“…Flight of laboratory-reared C. sinica was recorded with a 32-channel, computermonitored ßight mill system, adapted to monitor the ßight of small insects (Cheng et al 1997, Zhang et al 2008, Lu et al 2009). The ßight mill was composed of a 10-cm-long, 2-mm-diameter revolving copper thread arm, suspended between two miniature magnets ( Fig.…”

“…Other stored-product beetles also have been shown to initiate ßight more readily soon after adult emergence (e.g., R. dominica, Barrer et al 1993, Aslam et al 1994, Dowdy 1994and P. truncatus, Fadamiro et al 1996), but ßight initiation of these other beetles only occurred in very young insects (Ͻ1-wk old or Ͻ2-wkold, respectively) and was rare in older adults, unlike T. castaneum adults that were able to initiate ßight even when 5 mo old. The relationship between age and ßight initiation in T. castaneum is similar to that of many other insects that have the ability to ßy throughout their adult life, for example, the codling moth, Cydia pomonella (Lepidoptera: Tortricidae) (Schumacher et al 1997), Adelphocoris suturalis, A. fasciaticollis Reuter, and the alfalfa plant bug, A. lineolatus (Goeze) (Heteroptera: Miridae) (Lu et at. 2009), and the ragweed beetle, Ophraella communa LeSage (Coleoptera: Chrysomelidae) (Tanaka and Yamanaka 2009).…”

Influence of Age, Mating Status, Sex, Quantity of Food, and Long-Term Food Deprivation on Red Flour Beetle (Coleoptera: Tenebrionidae) Flight Initiation

Effects of age, sex, presence or absence of food, mating status, quantity of food, and food deprivation on rate of and time of flight initiation of the red flour beetle, Tribolium castaneum (Herbst), were determined. Flight initiation declined with increasing age in both presence and absence of food. However, flight initiation was lower when food was present in the flight chambers than in the absence of food. In the presence of food, both mated and virgin beetles were equally likely to disperse by flight. However, in the absence of food, mated beetles initiated flight more readily that virgin individuals. Flight initiation was greatest when little or no food was present. The presence of varying quantities of food inside the flight chambers impacted the number of progeny produced by females before flight, but not the timing of flight. Rate of flight initiation was higher for beetles deprived of food for short periods of time compared with flight initiation of beetles with food in the flight chamber. Flight initiation decreased with increasing time without food. There were no differences in flight tendencies between males and females in the experiments reported here. Our results suggest that T. castaneum uses flight as a mechanism to disperse to new environments during almost any part of their life span and that this type of dispersion does not fit with the model of the so-called true migratory species that involves an "oogenesis-flight syndrome.

“…Flight performance of adult Adelphocoris spp. was greatly affected by age but not by gender, mating status, or oviposition [31]. Mated females of Cydia pomonella exhibited peak flight performance between 1 and 3 d after eclosion, corresponding to the major egg-laying period [32].…”

Onset of Oviposition Triggers Abrupt Reduction in Migratory Flight Behavior and Flight Muscle in the Female Beet Webworm, Loxostege sticticalis

et al. 2016

Flight and reproduction are usually considered as two life history traits that compete for resources in a migratory insect. The beet webworm, Loxostege sticticalis L., manages the costs of migratory flight and reproduction through a trade-off in timing of these two life history traits, where migratory behavior occurs during the preoviposition period. To gain insight into how migratory flight and reproduction are coordinated in the female beet webworm, we conducted experiments beginning at the end of the preoviposition period. We used flight mills to test whether flight performance and supportive flight musculature and fuel are affected by the number of eggs oviposited, or by the age of mated and unmated females after onset of oviposition by the former. The results showed that flight distance, flight velocity, flight duration, and flight muscle mass decreased abruptly at the onset of oviposition, compared to that of virgin females of the same age which did not change over the next 7 d. These results indicate that onset of oviposition triggers a decrease in flight performance and capacity in female beet webworms, as a way of actively managing reallocation of resources away from migratory flight and into egg production. In addition to the abrupt switch, there was a gradual, linear decline in flight performance, flight muscle mass, and flight fuel relative to the number of eggs oviposited. The histolysis of flight muscle and decrease of triglyceride content indicate a progressive degradation in the ability of adults to perform additional migratory flights after onset of oviposition. Although the results show that substantial, albeit reduced, long-duration flights remain possible after oviposition begins, additional long-distance migratory flights probably are not launched after the initiation of oviposition.
