds on diamondback moth (Plutella xylostella Linn.) [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2004
n-Hexane and methanolic extracts from the seeds of Azadirachta excelsa Jack. (Tiam) and A. indica var. siamensis Valeton, Bacillus thuringiensis var. kurstaki HD-1 and abamectin were tested for mortality effect on the 2nd and the 3rd instar larvae of ...
