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

open access: yesInsects
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.

The effect of caste, mass and colony identity on rescue priorities in the red imported fire ant

open access: yesEcological Entomology, EarlyView.
Fire ants will rescue brood when the brood becomes trapped underground. We find that rescuers may use odor cues to locate trapped rescue targets. We demonstrate that a single reproductive larva is preferentially rescued over a single worker larva, but that caches of multiple worker larvae receive equal treatment as a single reproductive larva.

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

open access: yesJournal 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

Bacteriomes, cryptic forms and evolution of a common wireworm pest species, Hypnoidus bicolor

open access: yesInsect Molecular Biology, EarlyView.
Wireworms are important agricultural pests, including Hypnoidus bicolor in the Canadian Prairies. Parthenogenetic and sexual populations of H. bicolor appear associated with different molecular clades. Bacterial community composition and structure were influenced by developmental stage, sampling location and host genetics.

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

open access: yesJulius-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.

Floral Trait Influence on the Foraging Decisions of a Fly Pollinator

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Flies foraging for floral resources provide important ecosystem services through the pollination of myriad angiosperms, including many crop species. However, the specific floral cues used by fly pollinators to locate and discriminate among floral rewards and the preferences they may have for specific cues remain poorly understood.

Reproductive Capacity of Grape Root Borer, Vitacea polistiformis (Harris), and Implications for Pheromone Based Management

open access: yes, 2004
The increasing incidence of insect resistance to insecticides, and proposed governmental restrictions of pesticides on food crops have led many fruit growers to consider the use of synthetic pheromones as a method of managing lepidopteran pests ...

Attraction of bark beetles (Coleoptera : Scolytidae) to a pheromone trap - Experiment and mathematical models

open access: yes, 1984
The movement of bark beetles near an attractive pheromone source is described in terms of mathematical models of the diffusion type. To test the models, two release experiments involving 47,000 marked spruce bark beetles [Ips typographus (L.)] were ...

Preliminary laboratory and field trials of a heated pheromone trap for the sandfly lutzomyia logipalpis (Diptera: Psychodidae)

open access: yesMemorias do Instituto Oswaldo Cruz, 1990
A heated pheromone trap for the sandfly Lutzomyia longipalpis was tested in the laboratory using filter paper or plastic vial dispensers. Male pheromone extracted from 8 male tergal glands and absorbed on to filter paper dispensers attracted 82/120 (68.3%
