“…However, this "alternative" procedure may be challenging both at the application and regulatory level. Interestingly, and similar to the abovementioned study on H. halys, Horrocks and colleagues (2020) [23] show that the application of an irradiation dose of 16 Gy or higher could sterilize male green vegetable bug Nezara viridula, another hemipteran species, by >99%, while females required a dose of 28 Gy to become fully sterile.…”

Although most insect species have a beneficial role in the ecosystems, some of them represent major plant pests and disease vectors for livestock and humans. During the last six–seven decades, the sterile insect technique (SIT) has been used as part of area-wide integrated pest management strategies to suppress, contain, locally eradicate or prevent the (re)invasion of insect pest populations and disease vectors worldwide. This Special Issue on “Sterile insect technique (SIT) and its applications”, which consists of 27 manuscripts (7 reviews and 20 original research articles), provides an update on the research and development efforts in this area. The manuscripts report on all the different components of the SIT package including mass-rearing, development of genetic sexing strains, irradiation, quality control as well as field trials.

“…This should be kept to a minimum in order to preserve the insect's behavior. Laboratory studies on three experimental groups of tsetse fly flies at completely different doses (60Gy, 80Gy, 100Gy, and 120Gy) on mated fertile females revealed that the number of aborted eggs/larvae was directly proportional to the dose [3,11].…”

The sterile insect technique (SIT) is an environment-friendly blighter management technique with application within the area-wide integrated management of key pests, together with the suppression or elimination of introduced populations and therefore the exclusion of recent introductions. Procreative sterility is often evoked by radiation, a convenient and consistent technique that maintains an inexpensive degree of aggressiveness within the discharged insects. The price and effectiveness of an effective program integration of the SIT rely on the balance between sterility and aggressiveness, but it seems that current operational programs with an associate SIT element aren't achieving an associated, applicable balance. In this paper, we will discuss how to improve the sterilization method as well as a simple model and procedure for determining the optimum dose. The work in the gift was focused on an association analysis of the electromagnetic wave technique for insect sterilization as a risk issue. Discharge of enormous numbers of gamma-radiated male flies over the complete island caused concern regarding sterilization as an attainable technique for the dominant insects' public health. Several studies on the sterilization of varied insect vectors of sickness have been conducted since then. The study's goal was to check if electromagnetic waves were an efficient insect management mechanism. Insect sterilization is commonly used to create safe environments for fruit homes, manage blighters, and avoid livestock health issues. The sterilization insect technique entails mass-rearing of the target species, sterilization of the male, and unharnessing in sufficient numbers to equal wild male flies in the natural environment. It's species-specific, with no results for any of the 'non-target' species.

Development of a sterile insect technique as a control strategy for the Asian citrus psyllid: establishing the effect of sterilizing X-rays on fecundity, fertility, and survival

The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama (Hemiptera: Psyllidae), is a major pest of citrus due to its role as the vector of the bacterium that causes huanglongbing. In commercial citrus, ACP control currently relies on the application of insecticides, which may not be sustainable long-term, nor practical in urban areas. The sterile insect technique (SIT) is an alternative strategy in which large numbers of pests are reared, sterilized using radiation, and then released into the field to compete with wild individuals for matings, suppressing population growth. As a fundamental step toward the development of SIT for ACP, this study sought to identify the optimum radiation dose required to sterilize ACP without affecting their survival and mating capacity. Virgin adult ACP of both sexes were subjected to doses of X-ray irradiation ranging from 40 to 480 Gy, then paired with a nonirradiated mate and allowed to produce offspring. Fecundity was estimated as the number of eggs laid, and fertility as the proportion of those eggs that hatched. Females were more radio-sensitive than males, exhibiting a major drop in fecundity at even the lowest dose and 100% sterility at 80 Gy. In contrast, a fivefold higher dose (400 Gy) did not achieve complete sterility in males, with around 5% offspring survival. However, F1 progeny of males exposed to 320 Gy or higher were subsequently found to be 100% sterile. This confirmation of inherited sterility suggests that balancing the sterilizing effects of radiation against its mortality-inducing effects may warrant further evaluation.
