Efficiency of bark beetles catch to pheromone trap in atypical conditions

A new approach to determine the capture conditions of bark beetles in pheromone-baited traps

Forests form an organic unity with a great number of organic and inorganic components and tend to maintain the sustainability of their existing balance. However, some factors which adversely affect the balance of nature may interrupt this sustainability. The epidemic which is formed by bark beetles in their spreading region, due to various factors, changes the stability so much that interferenc...

Pheromone response in pine bark beetles: influence of host volatiles.

Bark Beetles, Pityogenes bidentatus, Orienting to Aggregation Pheromone Avoid Conifer Monoterpene Odors When Flying but NotWhenWalking

Previous studies and data presented here suggest that odors from healthy host Scotch pine (Pinus sylvestris) and nonhost Norway spruce (Picea abies), as well as major monoterpenes of these trees at natural release rates, significantly reduce the attraction of flying bark beetles, Pityogenes bidentatus, of both sexes to their aggregation pheromone components grandisol and cis-verbenol in the fie...

Determinants of Farmers' Intention to Use Eco-Friendly Technologies: Pheromone Trap to Control of the Rice Pests in Simorgh County

Sustainable agriculture depends on the use of eco-friendly technologies by farmers.This research was conducted to identify and evaluate farmers' intent to use pheromone traps for controlling rice pests in paddy farms of Simorgh County, Mazandaran Province.

Relationship between Euschistus conspersus (Hem., Pentatomidae) pheromone trap catch and canopy samples in processing tomatoes

This study identified statistically significant, and practically important, seasonal pheromone trap response dynamics of Euschistus conspersus (Uhler) in processing tomatoes in 12 fields over 5 years in California, USA. Commercial fields were monitored weekly using traps baited with Euschistus spp. pheromone and direct canopy shake samples. Regression analysis determined no significant relation...
