Ozone‐driven degradation of sex pheromone in Plutella xylostella: Implications for reproductive communication and mating success

Insect Science, EarlyView.
In this study, we examined whether realistic ozone concentrations can interfere with sexual communication in the insect pest Plutella xylostella, the diamondback moth. Ozone exposure caused a degradation of pheromone components, leading to significant changes in blend composition and component ratios.

Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived bacterial semiochemicals

Insect Science, EarlyView.
Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived airborne semiochemicals. Egg‐borne bacterial symbionts, and Serratia marcescens in particular, produce odorants which attract gravid female flies and elicit oviposition.

Different combinations of pheromone trap, dispenser and chemical treatments for controlling the mango fruit fly, Bactrocera zonata Saunders (Diptera: Tephritidae) [PDF]

Journal of Advances in Plant Protection
Using pheromone traps is one of the standard methods to control the mango fruit fly, Bactrocera zonata (Saunders) (Diptera: Tephritidae). The lower efficiency of traps has made it inevitable to consider more efficient methods of controlling this pest ...

From glacial echoes to timber pathways: Climatic–historical drivers and timber‐trade influence on the phylogeography of Ips sexdentatus in the Basque Country

Agricultural and Forest Entomology, EarlyView.
Ips sexdentatus is expanding across southern Europe, attacking multiple Pinus species and showing the ability to colonize trees at early stages of decline. Genetic analysis of 668 individuals revealed 106 haplotypes, with Iberian populations as diversity hotspots, reflecting long‐term refugial persistence alongside more recent demographic expansion ...

Physiological Status of Rice Leaf-Roller Cnaphalocrocis medinalis (Lepidoptera: Crambidae) Adults Trapped by Sex Pheromone and Floral Odor

Insects
The rice leaf-roller Cnaphalocrocis medinalis is an important migratory pest of rice. We conducted a study to determine the physiological status of adults trapped by a sex pheromone and floral odor.

Using a Generic Blend of Pheromones to Simultaneously Attract a Diversity of Elaterid Beetle Species Native to Eastern North America

Entomologia Experimentalis et Applicata, EarlyView.
We assessed attraction of eight elaterid species to a “generic” pheromone blend containing their eight known pheromones or sex attractants. All eight species were attracted by their specific attractants, as expected. Six species were attracted to the blend, but the remaining two species were strongly inhibited by unknown blend components.

The sex ratio of spruce bark beetles - Ips typographus (Coleoptera: Curculionidae: Scolytinae) captured in different types of traps

Journal of Forest Science
In forest protection, various types of trap systems are used against spruce bark beetles to treat the foci of infested areas. Traditionally, these include pheromone traps, treated trap trees, and recently also the application of Storanet insecticide nets

The orientation of Tribolium castaneum adults in the presence of aggregation pheromone 4,8-Dimethyldecanal and food oils

Julius-Kühn-Archiv, 2018
Monitoring of Tribolium castaneum, the red flour beetle, involves the use of aggregation pheromone 4,8- dimethyldecanal (4,8 DMD) and kairomones such as cereal oils.

Landscape and Geography Determine Saproxylic Beetle Captures in Pheromone‐Baited Traps

Entomologia Experimentalis et Applicata, EarlyView.
Pheromone‐baited traps at 39 forest sites across southern Sweden captured 58 saproxylic beetle species, including seven Red‐listed taxa. The effect of surrounding forest cover on beetle abundance may depend on latitude and longitude: positive effects were strongest in warmer southern and eastern regions but weakened or reversed in colder northwestern ...
