The diamondback moth (DBM), Plutella xylostella (Lepidoptera: Plutellidae), is a major pest of crucifers. Many volatile compounds emitted by cruciferous vegetables are known to mediate the attraction DBM adults host plant and oviposition sites. However, development highly effective attractants for management still needed. Here, we first analyzed macerated broccoli leaves with gas chromatographic-electroantennographic detection chromatography/mass spectrometry. Eight compounds, including benzaldehyde, limonene, phenylacetaldehyde, acetophenone, linalool, 2-phenylethyl alcohol, methyl salicylate, 2-methoxybenzoate, elicited robust responses from antennae. Then, conducted multiple field trapping experiments involving "addition approach" (individually adding components most abundant component, D-limonene) "subtraction evaluate attractiveness different blends. We found that 3-component blend D-limonene, 2-methoxybenzoate (3:2:1) attractant. This holds great potential monitoring P. populations.

Host plant and habitat preferences of Lygus bugs: consequences for trap cropping applications

Arthropod-Plant Interactions, Journal Year: 2024, Volume and Issue: 18(6), P. 1161 - 1188

Abstract Lygus bugs (Hemiptera: Miridae) can damage economically important crop plants by feeding on their active growing points, such as the apical meristem and buds, reproductive organs, flower flowers, seeds, fruits. Plant injury is a combination of mechanical stylet effects saliva, which contains enzymes that break plant cells. On some occasions, oligophagous species act biocontrol organisms when predating eggs larvae pest insects. This review summarises studies where trap crops have been used to control bug populations various reduce crops. We also focus factors affect host habitat selection highly polyphagous discuss reasons why less favourable in laboratory might become attacked field. An analysis rapidly developed worldwide problems conifer nurseries late 1970s early 1980s presented an example how adapt changes environmental conditions new types suggest rate irrigation efficiency weed could be augmenting severity damage. These should considered planning strategies for spp.
