Harmonia axyridis: a threat to Brazilian Coccinellidae?
Harmonia axyridis (Pallas) (Coleoptera, Coccinellidae) is a polyphagous Asian species, well-known as a classical biological control agent of aphids around the world, introduced probably accidentallyExpand
Volatile Organic Compounds of Conspecific-Damaged Eucalyptus benthamii Influence Responses of Mated Females of Thaumastocoris peregrinus
Plants respond to herbivory by synthesizing and releasing novel blends of volatile organic compounds (VOCs). Natural enemies are attracted to these VOCs, but little is known about the effects ofExpand
Volatile Chemicals of Adults and Nymphs of the Eucalyptus Pest, Thaumastocoris peregrinus (Heteroptera: Thaumastocoridae)
Thaumastocoris peregrinus is an introduced “true bug” that is now a severe pest in Eucalyptus plantations of various Southern Hemisphere countries. The semiochemicals of thaumastocorids areExpand
Longer decomposition process and the influence on Coleoptera fauna associated with carcasses.
Cadavers are colonized by different species of animals, mainly insects such as flies and beetles (Kocarek, 2003). The succession of these insects and the time they live on the carcasses is used toExpand
Identificaton of the Alarm and Sex Pheromones of the Leaf-Footed Bug, Leptoglossus zonatus (Heteroptera: Coreidae)
The leaf-footed bug, Leptoglossus zonatus (Heteroptera: Coreidae), is mainly found in maize fields in Brazil. In this work, we elucidated and quantified the volatile compounds from nymphs and adultsExpand
Compostos orgânicos voláteis na defesa induzida das plantas contra insetos herbívoros
The identification and manipulation of chemical compounds involved in vital activities of arthropods have the potential for developing less aggressive pest control strategies. Herbivory induces theExpand
Cuticular Compounds Recognition and Mating Behavior of the Rice Water Weevil Oryzophagus oryzae (Coleoptera, Curculionidae)
Oryzophagus oryzae mating behavior and mate recognition were investigated. Bioassays revealed that couples had intense sexual activity in the first 3 h of photophase and scotophase. Adults mated andExpand
The Male Produced Aggregation Pheromone of a Strawberry Sap Beetle, Lobiopa insularis (Coleoptera: Nitidulidae)
The nitidulid beetle Lobiopa insularis is an important pest of strawberry crops in the United States and Brazil. Both larvae and adults feed on ripe strawberries, causing 20–70% loss in productionExpand
Scanning electron micrographs of Oryzophagus oryzae (Coleoptera, Curculionidae), plastron structure and swimming behavior.
The morphological structures that permit Oryzophagus oryzae aquatic activities and swimming behavior were studied and compared with various weevils and other relevant species. The use of scanningExpand
Evidence for Sex-Specific Pheromones in Ulomoides dermestoides (Coleoptera, Tenebrionidae)
Ulomoides dermestoides (Fairmaire, 1893) is an Asiatic insect used for medicinal purposes all over the world. In Brazil, people buy these insects in animal product stores not only to feed birds andExpand
