“…Percent of immigrants varied greatly over time (between years, among field pairs), however, a "baseline movement pattern" was observed that seemed to be independent from all the studied potentially influencing factors and varied around one third of the population (depending on which regression model was taken into account). These findings are in line with Coats et al (1986) reporting that 31% of mated western corn rootworm females performed sustained migratory flight in a flight mill experiment. Similarly, Naranjo (1990) reported that 24% of mated, 2-7 days old females engaged in sustained flight (longer than 20 min) under laboratory conditions.…”

“…Intuitively one would expect a certain rate of dispersal in order to maximize the likelihood of the population's survival. Experimental data are available on the percent of beetles performing sustained flight under laboratory conditions (Coats et al 1986;Naranjo 1990). Field studies identified some external environmental factors as driving forces beyond inter-field movements of adult beetles (Naranjo 1991(Naranjo , 1994Darnell et al 2000;Campbell and Meinke 2006).…”

Dispersal plays a key role in the adaptation of species. It has been suggested that even in a stable and predictable environment, it is essential for any given population to "send" a certain portion of its offspring to disperse (referred as evolutionary stable dispersal rate). Although the literature on the flight behaviour of one of the major maize pests, the western corn rootworm, is rich, relatively little is known about its inter-field movements under field conditions. In the present study, inter-field movement of adult beetles was observed in Central-Europe under quasi-isolated conditions of infested continuous and un-infested first year maize fields, and related to candidate predictor variables. Percent of immigrants (net percent of adults within a given population leaving their natal maize field and arriving in first-year maize) varied greatly across years and locations (0.4-93.3%, mean = 38.7%). Results of the study provided field evidence of the assumption that western corn rootworm performs density dependent inter-field movement. Independent from pest densities, it appeared that about 1/3 of an adult beetle population always leaves its natal maize field, which likely allows the species to find new food sources and oviposition sites. The distance between maize fields and the phenological status of maize influenced inter-field movements but at a much less extent than it could have been expected from laboratory research findings.

“…Revolutions of the ßight arm were sensed by an infrared eye mounted on the central post supporting the pin. Each ßight mill was enclosed by a vinyl tent to reduce air ßow around the adult and artifactual movement of the ßight arm (Clark et al 1984, Coats et al 1986). Twelve (in 2006) or 16 (2007) ßight mills were housed in a walk-in environmental chamber maintained at 24ЊC, 16:8 (L: D), and 80% RH.…”

European corn borer, Ostrinia nubilalis, flight behavior was examined in laboratory experiments. Adults were each tethered to 1 of 16 round-about flight mills in an environmental chamber, and the data were relayed to a computer. Parameters analyzed included duration, distance, and speed of the longest continuous flight and total flight time during an 8-h night. Comparisons were made between unmated and mated adults of both sexes at different ages up to 5 d after emergence. For unmated females, duration of the longest flight was highest the first night after emergence, declining significantly by 5 d of age. In contrast, duration of the longest flight for males was lowest at 1 d of age, increasing significantly by 3 d of age. Flight speed of females was roughly twice that of males at all ages. Mating did not affect flight behavior of either sex at any age tested, but mated adults could not be tested before 2 d of age because the first night was needed for mating. The pattern of age-specific flight behavior suggests that unmated females engage in obligate migratory flight the first full night after emergence. The median duration of this flight was ≈2 h in our experiments, with some adults flying continuously for the full 8 h of darkness. Females of other ages and males of all ages tested were capable of long-duration flights, but they more likely represent foraging flight. These results help explain the high dispersal rate of newly emerged adults from release sites in field experiments.

“…Important factors inßuencing population distributions of corn rootworm beetles are adult mobility and hostplant phenology. Western corn rootworm beetles are very mobile insects with both trivial movement (Naranjo 1991(Naranjo , 1994 and migration (Coats et al 1986, Grant and Seevers 1989, Naranjo 1990) events impacting spatial dynamics over time. When movement occurs among cornÞelds (Hill and Mayo 1980), the majority of the dispersal activity appears to be by females (Hill and Mayo 1974, Godfrey and Turpin 1983, Naranjo 1991.…”
