AbstractCerambycid species of the Spondylidinae subfamily are distributed worldwide and are known for being prolific invaders that infest conifers. In New Zealand, Arhopalus ferus (Mulsant), the burnt pine longhorn beetle, is well-established and requires monitoring at high-risk sites such as ports, airports, and sawmills as part of the requirements to

Integrated Management of Major Coconut Pests Using Pheromone Lures
Red palm weevil Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae; Rhinoceros beetle Oryctes rhinoceros Linn. (Coleoptera: Scarabidae) and Black headed caterpillar Opisina arenosella Walker (Lepidoptera: Oecophoridae) are the three among major

Emission of alarm pheromone by non-preyed aphid colonies [PDF]
peer reviewedThe sesquiterpene (E)-beta-farnesene (E beta f) is the primary component of the alarm pheromone of most aphid species. It is released in response to physical stress including attack by natural enemies and causes aphids to cease feeding and ...

While foraging, animals can form inter- and intraspecific social signalling networks to avoid similar predators. We report here that foragers of different native Asian honey bee species can detect and use a specialized alarm pheromone component, benzyl ...

Human pheromones and food odors: epigenetic influences on the socioaffective nature of evolved behaviors [PDF]
Olfactory cues directly link the environment to gene expression. Two types of olfactory cues, food odors and social odors, alter genetically predisposed hormone-mediated activity in the mammalian brain.The honeybee is a model organism for understanding the epigenetic link from food odors and social odors to neural networks of the mammalian brain, which

9-Methylgermacrene-B is confirmed as the sex pheromone of the sandfly Lutzomyia longipalpis from Lapinha, Brazil, and the absolute stereochemistry defined as S [PDF]
The structure of the sex pheromone produced by the male sandfly Lutzomyia longipalpis, from the Lapinha Cave (Minas Gerais State) region of Brazil, previously proposed tentatively as the novel homosesquiterpene 9- methylgermacrene-B, is confirmed and the

Physical and biological effects on moths’ navigation performance
In a chemosensing system, the local olfactory environment experienced by a foraging organism is defined as an odorscape. Using the nocturnal pink bollworm moth (Pectinophora gossypiella), we tested the combined effect of three biophysical aspects in its ...

Background In Africa, food legumes such as cowpeas and beans constitute important sources of proteins for millions of rural and urban populations. However, attacks by multiple pest species can reduce yields by up to 80%.

Dead wood retention and the risk of bark beetle attack [PDF]
Wind-felled Norway spruce trees left for conservation purposes and spruce stems stored as forest fuel may be colonised by the bark beetles Ips typographus and Pityogenes chalcographus (Coleoptera: Scolytidae).
