“…Rubidium is non-toxic and interchangeable with Na (Berry et al 1972) and K (Stimmann et al 1973;Dulka and Risby 1976). We found no evidence of Rb toxicity in this experiment which parallels findings on cabbage loopers (Stimmann et al 1973), aphids (Frazer and Raworth 1974) Mexican bean beetles (Shepard and Waddill 1976), and pink boll-worms (Van Steenwyk et al 1978). As Rb substitutes biochemically for K, it was surprising to find significantly higher levels of K in Rb-reared male and female flies than in flies from the control rearing (Table 11).…”

Can. ~n t .11 1: 1293-1298 (1979) Elemental profiles of onion maggots reared on a dried carrot based medium were monitored by X-ray energy spectrometry. Adult insects had higher levels of S, Fe, Cu, and Zn and lower levels of C1, K, Br, and Sr than were apparently present in the medium. Addition of Rb to the larval diet resulted in a higher than normal concentration of Rb in the newlyemerged adults. This concentration of Rb decreased to ambient levels after 10 days. When Y was added to the rearing medium, it was not incorporated into the adult flies. Pupae from the Ga-supplemented diet failed to mature. The elemental profiles of male and female adults from the Rb-and Y-rearings differed significantly from the control rearings and each other. X-ray energy spectrometry shows much promise in helping define and monitor mineral requirements in insects.

The potential and propensity in ßight of Pectinophora gossypiella (Saunders) in the laboratory were measured using a 32-channel, computer-monitored ßight-mill system. Females ßew signiÞcantly farther within a 72-h ßight period than did males. The mean accumulated ßight distance and ßight duration of 1-d-old female individuals in a tethered-ßight test were 41.25 Ϯ 7.76 km and 23.87 Ϯ 2.55 h, respectively, whereas for male individuals, the same parameters were 23.46 Ϯ 2.13 km and 14.12 Ϯ 1.12 h. The ßight ability of adults was signiÞcantly positively correlated with pupal weight. The ßight activity of unmated pink bollworm moths increased daily from the time of eclosion, reaching a peak at 3Ϸ5 d and reducing gradually. All the moths could ßy normally at 16Ϸ36ЊC; however, the optimum temperature for ßight ranged from 24 to 28ЊC, whereas the optimum relative humidity ranged from 75 to 90%.

“…Data on dispersal of pests targeted by Bt crops are required to determine optimal distances between refuges and Bt Þelds. Although pink bollworm adults can disperse long distances, previous work suggests that movement of moths is limited when cotton is available (Metwally and Hosny 1974, Van Steenwyk et al 1978, Henneberry and Keaveny 1985.…”

A major challenge for agriculture is management of insect resistance to toxins from Bacillus thuringiensis (Bt) produced by transgenic crops. Here we describe how a large-scale program is being developed in Arizona for management of resistance to Bt cotton in the pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae), and other insect pests of cotton. Financial support from growers makes this program possible. Collaboration between the Arizona Cotton Research and Protection Council, the University of Arizona, and government agencies has led to development of resistance management guidelines, a remedial action plan, and tools for monitoring compliance with the proposed guidelines. Direct participation in development of resistance management policies is a strong incentive for growers to invest in resistance management research. However, more research, regularly updated regulations, and increased collaboration between stakeholders are urgently needed to maintain efficacy of Bt toxins in transgenic crops.
