“…They attack many important crops, including potato (Parker and Howard, 2001), sweet potato (Seal et al, 1992), wheat (Toba and Turner, 1983), and corn (Kohno and Miyai, 1993). The sugarcane click beetle, Melanotus okinawensis Ôhira, is one of the most destructive insect pests in Okinawa and Kagoshima Prefectures, Japan (Ôhira, 1988;Setokuchi et al, 1990).…”

The dispersal distance of the larvae of the sugarcane click beetle Melanotus okinawensis Ôhira (Coleoptera: Elateridae) in soil was estimated using the mark-recapture method. Grid lines with 30-cm intervals were set 10ϫ10 in a fallow field after sugarcane harvest. Sixty marked larvae were released twice at the center of the grid. The tip of the corneous process on the last abdominal segment was cut and used for marking. Germinating rice seed baits were placed at the 10ϫ10 intersection points of grid lines at a depth of 10 cm in order to recapture larvae. All traps were examined at two-day intervals. The estimate of lifetime natural mean dispersal distance (ϮSE) was 105.6 (Ϯ20.1) cm. The estimate of the natural survival rate per day was 0.861. The diffusion coefficient was estimated to be 613.

Three studies were conducted to determine the effect of preceding crop on wireworm (Coleoptera: Elateridae) abundance in the coastal plain of North Carolina. In all three studies, samples of wireworm populations were taken from the soil by using oat, Avena sativa L., baits. Treatments were defined by the previous year's crop and were chosen to reflect common crop rotations in the region. Across all three studies, eight wireworm species were recovered from the baits: Conoderus amplicollis (Gyllenhal), Conoderus bellus (Say), Conoderus falli (Lane), Conoderus lividus (Degeer), Conoderus scissus (Schaeffer), Conoderus vespertinus (F.), Glyphonyx bimarginatus (Schaeffer), and Melanotus communis (Gyllenhal). The effect of corn, Zea mays L.; cotton, Gossypium hirsutum L.; fallow; soybean, Clycine max (L.) Merr.; sweet potato, Ipomoea batatas (L.) Lam.; and tobacco (Nicotiana spp.) was evaluated in a small-plot replicated study. M. communis was the most frequently collected species in the small-plot study and was found in significantly higher numbers following soybean and corn. The mean total number of wireworms per bait (all species) was highest following soybean. A second study conducted in late fall and early spring assessed the abundance of overwintering wireworm populations in commercial fields planted to corn, cotton, peanut (Arachis hypogaea L.), soybean, sweet potato, and tobacco in the most recent previous growing season. C. lividus was the most abundant species, and the mean total number of wireworms was highest following corn and soybean. A survey was conducted in commercial sweet potato in late spring and early summer in fields that had been planted to corn, cotton, cucurbit (Cucurbita pepo L.), peanut, soybean, sweet potato, or tobacco in the most recent previous growing season. C. vespertinus was the most abundant species, and the mean total number of wireworms per bait was highest following corn.

“…Adhesive red plastic tape was attached to the upper end of the cord to mark trap location. Seal et al (1992) demonstrated that significantly more wireworms were found in the 0-10 cm profiles in bait than in the 10-20 or 20-30 cm profiles; therefore, the traps were placed at the bottom of holes 10 cm deep and 15 cm diameter. The holes were then covered with soil.…”

“…Three rhizome materials known to be susceptible to wireworms were tested (e.g., Seal et al, 1992;Parker and Howard, 2001;Horton and Landolt, 2002): carrot (1 cm cubes), potato (1 cm cubes), and sweet potato (1 cm cubes). In addition, germinated rice seeds were used as bait; rice seed is a readily available material that belongs to the same family as sugar cane, Gramineae.…”

“…Wireworms, the larvae of click beetles (Coleoptera: Elateridae), are worldwide pests of root crops (e.g., Seal et al, 1992;Parker and Howard, 2001), and grain crops (e.g., Toba and Turner, 1983;Kohno and Miyai, 1993). In the Okinawa Islands, Melanotus okinawensis Ôhira (Coleoptera: Elateridae) is the dominant and most destructive insect pest of sugarcane (Hokyo, 1980;Kinjo, 1981, 1990).…”

Bait trap efficiencies were compared to construct a sampling method for wireworms, larvae of the click beetle Melanotus okinawensis (Coleoptera: Elateridae). Various combinations of bait material, bait preparation methods, and bait exposure periods were compared. Wireworms were more efficiently attracted by germinating rice seeds than other bait materials, such as sweet potato, potato, and carrot. Among the bait materials related to rice, germinating rice seeds attracted significantly more wireworms than other materials, such as unpolished rice, polished rice, rice seeds, and rice husks. Rice bran and germinating unpolished rice were lesser attractants than germinating rice seeds. Attractiveness increased only slightly with increasing periods of incubation of rice seeds. Attractiveness increased more slowly with the increase of rice seeds, indicating that 30 g was sufficient for attraction. The number of captured wireworms increased with increasing periods of field exposure, but we judged that three days of exposure might be an appropriate choice because the difficulty of handling traps increased with increasing periods of exposure. Under semiarid soil conditions, bait attractiveness was greatly enhanced by daily irrigation. It was shown that germinating rice seeds with moistened sphagnum moss are as effective as germinating rice seeds with daily irrigation.
