Host‐associated chemical cues mediating host‐finding behaviour in the larval ectoparasitoid Cephalonomia tarsalis

Pest Management Science, EarlyView.
Host‐associated volatiles mediate host location in Cephalonomia tarsalis, with faecal odours from fourth‐instar larvae, particularly 1‐pentadecene, attracting females and supporting the biological control of stored‐product pest beetles. Abstract BACKGROUND Understanding how parasitoids locate their hosts is essential for improving the effectiveness of ...

Drought stress modulates indirect defense via bottom‐up effects in tomato and wheat

Pest Management Science, EarlyView.
Different water regimes can have a significant impact on plant morphology and defense pathways in tomato and wheat, triggering multiple olfactory choices in biocontrol agents of key insect pests. These findings could be used to implement biocontrol strategies within the IPM context under a changing climate scenario.

Evaluating predatory arthropods for the biological control of the invasive Thrips parvispinus (Thysanoptera: Thripidae) in greenhouse sweet pepper

Pest Management Science, EarlyView.
This study shows that Orius laevigatus, alone or with other predators, consistently achieved the highest suppression of Thrips parvispinus and improved plant productivity. Franklinothrips vespiformis coexisted with O. laevigatus, suggesting compatibility, while Amblyseius swirskii declined, indicating incompatibility. Individually, F. vespiformis and A.

Mapping the global threat of Mythimna separata (Walker) and its economic implications for Brazil's agriculture

Pest Management Science, EarlyView.
Global models identified high‐risk areas for Mythimna separata invasion, highlighting major economic vulnerability for Brazilian crops and guiding targeted prevention and management strategies. Abstract BACKGROUND Identifying high‐risk areas for the introduction of invasive alien species is particularly important for agricultural pests with a broad ...

Redefining generic boundaries in subtribe Eurynotina (Coleoptera: Tenebrionidae): taxonomy of the Schyzoschelus generic group

The European Zoological Journal
The genus Heteropsectropus Kaszab, 1941 (Tenebrionidae: Blaptinae: Platynotini) is revised to include the following three species: H. aenescens Kaszab, 1941 (type species); H. difficilis Koch, 1954; H. longantennatus Koch, 1954.

17‐epi‐Melianodiol, a new protolimonoid from Melia azedarach fruits, exhibits larvicidal activity and is associated with oxidative imbalance and midgut epithelial damage in Aedes aegypti larvae

Pest Management Science, EarlyView.
The bio‐guided phytochemical study resulted in the new compound 17‐epi‐melianodiol. The compound eliminated 100% of Aedes aegypti larvae at 100 ppm, causing pronounced morphological changes, cuticular damage, and extensive vacuolization. Abstract BACKGROUND In Brazil, Aedes aegypti is the primary vector of arboviruses such as dengue, chikungunya ...

Multimodal targets of (‐)‐α‐thujone mediating avoidance behavior of a stored‐products pest, Tribolium castaneum, in response to irritant stimuli

Pest Management Science, EarlyView.
We identified four kinds of target molecules against (‐)‐α‐thujone associating avoidance behavior in Tribolium castaneum, indicating multimodality. Abstract BACKGROUND The reciprocal evolutionary processes among phytophagous insects and host plants involve host shift in the herbivorous insects in response to defense chemicals, such as plant‐derived ...

Synergistic transition from type‐I‐like to type‐II‐like symptomology in a pyrethroid mixture and its impact on knockdown–mortality relationships in Musca domestica L

Pest Management Science, EarlyView.
In the present study, relationship between knockdown and mortality of insecticides was examined against the adult female housefly, Musca domestica. Type‐I pyrethroid insecticides showed a weak linkage, as early knocked down flies did not always result in mortality, while type‐II pyrethroids and organophosphates exhibited strong correlation between the ...
