Damage appraisal and pheromone trapping studies for the black army cutworm in British Columbia. Author(s): Maher, T. Author Affiliation: TFM Forestry Ltd., Author: T. Maher. Damage: The most important cutworm in B.C.'s forests is the black army cutworm Actebia fennica.

The larvae are defoliators, feeding in the daylight hours in the spring, but as the season warms they hide in the soil by day and feed only after sunset. Monitoring the Black Cutworm with Pheromone Traps.

The black cutworm monitoring and forecasting program is coordinated by the MU-IPM Program, in cooperation with the MU Commercial Agriculture Program's climatologists and programmers with the MU AgEBB (Agriculture Electronic Bulletin Board).The MU IPM program supports volunteer trappers in approximately 25 Missouri counties ().

This is a mature black cutworm. Note the dark, greasy appearance and the pebbly texture of the skin. Remember that other cutworm species may be present in the field, such as dingy, darksided, or claybacked cutworms.

A prototype ground-based pheromone trap design, baited with various pheromone lures, was field tested for effectiveness in trapping male Agriotes obscurus and Agriotes lineatus click beetles in British Columbia.

Pheromone dispensers containing geranyl octanoate and geranyl hexanoate in a ratio caught the greatest numbers of A. obscurus, whereas those containing geranyl octanoate and Cited by: In fields where stands are thin and poorly tillered, 1 or 2 army cutworms per square foot may justify treatment.

With vigorous wheat stands, treatment is usually not necessary until populations average 4 to 5 worms per square foot. It is important to detect and control army cutworms while they are small, before they cause significant crop losses.

Storm systems from the Southwestern portions of the country have brought more than rain showers. Many of our pheromone trap cooperators captured black cutworm moths over the last week though numbers are relatively low.

Most surprising was the number of armyworm moths captured in East Central Indiana. A prototype ground-based pheromone trap design, baited with various pheromone lures, was field tested for effectiveness in trapping male Agriotes obscurus and Agriotes lineatus click beetles in British Columbia.

Pheromone dispensers containing geranyl octanoate and geranyl hexanoate in a ratio caught the greatest numbers of A. obscurus Cited by: Although the cutworm has the potential for considerable damage, outbreaks are relatively rare.

The crops most severely attacked are maize, vegetables, cotton, tobacco, and turf grasses. An outbreak in Pennsylvania infor instance, decimated ha of maize. Western Bean Cutworm Sampling Protocol.

and John N. King. Abstract. The white pine weevil,Author: René I. Alfaro, John N. King. Introduction. In migratory insect species, individuals that engage in migratory behavior usually undergo changes in their morphological, physiological, and behavioral traits (the so-called "migration syndrome") that facilitate long-duration flight and successful colonization of new habitats (DingleDrake et al.

).An example of morphological changes related to migration is the Cited by: DAMAGE. Cutworms cut young plants off at the base or near the ground level. Usually, it is necessary to dig in the soil to find cutworm larvae and to determine the extent of the infestation and the size of the cutworms involved.

MANAGEMENT. If the cutworm population is reducing the plant stand, treat during the seedling stage. The efficacy of various insecticides and application methods in protecting potatoes from wireworm (Agriotes obscurus L.) damage as well as reducing wireworm populations was studied over 5 yr in Agassiz, British tion from wireworm damage was measured by the number of blemishes to daughter tubers, and effects on wireworm populations were measured by sampling soil Cited by: Full text of "Journal of the Entomological Society of British Columbia" See other formats.

M ATERIALS AND M ETHODS   Army Cutworm Moths (Euxoa auxiliaries), like a lot of insects, are very proficient reproducers. In fact, individual females can settle into the soil and oviposit, or lay, anywhere from to eggs (Burton et al. This release of eggs marks the end of a long, spectacular journey for the adult moths.

Researchers at the University of British Columbia have shed new light on how mountain pine beetles produce an important pheromone called trans-verbenol, which could aid in efforts to better predict outbreaks. In recent years, mountain pine beetles have destroyed more than 25 million hectares of pine forests in western North America.

Forty-two forensic entomology cases, from human death investigations in British Columbia, (B.C.) were analyzed. The insects collected from the remains were identified based on species.

Pink bollworm, Pectinophora gossypiella (Saunders), continues to be a significant pest of cotton worldwide. Two factors essential for effective integrated pest management (IPM) programs for pink bollworm include: 1) quantification of damage-yield relationships, and economic injury levels, and 2) practical sampling plans for estimating pest density, or classifying the pest population above or Cited by: 5.

Larvae of both commonly feed on plants at night, hiding in or on the soil surface under leaf litter by day. Newly emerged males ofHyphantria cunea (Drury) (Lepidoptera: Arctiidae), marked with different fluorescent colors, were recaptured by pheromone trapping.

The symptoms of feeding damage by armyworm larvae include skeletonized grass leaves due to feeding by newly born larvae or entirely consumed grass leaves by mature larvae. is a FREE service to buy and sell used textbooks. You can save a lot of money.
