Comparison of Sticky Wing and Cone Pheromone Traps for Monitoring Seasonal Abundance of Black Cutworm Adults and Larvae on Golf Courses

Abstract

Black cutworm, Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae), flight activity was monitored on three golf courses in Wisconsin by using two types of pheromone traps: the Texas cone trap and sticky wing trap. The Texas cone trap caught significantly more black cutworm males compared with the sticky wing trap, capturing almost 12-fold more males. Black cutworm males were most abundant during mid-July in 2001 and 2002, between 700 and 800 cumulative degree-days. Flight activity also was detected in early May and mid-August, but these peaks were not as pronounced as in mid-July. No definitive relationship between black cutworm flight activity and subsequent larval infestations on golf course putting greens occurred.

Biorational insecticides in pest management

“…100) Although in the vast majority of cases a good correlation between catches and level of damage has been noticed, [101][102][103] sometimes the number of adults caught in traps was not correlated with the number of eggs laid and larvae found in plants. 104,105) In order to get a good prediction of the damage caused by the larvae of the next generation, several features should be considered. Pheromone composition of the bait including dose and purity, both chemical and stereomeric, is the first parameter to bear in mind.…”

Black Cutworm (Lepidoptera: Noctuidae) Flight Activity on a Golf Course in Central Alabama

“…Black cutworm is a migratory species (Showers 1997). In Wisconsin, moths are active in May through late Aug or early Sep (Hong & Williamson 2004), which is similar to the flight pattern observed in other northern areas (Levine et al 1982). However, there is no flight activity during the winter in the northern United States.…”

“…Feeding damage by black cutworm, especially older larvae (i.e., 4~6th instars) creates sunken pock-marks or suppressions, resulting in the reduction of uniformity and smoothness of putting green surfaces (Vittum et al 1999). Although there was no significant relationship between black cutworm adult population and larval infestation on golf course putting greens (Hong & Williamson 2004), monitoring adult population can provide some insight on potential larval activities on putting greens (Potter 1998). Black cutworm is a migratory species (Showers 1997).…”

“…Two sticky traps (TRECE Inc., Salinas, California) baited with cap-type synthetic sex pheromone (TRECE; BCW 3141-25) were installed in trees at ca. 1.5 m above the turf surface (Hong & Williamson 2004) on 7 Apr 2010. The location of traps was less than 20 m from the creeping bentgrass, a preferred host, on putting greens.…”

Insecticidal activity of bio-oils and biochar as pyrolysis products and their combination with microbial agents against agrotis ipsilon (Lepidoptera: Noctuidae)

“…The larva of Agrotis ipsilon (Hufnagel) (Lepidoptera, Noctuidae), commonly known as cutworm, is a serious polyphagous pest of different economic vegetables, field crops and golf course grasses around the world (El-Salamouny et al, 2003;Hong & Williamson, 2004). However, adequate control of this pest with chemical pesticides is difficult to achieve.…”
