Dominant Lethality

Exposure of the mature pupa or the newly emerged adult of the codling moth, Carpocapsa pomonella (L.), to 40,000 rads of gamma radiation induced dominant lethality in at least 98% of the sperm without affecting adult emergence, mating behavior, or adult longevity. Higher dosages decreased the frequency of mating. Irradiation of eggs, mature larvae, or young pupae induced dominant lethality in a high percentage of the sperm, but caused prohibitively high mortality and frequently reduced mating. The female was more radiosensitive than the male. In general, sensitivity decreased as development progressed from the egg to the adult stage.

The objective of experiment was determinate the radiation dose for disinfestation to mango Mangifera indica cv. Haden, infested by Anastrepha fraterculus larvae. For realization of the experiment, were collected fruits in the field, which were taking to Entomology laboratory where there was a infestation by the flies in cages during 72 hours period. Waited for the development of the larvae and before 5 – 8 days to infestation, the mangos were irradiated in a Cobalt-60 source with doses of: 0(control), 50, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1.100, 1.200 and 1.300 Gy. After the irradiation, the fruits were placed in climate chamber with 25 ±5°C of temperature and 70±5% of relative humidity, posteriorly waited the larvae exit to out of the fruit until the transformation in pupae and posteriorly in adult stage. By the results obtained our can concluded that the lethal dose to larvae in mangoes infested with 5-8 days after infestation were 600 Gy and 1.000 Gy (0.6 and 1 kGy) respectively. The dose of 50 Gy prevented the total adult emergence for both treatments.

The development and reproductive behavior of Mantispa viridis Walker was examined in northwestern South Carolina. Campodeiform first instars actively searched spider egg sacs and halted the development of spider eggs that had advanced to the prelarval or larval developmental stages. M. viridis utilized both viable and inviable spider eggs and completed development on as few as five black widow, Latrodectus mactans (F.), eggs. Developmental time from eclosion to adult emergence averaged slightly less than 24 d. Both mated and unmated females produced egg clutches. However, viable clutches were only produced by mated females. Mated females produced a greater number of clutches each containing more eggs than unmated females. Unmated females produced a small number of eggs that embryonated, and in which a mantispid larva developed. However, larvae in these eggs did not eclose. Males were found to have the intertergal membranes between abdominal segments 3 and 4, and 4 and 5 expanded. These membranes were everted during courtship and apparently emitted a mating or recognition pheromone. Mating behavior and adult longevity are also described.

Immature fifth instar Rhodnius nymphs and adults of both sexes were exposed to various doses of 2 MVP X-rays, chosen to produce reductions in fertility up to and including complete sterility. In male insects irradiated as fifth instar nymphs and reared to the adult stage, sterilizing doses interfered with mating, thus making these males useless as a means of inhibiting the growth of populations into which they are introduced. Exposure in the adult stage, on the other hand, had less effect on mating behavior. Thus, with a very high dose (17,500 r) and high ratios of sterile to fertile males, a substantial reduction occurred in percentage of viable eggs from normal females. However, this was true for the first month only. In the second and third months, the effect on population fertility disappeared, a result of the early deaths of irradiated males. Greater effectiveness in limiting population growth over extended periods might be expected to result from the introduction of males that had been partially sterilized by exposure to lower doses.

This is the third paper in a series dealing with investigations, initiated in 1956, to determine if the codling moth, Carpocapsa pomonella (L.), might be eradicated in the Okanagan and Similkameen Vallevs of British Columbia by the release of sexually sterile moths. In the first twoe papers exposure to heat (Proverbs and Newton, 1962) and to gamma radiation (Proverbs and Newton, 1962a) were examined as methods of inducing sexual sterility. Heat was not satisfactory. However, exposure of fully developed pupae to 40,000 rads of gamma radiation induced almost complete sexual sterility (used in the broad sense) in the male moth without causing undesirable side effects. The female was more easily sterilized than the male.

Regulation Of Cell Cycle

Abstract Although it is well established that plant seeds treated with high doses of gamma radiation arrest development as seedlings, the cause of this arrest is unknown. The uvh1 mutant of Arabidopsis is defective in a homolog of the human repair endonuclease XPF, and uvh1 mutants are sensitive to both the toxic effects of UV and the cytostatic effects of gamma radiation. Here we find that gamma irradiation of uvh1 plants specifically triggers a G2-phase cell cycle arrest. Mutants, termed suppressor of gamma (sog), that suppress this radiation-induced arrest and proceed through the cell cycle unimpeded were recovered in the uvh1 background; the resulting irradiated plants are genetically unstable. The sog mutations fall into two complementation groups. They are second-site suppressors of the uvh1 mutant's sensitivity to gamma radiation but do not affect the susceptibility of the plant to UV radiation. In addition to rendering the plants resistant to the growth inhibitory effects of gamma radiation, the sog1 mutation affects the proper development of the pollen tetrad, suggesting that SOG1 might also play a role in the regulation of cell cycle progression during meiosis.
