Wireworm damage to wheat seedlings: effect of temperature and wireworm state
Journal of Pest Science, 2012We 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.

Potato, Wireworm and False Wireworm Control, Echo, Oregon, 1977
Insecticide and Acaricide Tests, 1979Abstract The test was conducted in a grower’s center-pivot, sprinkler-irrigated field. The soil type was Ritzville (Calciorthidie Haploxerolls) silt loam; it contained less than 0.5% organic matter. Soil samples (150) taken in a similar adjacent field with a 51/2-in. diam posthole digger to a depth of at least 18 in.

Insecticide and Acaricide Tests, 1989
Abstract Test plots were established near Burley, Idaho. Soil type was Portneuf silt loam and irrigation was by surface flow. Insecticides were applied in a 5-inch band approximately 1 inch under the expected seed-planting level. The soil was opened with a ‘Rus-Ken’ opener and the granules were applied in a 5-inch band inside the opener ...

Insecticide and Acaricide Tests, 1992
Abstract 'Atlantic' potatoes were planted 2 May, near Powells Point, NC, on 42 inch centers. Plots consisted of single rows, 10 ft long, replicated 4 times in a randomized complete block design. Alleys of 10 ft were used between replicates. Treatments were applied with a shaker jar before planting.

Wireworm Management I: Stand Protection Versus Wireworm Mortality With Wheat Seed Treatments
Journal of Economic Entomology, 2009The 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 ...

Studies of Wireworm Populations
Journal of Experimental Biology, 1946ABSTRACT 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.

Nature, 1945
WIREWORMS are undoubtedly the most notorious of all insects of agricultural importance, probably because their depredations are more extensive at times of agricultural expansion and prosperity. The traditional agriculture of Britain has been mainly the type known as 'mixed farming', and the measure of prosperity has been the extent of land under the ...

Insecticide and Acaricide Tests, 1993
Abstract Granular soil insecticides were applied at planting time at a site just north and west of Schuyler in Colfax Co., NE, on 7 May. The soil type was silt loam and the previous crop was wheat. The plot was planted no-till into the wheat stubble into slots previously prepared with the landowner’s planter. Residue cover was heavy. The

INVESTIGATIONS ON THE CONTROL OF WIREWORMS
Annals of Applied Biology, 1927Summary.A study of the wireworm problem in Great Britian shows that this pest is especially important in areas devoted to intensive agriculture and commercial horticulture.In addition to most farm crops, strawberries, various flowers and tomatoes me particularly susceptible to wireworm attack and because these crops 60 often occur on new land, losses ...
