“…Results from other articles follow. Bletchly (1961) reported no difference between two dose rates (0.5 and 11.5 Gy/min) at doses (60 Ð 80 Gy) that prevented adult emergence from irradiated Anobium punctatum (De Geer) middle-aged larvae. Gonen and Calderon (1973) found that dose rate was directly related to male reproductive sterility of E. cautella when the doseÐrate ratio was as little as 3:1; egg hatch was 15 and 1% for the lower and higher dose rates, respectively.…”

Phytosanitary irradiation (PI) treatments are promising measures to overcome quarantine barriers to trade and are currently used in several countries. Although PI has advantages compared with other treatments one disadvantage bedevils research, approval, and application: organisms may remain alive after importation. Although this does not preclude their use as a phytosanitary treatment, it does leave the treatment without an independent verification of efficacy and places a greater burden for assuring quarantine security on the research supporting the treatment. This article analyses several factors that have been hypothesized to affect PI efficacy: low oxygen, pest stage, host, dose rate, and temperature. Of these factors, the first is known to affect efficacy, whereas host and dose rate probably need more research. The International Plant Protection Convention considered several PI treatments for its international standard on phytosanitary treatments and did not approve some at first because of perceived problems with the research or the presence of live adults after irradiation. Based on these concerns recommendations for research and dealing with the issue of live adults postirradiation are given. Generic PI treatments are suggested.

“…This shows that the fertility of the irradiated moths of the lesser cotton leaf worm was reduced to a great degree in the females than in the males. Most published reports (BLETCHLY 1961;JAYNES and GODWIN 1957;LINDQUIST 1955;SOKOLOFF 1961) indicate that male insects are more Effects of gamma radiation on the fecundity and fertility of the lesser cotton leaf worm, easily sterilized by ionizing radiation than females of the same species. However, MEYER and MULLER (1961) established that X-ray induced mutation rate in gonia of adult Drosophila sp.…”

Moths of the lesser cotton leaf worm, Spodoptera exigua Hb. were exposed to a wide range (20–100 krad) of gamma radiation. Egg production was decreased by increasing the dose of exposure. Egg fertility was affected by low doses (20 krad) when treated females were mated to normal or treated males. Normal females mated with treated males put few viable eggs at 50 krad. Adult longevity was not affected by gamma radiation up to 50 krad after which the female longevity began to decrease. Zusammenfassung Wirkuhgen von Strahlung auf die Imagines der Baumwolleule Spodoptera exigua (Hb.) Falter der Baumwolleule, S. exigua, wurden mit Strahlen in der Dosierung 20–100 krad behandelt. Mit zunehmender Strahlendosis nahm die Eiproduktion ab. Die Ei‐Fertilität wurde durch niedrig dosierte Strahlen (20 krad) beeinträchtigt, wenn bestrahlte Weibchen von unbestrahlten oder bestrahlten Männchen begattet wurden. Normale Weibchen, die von bestrahlten Männchen (50 krad) begattet wurden, legten Eier verminderter Lebensfähigkeit ab. Die Lebensdauer der Falter wurde erst von Strahlendosen über 50 krad verkürzt.
