Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

open access: yesPest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

Colonisation potential of the bark beetle (Taphrorychus bicolor) on beech logs and logging residues: ecological context and implications for pest management in forests

open access: yesPest Management Science, EarlyView.
Beech residues left in shaded or semi‐shaded conditions pose a substantial risk of local Taphrorychus bicolor population outbreaks. The rapid removal or placement of residues in sun‐exposed locations can help mitigate this risk. Abstract BACKGROUND The bark beetle Taphrorychus bicolor has been traditionally classified as a secondary pest of European ...

Treatment of cotton with plant growth‐promoting rhizobacteria consortium alters host location and oviposition of Spodoptera exigua

open access: yesPest Management Science, EarlyView.
Two plant‐growth promoting rhizobacteria (PGPR) consortia (AU8 and TX1) induced a deterrence of host plant location and oviposition behavior of Spodoptera exigua females in both susceptible and resistant cotton plants. Most of the volatile organic compounds (VOCs) increased in PGPR‐treated plants compared to untreated plants. # indicates treatments not

Host‐associated chemical cues mediating host‐finding behaviour in the larval ectoparasitoid Cephalonomia tarsalis

open access: yesPest Management Science, EarlyView.
Host‐associated volatiles mediate host location in Cephalonomia tarsalis, with faecal odours from fourth‐instar larvae, particularly 1‐pentadecene, attracting females and supporting the biological control of stored‐product pest beetles. Abstract BACKGROUND Understanding how parasitoids locate their hosts is essential for improving the effectiveness of ...

Attraction of Phoracantha mastersi (Coloeptera: Cerambycidae) to copulation‐associated olfactory stimuli

open access: yesAgricultural and Forest Entomology, EarlyView.
Damage caused by Phoracantha mastersi larvae are the primary cause of forest decline in Australia's subalpine forests. Behaviour of male adult beetles was tested in response to a suite of commercial semiochemicals and conspecifics engaged in active copulation within a Y‐maze.

Refuge by day, forage by night: Diel activity of vine weevil as characterised by smart monitoring

open access: yesAgricultural and Forest Entomology, EarlyView.
Vine weevil activity was monitored using a Smart trap, which recorded diel refuge‐seeking behaviour. Increasing light intensity triggered refuge seeking behaviour, while lower light intensity induced forage seeking activity. Understanding vine weevil diel activity can enhance early detection, which can improve the effectiveness of integrated pest ...

Evaluation of host-derived volatiles for trapping Culicoides biting midges (Diptera: Ceratopogonidae) [PDF]

open access: yes, 2017
Culicoides biting midges (Diptera: Ceratopognidae) cause pain and distress through blood feeding, and transmit viruses that threaten both animal and human health worldwide.

Bignoniaceae Metabolites as Semiochemicals

open access: yesMolecules, 2010
Members of the family Bignoniaceae are mostly found in tropical and neo-tropical regions in America, Asia and Africa, although some of them are cultivated in other regions as ornamentals.

Chemical Cues for Malaria Vectors Oviposition Site Selection:\ud Challenges and Opportunities [PDF]

open access: yes, 2013
The attractiveness of oviposition site for malaria vector mosquitoes is dependent upon a number of physical and chemical factors. Many aspects of mosquito behavior, including host location and oviposition, are mediated by volatile semiochemicals.
