Root knot nematodes (RKNs) cause significant crop losses. Although RKNs and entomopathogenic fungi, such as Metarhizium brunneum, are associated with plant roots, very little is known about the interactions between these two organisms. This study showed that conidia VOCs of Me. brunneum influenced behaviour M. hapla. The response was dependent on fungal strain, VOC, concentration both VOC conidia, time. Tomatoes planted in soil treated highest doses usually had a higher number than untreated...

Slugs and snails constitute major crop pests. Withdrawal of metaldehyde has prompted a search for more environmentally friendly yet fast acting molluscicides. This study investigated the response representative molluscs to conidia volatile organic compounds (VOCs) insect pathogenic fungus Metarhizium brunneum Petch.Conidia M. had antifeedant/repellent properties with repellency being dependent upon fungal strain concentration. Three commonly produced VOCs, 1-octene, 3-octanone 1-octen-3-ol,...

Microbes associated with the external and internal anatomy of three commercially available predatory mite species—Phytoseiulus persimilis, Typhlodromips (= Amblyseius) swirskii, Neoseiulus cucumeris—were examined using light microscopy, confocal laser scanning microscopy fluorescence in-situ hybridization (FISH). Four microbe morphotypes were observed on body regions. These included microfungi-like organisms (named T1, T2 T3) rod-shaped bacteria (T4). Morphotypes showed unique distributions...

New pest management solutions are needed to control soil invertebrates (insects, nematodes, mollusks) in order implement the goals of European Green Deal. Natural volatile organic compounds (VOCs) such as 1-octen-3-ol and 3-octanone, emitted by entomopathogenic fungus Metarhizium brunneum could be part solution. Three major crop pests, Agriotes lineatus (wireworm), Diabrotica virgifera (corn rootworm) Phyllopertha horticola (garden chafer), were susceptible fumigation with 3-octanone. The...

Abstract: In laboratory trials, mating behaviour of males Lobesia botrana Den. and Schiff. (Lep., Tortricidae) was investigated after treatment with an electrostatically chargeable powder, Entostat TM . Male moths were powdered either blank or containing sex pheromone. Significantly more adhered to L. when pheromone added the powder compared Entostat. Powdering male Entostat, without pheromone, caused a significant reduction in antennal response antennae placed 2 cm away downwind direction,...

The whitefly and thrips predator Typhlodromips swirskii (Athias-Henriot) (Acari: Phytoseiidae) can be reared on the factitious astigmatid mite Suidasia medanensis (Oudemans) Suidasiidae). predator–prey relationship allows system to incorporated into a breeding sachet which releases predators crop over several weeks ensuring presence arrival of target pests increased numerical response through immigration from sachet. This study investigated whether prey preference functional T. different...

Abstract: Entostat TM is an electrostatically charged wax powder that used as a carrier particle in novel delivery systems for contaminating target insect pests with insecticides, biologicals or pheromones. Here, the adhesion of two forms to Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann) was examined, and live dead medflies compared. From controlled contaminations medflies, it shown acquired larger quantities than which could be due electrostatic charge carried by insects....

Powders that adhere to insect cuticle can be used as carrier particles for synthetic insecticides, entomopathogens, or pheromones in control systems, and insects lured into contact with such powder mixtures by using attractants. Secondary transfer of adhesive powders conspecifics during social interactions has been reported; however, this relies on leaving the source continuing normal behavior when contaminated. We examined ability Mediterranean fruit fly, Ceratitis capitata Wiedemann...

Abstract The volatile organic compounds (VOCs) 1-octen-3-ol and 3-octanone produced by the entomopathogenic fungus Metarhizium brunneum are known to have pesticidal properties at high doses against a range of invertebrate pests. Very little is about their behavior-modifying (semiochemical) properties. This study focused on investigating behavioral responses three subterranean crop pests, wireworm ( Agriotes lineatus ) , western corn rootworm Diabrotica virgifera ), garden chafer Phyllopertha...

Phytoseiidae predatory mites are used as biological control agents in glasshouse environments to pestiferous and insects. The influence of the microbiomes on these within mass-reared facilities is largely unknown; this study aims improve our understanding microbiome. We Sanger sequencing traditional culturing methods characterise dominant species external internal bacterial microbiotas three commercially reared mites: Phytoseiulus persimilis , Typhlodromips (=Amblyseius) swirskii Neoseiulus...

Abstract Numerous semiochemicals have been isolated from several species of astigmatid mites with various identified or unidentified functions. Alarm pheromonal activity is widespread neryl formate and neral, being the most common compounds eliciting alarm response in conspecifics. The cosmopolitan mite S uidasia medanensis (= . pontifica ) O udemans ( A cari: uidasidae) has reported to use neral as an pheromone, but can also act allomone towards predators oribatid mites. be utilised a...

As the United Kingdom attempts to uncover benefits from Brexit, regulatory reform for various industries has become a critical topic of discussion. One area that demands careful consideration is regulation pesticides and, in particular, biopesticides. These crop protection products, which may be microorganisms (or constituents thereof), or derivatives natural materials like plants and certain minerals (the precise definition ‘biopesticide’ varies considerably depending upon whom you’re...
