Wireworm Control, 1988

Insecticide and Acaricide Tests, 1989
Abstract Three plots were established in fields that required replanting because of wireworm damage. The seedbed was prepared by field cultivating out the reduced stand in the severely damaged area of the fields. The experimental design was a randomized complete block with 4 replicates.

Control of Wireworm

Nature, 1946
Thomas and Jameson1 state that as a result of the application of ‘Gammexane’ in field trials reductions in wireworm populations of up to 65 per cent have been obtained. Numerous similar trials were laid down by the Cambridge Advisory Centre in the spring of 1946, in conjunction with Imperial Chemical Industries, Ltd.

Wireworm Management I: Stand Protection Versus Wireworm Mortality With Wheat Seed Treatments

Journal of Economic Entomology, 2009
The efficacy of various insecticidal seed treatments in protecting wheat, Triticum aestivum L., from wireworm damage as well as reducing wireworm (Coleoptera: Elateridae) populations was studied over 3 yr. Protection from wireworm damage was measured by postplanting stand counts, and effects on wireworm populations were measured by within-row core ...

Wireworm damage to wheat seedlings: effect of temperature and wireworm state

Journal of Pest Science, 2012
We describe the results of four laboratory studies designed to measure the effect of temperature and wireworm appetence, weight, and degree of Metarhizium infection on their ability to damage wheat seedlings. Wireworm activity, measured from wireworm speed, increased linearly from 6 to 18 °C and leveled off thereafter.

Mechanical Wireworm Population Sampler

Transactions of the ASAE, 1982
ABSTRACT A mechanical wireworm population sampler was de-signed, constructed and tested for field sampling of wireworm infestations. Depending on soil conditions, this machine can separate at least 70 percent of the par-ticles in the 1 to 4 mm size range. Working details, sampling techniques and field results are discussed.

Studies of wireworm populations

Annals of Applied Biology, 1944
A method has been developed, and is here briefly described, by means of which all the wireworm larvae of all stages can be collected from soil samples. By use of that method, complete wireworm populations have been obtained from soil samples of three types, two of which provide large homogeneous populations for detailed study while the third gives ...

Studies of Wireworm Populations

Journal of Experimental Biology, 1946
ABSTRACT Twenty stations were established in a grass field of 8 acres, and twenty-nine soil samples were examined from each station in the course of 213 years. Wireworms (Agriotes sputator) were distributed among the twenty stations in a non-random manner.

Wireworm Larval Control, 1989

Insecticide and Acaricide Tests, 1990
Abstract Wireworm baits (2-oz mixtures of wheat and corn buried 4 inches deep) placed out in early spring, indicated the presences of wireworms in a field that had received wireworm damage in 1988 (Gilbert location). Another test plot was established in a field requiring replanting because of wireworm damage (Hardy location).

Further Studies on Wireworm Management in Canada: Damage Protection Versus Wireworm Mortality in Potatoes

Journal of Economic Entomology, 2013
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 Columbia. Protection from wireworm damage was measured by the number of blemishes to daughter tubers, and effects on wireworm populations were ...

Wireworm Control in Maine

Journal of Economic Entomology, 1930
The wheat wireworm, Agriotes mancus Say, is a serious pest to Maine crops. An upland species of the genus Melanotus is second in importance. Certain cultural practices and immune crops have been found to be effective in checking wireworm infestations. Meadows and oat fields seem to be favorite breeding grounds for the wheat wireworm.
