Direct parental CRISPR gene editing in the predatory bug Orius strigicollis, a biocontrol agent against small arthropods.

Background: The predatory flower bug Orius strigicollis serves as a valuable biocontrol agent against small arthropods; however, its effectiveness can vary, especially when population establishment fails due to low prey/pest densities. A promising approach to improve the efficacy of O. strigicollis as a biocontrol agent is through gene editing.

A new pest suction machine to control Bemisia tabaci (Hemiptera: Aleyrodidae) in tomato greenhouses.

The sweetpotato whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is challenging to control using chemical pesticides owing to its resistance to many insecticides. Thus, there has been an increasing demand for alternative control measures. Thus, this study evaluated the efficacy of a newly designed pest suction machine to manage whiteflies on tomato plants (Solanum lycopersicum L.

Origin, selection, and spread of diamide insecticide resistance allele in field populations of diamondback moth in east and southeast Asia.

Background: The investigation of molecular mechanisms and evolution of resistance to insecticides is an ongoing challenge, as researchers must provide guidance to manage the resistance to achieve sustainable production in agriculture. Predicting, monitoring, and managing insecticide resistance requires information on the origins, selection, and spread of resistance genes. The resistance of Plutella xylostella (L.

An Efficient Method for Monitoring Predatory Minute Pirate Bugs Orius spp. (Hemiptera: Anthocoridae) Populations Using Blue-Colored Sticky Traps.

Minute pirate bugs of genus Orius (Wolff) are known important generalist predators of microinvertebrate pests and are therefore useful in many agricultural contexts. Effective sampling methods are thus of great importance to monitor Orius spp. populations.

Mass fingerprint analysis of spider mites (Acari) by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry for rapid discrimination.

Rationale: Discrimination of spider mite species is still performed using morphological information, although DNA and other biological approaches have been attempted for identification purposes. These techniques need much time, are expensive, and require specialist staff. As an alternative, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) analysis is applied for rapid discrimination of spider mite species.
