Plants are frequently exposed to heat stress as a result of global warming. Heat leads series physiological responses including volatile elicitation, but how stress-induced cues affect the behavior herbivores is poorly understood. In this study, polyphagous herbivore Spodoptera litura (tobacco cutworm, TCW) and Chrysanthemum nankingense were selected model elucidate interactions between plant c...

Fall armyworm, Spodoptera frugiperda , is a serious invasive pest in Africa but “Push-Pull” companion cropping can substantially reduce infestation. Here, we elucidate the underpinning chemical ecology mechanisms. We hypothesized that crop volatiles repel herbivores (push) while attracting natural enemies (pull). Headspace collected from plants ( Desmodium intortum, uncinatum Brachiaria Mulato ...

environmental friendly pesticides with a natural origin can be used as an alternative to chemicals in plant pests control programs. from this perspective, the extract of ginkgo biloba l. plant is important. in this study which was conducted in 2010, the ethereal extract of exocarp and kernel of g. biloba seed was analyzed using a gas chromatograph mass spectroscope. the components included gink...

Abstract Generalist predators are increasingly used in biological pest control for greenhouse crops, as they multiple pests and persist crops even when prey is scarce. However, some of these may cause plant damage due to their omnivorous feeding behaviour. In many European regions, the predator Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae) considered be a serious tomato pest, regardless ser...

Introduction Tuta absoluta is currently considered one of the most devastating invasive pests solanaceous plants worldwide, causing severe damage to tomato industry. Insects use volatile organic compounds (VOCs) locate host plant for feeding and oviposition. Those VOCs could be developed as lures pest monitoring control. Methods In this study, differentially accumulated between preferred (tomat...

The spotted lanternfly (SLF), Lycorma delicatula (Hemiptera: Fulgoridae), is a generalist phloem feeder that produces copious amounts of honeydew, which in turn coats the understory. These insects form large aggregations covering trunks some trees, while similar trees nearby mysteriously seem unattractive. We investigated whether volatiles from SLF honeydew are attractive to conspecifics by col...

BACKGROUND Biological control plays a key role in reducing crop damage by Tuta absoluta (Meyrick) and Trialeurodes vaporariorum (Westwood), which cause huge yield losses tomato (Solanum lycopersicum L.). The mirid predator Nesidiocoris tenuis (Reuter) preys heavily on these pests, with satisfying levels greenhouses. Although N. is known to be attracted volatiles of plants infested T. whitefly, ...
