Newly emerged male and female adult cactus moths, Cactoblastis cactorum (Berg), were treated with increasing doses of gamma radiation, and the moths were outcrossed to fertile counterparts. Fecundity of the moth pairs was not affected by increasing doses of radiation. The minimum dose at which treated females were found to be 100% sterile when mated to untreated males was 200 Gy. Fertility of treated males declined with increasing doses of radiation to approach 0% near 500 Gy. Inherited effects…

Flight Phenology of Male Cactoblastis cactorum (Lepidoptera: Pyralidae) at Different Latitudes in the Southeastern United States
TLDR
Initiation and timing of the 3 generational flights has importance in the current United States and Mexico monitoring program for presence and expansion of this invasive pest, development of mapping programs to identify monitoring windows and management efforts with the Sterile Insect Technique.

Inherited sterility in Cactoblastis cactorum (Lepidoptera: Pyralidae)
TLDR
Newly emerged male and female adult cactus moths, Cactoblastis cactorum (Berg), were treated with increasing doses of gamma radiation, and the moths were outcrossed to fertile counterparts, and a shift in the F1 sex ratio in favor of males was not observed.

Comparative egg maturation was observed between fertile eggs laid by unirradiated females, by unirradiated females mated with irradiated males, by irradiated females mated with normal males, and by
Inheritance of partial sterility in progeny of irradiated males of Ephestia cautella (Lepidoptera: Pyralidae) and its effect on theoretical population suppression.
One-day-old P 1 males of the almond moth, Ephestia cautella (Walker), were irradiated with 5, 10, 15, or 2 krad of gamma radiation and paired with untreated virgin females. Progeny were collected
Fall Armyworm (Lepidoptera: Noctuidae): Comparison of Inherited Deleterious Effects in Progeny from Irradiated Males and Females
TLDR
Effects of radiation on P1 reproductive ability were greater for irradiated females than for irradiate males; however, inheritance of deleterious effects was greater for progeny from irradiated males.
Effect of Low Doses of Gamma Irradiation on Reproduction of Male Pink Bollworms and Their F 1 Progeny
When adult male Pectinophora gossypiella (Saunders) less than 24 hours old were irradiated with 2.5, 5.0, 7.5, 10.0, or 12.5 krad of gamma irradiation and caged with virgin untreated females, the
Applications of F1 sterility for research and management of Cactoblastis cactorum (Lepidoptera: Pyralidae)
TLDR
The use of inherited (F1) sterility in Lepidoptera to study, predict, and manage the expanding populations of C. cactorum is discussed and research areas in which the use of F1 sterility would be most applicable include.
DISTRIBUTION AND DISPERSAL OF CACTOBLASTIS CACTORUM (LEPIDOPTERA: PYRALIDAE), AN EXOTIC OPUNTIA-FEEDING MOTH, IN FLORIDA
TLDR
The recent arrival of Cactoblastis cactorum Berg in Florida has raised concern for Florida's native Opuntia cacti, and over time there may expect to see a reduction in the number of plants as a result of an increase in the mortality rate of recruits.
The Exploitation and Conservation of Resources by Populations of Insects
TLDR
The present paper supports the idea that the nature and importance of intrinsic regulatory mechanisms may depend on the degree to which the size of an animal population is capable of influencing the quantity of limiting resources available to later generations.
