“…Brießy, just before pupation, larvae move out of the diet and into a waxed, corrugated paper ring Þtted into the top of each rearing dish. After Ϸ80 Ð90% of the larvae within each ring pupated, the rings were harvested and hanged in 4 Ð 6 emergence cages similar to those described by Showers et al (1989a). These cages each held Ϸ44 rings and each ring contained from 400 to 600 pupae.…”

“…Two pupal rings were placed within each of two modiÞed (with a ßoor) Texas 70 Ð50 cm cone traps (Hartstack et al 1979) stationed at the release site. Adults captured in the receptacle placed above the cone were classiÞed as capable of ßight only if there were no abnormalities similar to the abnormalities for Agrotis ipsilon (Hufnagel) described by Showers et al (1989a). Capture data were extrapolated to the numbers of adults emerging from the adjacent release cages.…”

To observe the aggregation and dispersal behavior of adult European corn borer, Ostrinia nubilalis (Hub ner), males in search of mates, two populations were marked, each with a different dye. One population was continuously reared in the laboratory (.5 yr) and the other was collected annually from the Þeld. From 1986 to 1988, marked adults were released in two release sets per year, with three to Þve releases per release set, coinciding with the spring and summer ßights of European corn borer in central Iowa. Traps for recapture contained lures baited with 40 mg of synthetic 97:3 Z:E-11-tetradecenyl acetate. Traplines extended from 200 m to 48 km. Each trap was assigned a compass direction. Males from the laboratory-reared population dispersed similarly to males just 1 generation from the wild. European corn borer males and females dispersed 23Ð49 km and some were recovered 14 km from the release site within 100 min after release. Sampling of aggregation sites demonstrated that on the nights of release, many adults aggregated in adjacent dense vegetation and did not disperse until the following night. Upon dispersal, these adults seemingly moved many meters or kilometers before settling again. Recapture of marked adults at 200 m might have been inßuenced by open landscapes (short, vegetative-growth corn). Recapture at 800 m or beyond, however, was unaffected by open landscapes, and in 1988 a greater proportion of marked males was recaptured while the landscape was closed. (tall, mature-growth corn). In 1987, during the Þrst ßight of European corn borer, displacement to 800 m was southeasterly, south, or west, but during Þrst ßights in 1986 and 1988, displacement to 800mwas predominately northeasterly. During the second ßight in midsummer, displacement to 800 m for all 3 yr of the study also was northeasterly. Recapture results from 1986 suggest that male movement.800mis common. During the Þrst release set (early summer), 37% of the males recaptured ßew 800 m or more and 8% ßew 3.2kmor more. During the second release set (late summer), 51% of the males recaptured ßew 800m or more and 11% ßew 3.2 km or more. The recommendation for placement of nontransgenic corn (Zea mays L.) as refuge in the Corn Belt is a half mile or closer to Bacillus thuringiensis Berliner (Bt)-corn if the refuge corn is not sprayed and a quarter mile or closer when the refuge corn is sprayed. Based on the dispersal results from this study, at least in Iowa, a half-mile proximity recommendation should be robust. Studies still should be conducted in other regions, especially where corn is commonly irrigated, to determine whether European corn borer adult movement patterns are similar. During the second ßight in midsummer, displacement to 800 m for all 3 yr of the study also was northeasterly. Recapture results from 1986 suggest that male movement Ͼ800 m is common. During the Þrst release set (early summer), 37% of the males recaptured ßew 800 m or more and 8% ßew 3.2 km or more. During the second release set (late summer), 51% of the m...

“…Oil-soluble dyes have been used to mark insects in the sterile insect release method (Steiner 1965, Schroeder et al 1974, in area-wide pest management programs Landin 1966, Hendricks et al 1971), and recently, in dispersal studies associated with resistance management programs in transgenic crops (Hunt et al 2001, Showers et al 2001, Qureshi 2003. Dyes have been used to mark insects in the following orders: Coleoptera (Gast and Landin 1966, Lloyd et al 1968, Daum et al 1969, Lepidoptera (Graham and Mangum 1971, Jones et al 1975, Ostlie et al 1984, Ramaswamy et al 1985, Showers et al 1989, Hunt et al 2000, Diptera (Steiner 1965, Schroeder et al 1974), Isoptera Mention of trade names or commercial products in this article is solely for the purpose of providing speciÞc information and does not imply recommendation or endorsement by Kansas State University or the U.S. Department of Agriculture.

“…The use of dyes incorporated in the diet has a key advantage over other marking techniques in that expensive equipment is not needed to identify marked insects. However, for some dyes and some insects, the specimen may need to be crushed (Coppedge et al 1979, Showers et al 1989 or liquiÞed in a solvent (e.g., acetone) before visual or spectroscopic observations are made (Argauer and Cantelo 1972). The dyes do not effectively mark all insects, and not all insects can tolerate the dyes, so preliminary evaluations are needed to verify the efÞcacy of each marker dye for use with each insect species.…”
