BACKGROUND The plant bug, Apolygus lucorum Meyer‐Dür, has begun a resurgence and has become a key pest in cotton in northern China, with the wide‐scale adoption of transgenic Bt cotton. We attempted to develop a new approach to the control of this plant bug by identifying and utilizing its sex pheromone. RESULTS Extracts from A. lucorum adults and nymphs were analyzed using gas chromatography–mass spectrometry (GC–MS) and gas chromatography–electroantennogram detection (GC–EAD) to identify the sex pheromone components. (E)‐4‐Oxo‐2‐hexenal and (E)‐2‐hexenyl butyrate were the major sex pheromone components from females and were also electrophysiology‐active towards male antennae. For males, (E)‐4‐oxo‐2‐hexenal and hexyl butyrate were the major sex pheromone components. These three components, however, were not detected in nymphs. Field tests showed that binary blends of (E)‐4‐oxo‐2‐hexenal and (E)‐2‐hexenyl butyrate at a ratio of 3:2 resulted in trapping the greatest numbers of A. lucorum males. A long‐term dispenser was developed by loading the pheromone components dissolved in sunflower oil into polyethylene vials. Further field evaluation showed that the polyethylene dispensers attracted significantly more bugs even when deployed in the field for 5 weeks. CONCLUSION We identified the sex pheromone of A. lucorum and developed a type of high‐efficiency and long‐term lure. Our results could expand knowledge of the pheromones of plant bugs, and provide novel technologies to monitor and control this pest. © 2019 Society of Chemical Industry

Transgenerational changes in pod maturation phenology and seed traits of Glycine soja infested by the bean bug Riptortus pedestris

Land plants have diverse defenses against herbivores. In some cases, plant response to insect herbivory may be chronological and even transgenerational. Feeding by various stink bugs, such as the bean bug Riptortus pedestris (Hemiptera: Alydidae), induce physiological changes in soybean, called as green stem syndrome, which are characterized by delayed senescence in stems, leaves, and pods. To investigate the plant response to the bean bug feeding in the infested generation and its offspring, we studied the effects of R. pedestris infestation on Glycine soja, the ancestral wild species of soybean. Field surveys revealed that the occurrence of the autumn R. pedestris generation coincided with G. soja pod maturation in both lowland and mountainous sites. Following infestation by R. pedestris, pod maturation was significantly delayed in G. soja. When G. soja seeds obtained from infested and non-infested plants were cultivated, the progeny of infested plants exhibited much earlier pod maturation and larger-sized seed production than that of control plants, indicating that R. pedestris feeding induced transgenerational changes. Because earlier seed maturity results in asynchrony with occurrence of R. pedestris, the transgenerational changes in plant phenology are considered to be an adaptive transgenerational and chronological defense for the plant against feeding by the stink bug.

“…Excessive use of insecticides causes development of resistance in insect targets and environmental pollution [ 3 ]. The mass use of pheromone traps could attract more insects and induce more palm infestations [ 4 ]. To minimize the problems caused by current treatments, research interest has been focused on the search for new and environmentally friendly strategies that can provide effective pest control.…”

The entomopathogenic fungus Beauveria bassiana (Bb) is used to control the red palm weevil (RPW) Rhyncophorus ferrugineus (Oliver). Beuveria bassiana can infect and kill all developmental stages of RPW. We found that a solid formulate of B. bassiana isolate 203 (Bb203; CBS 121097), obtained from naturally infected RPW adults, repels RPW females. Fungi, and entomopathogens in particular, can produce volatile organic compounds (VOCs). VOCs from Bb203 were analyzed using gas chromatography-mass spectrometry (GC-MS). GC-MS identified more than 15 VOCs in B. bassiana not present in uninoculated (control) formulate. Both ethenyl benzene and benzothiazole B. bassiana VOCs can repel RPW females. Our findings suggest that B. bassiana and its VOCs can be used for sustainable management of RPW. They could act complementarily to avoid RPW infestation in palms.

Use of aggregation pheromone traps increases infestation of adult Riptortus pedestris (Hemiptera: Alydidae) in soybean fields

Abstract: Aggregation pheromone traps did not reduce R. pedestris populations in the field or soybean damage, and even led to an increase in the bug population during autumn. Therefore, traps should not be used as a control measure. © 2018 Society of Chemical Industry.
