Abstract After herbivore attack or chemical activation, plants release a blend of volatile organic compounds (VOCs) that is qualitatively quantitatively different to the emitted by an undamaged plant. The altered VOCs then usually attractive herbivore's natural enemies. Soybean, Glycine max (L.) (Fabaceae), when damaged stink bug herbivory, has been shown emit attracts egg parasitoid Telenomus podisi (Ashmead) (Hymenoptera: Scelionidae) In this study, our aim was investigate changes in VOC...
Abstract Herbivory is known to increase the emission of volatiles, which attract natural enemies herbivore‐damaged plants in laboratory and agricultural systems. We report on signalling through volatiles induced by Euschistus heros (F.) (Heteroptera: Pentatomidae) two legumes that influence attraction retention egg parasitoid Telenomus podisi (Ashmead) (Hymenoptera: Scelionidae). Air‐borne extracts obtained from host E. , soybean, Glycine max pigeon pea, Cajanus cajan (Leguminosae), produce...
Abstract. The stink bugs Acrosternum impicticorne , Euschistus heros Piezodorus guildinii and Thyanta perditor (Heteroptera: Pentatomidae) feed mate on the same host plants constitute major components of soybean pest complex in Brazil. During mating, they communicate with species sex‐specific vibratory signals whose spectral properties are characteristic subfamily Pentatominae. Songs differ between time structure amplitude modulation their units. repertoire A. E. T. fits into scheme...
The objective of this work was to improve the mass rearing technique Euschistus heros in laboratory. Nymphs and adults were reared at densities 100, 200, 300 400 eggs per Petri dish (9 cm diameter), 50, 150 200 couples cages (900 mL), respectively. Survival rate immature stages survivorship reproduction determinated. Survivorship nymph adult highest (89%) density 100 dish. Adult independent density, cage best quality produced progeny. In these conditions, fecundity 160.8±9.28 female, a total...
Abstract The effectiveness of the synthetic sex pheromone Neotropical brown stink bug, Euschistus heros , was evaluated both in laboratory and field assays. Lures loaded with 1 mg methyl 2,6,10‐trimethyltridecanoate (TMTD) continuously attracted female bugs for more than 30 days to pheromone‐baited traps trials. were effective tests even at low bug population densities, as compared usual monitoring technique, shake cloth sampling. Traps around borders or centre soybean fields caught similar...
Diaphorina citri is a vector of the bacterial causative agent Huanglongbing (HLB = Citrus greening), severe disease affecting citrus crops. As there no known control for HLB, manipulating insect behaviour through deployment semiochemicals offers promising opportunity protecting The behavioural responses D. to plant volatiles, and identity these volatiles were investigated. Volatiles collected from host plants Murraya paniculata, sinensis, C. reshni, limettioides, Poncirus trifoliata,...
Introdução: a Doença de Alzheimer (DA) é uma condição neurodegenerativa multifatorial que representa principal causa demência no mundo. Evidências sugerem fatores comportamentais, como dieta, atividade física, qualidade do sono e manejo estresse, desempenham papéis significativos na prevenção progressão da DA. A compreensão desses essencial para o desenvolvimento intervenções eficazes. Metodologia: foram incluídos estudos publicados entre 2013 2023, disponíveis em português inglês,...
The banana weevil (Cosmopolites sordidus) is a significant pest that reduces yields and can result in plant mortality. (2R,5S)-theaspirane, kairomone from senesced leaves, one of the natural volatiles, aiding attraction. A rapid cost-effective synthesis (2R,5S)-theaspirane was developed utilizing microwave-assisted conditions principles green chemistry. process comprised five steps, beginning with reduction dihydro-β-ionone, followed by lipase-mediated kinetic resolution to attain high...
Abstract. The semiochemical cues used by geographically isolated strains of the parasitoid, Telenomus podisi (Ashmed), to find eggs stink bug Euschistus heros were investigated. Two Te. , maintained on a South American host ( E. ) studied. One parasitoid strain originated from specimens collected near Brasilia, Brazil (SA strain), and second at Beltsville, Maryland (NA strain). Cold tolerance tests adults NA SA strains, analyses cuticular hydrocarbons between two crossing experiments each...
Egg parasitoids have a short time frame in which their host eggs are suitable for parasitism, and several systems these respond to plant volatiles induced by oviposition on the (either isolation or combination with feeding damage) as means of finding hosts. It is known that parasitoid pentatomid Telenomus podisi responds damage done soybeans female Euschistus heros, its preferred host. In this study our aim was determine type E. heros soybean (herbivory, both) necessary attraction T. podisi....
