Article Synopsis
- Balancing process efficiency while ensuring high biological quality of sterile male insects is crucial for the success of the sterile insect technique (SIT) in controlling mosquito populations.
- The production and release of sterile males are affected by several stress factors, including mass rearing, irradiation treatments, and handling procedures, which can impact their competitiveness after release.
- Research into dose fractionation of irradiation, where the sterilizing dose is split into two lower doses, has shown improved male longevity and mating success, though the increased labor involved in applying this technique may not justify the benefits.
Response of male adult mosquitoes to gamma radiation in different nitrogen environments.

Article Synopsis
- The study examines how the developmental stage of mosquitoes influences their reaction to ionizing radiation, focusing on adult males and the challenge of effective irradiation without compromising quality.
- It compares the effects of irradiating mosquitoes in nitrogen (N), in air after nitrogen treatment (PreN), and in air, revealing that higher doses of radiation lead to lower egg hatch rates, particularly in nitrogen environments.
- The findings suggest that nitrogen treatments can enhance the longevity of irradiated males and are effective for immobilization, with PreN emerging as the most efficient method for achieving sterility with minimal impact on male quality and shorter immobilization times.
Background: South Africa has set a mandate to eliminate local malaria transmission by 2023. In pursuit of this objective a Sterile Insect Technique programme targeting the main vector Anopheles arabiensis is currently under development. Significant progress has been made towards operationalizing the technology.

Numerous factors that influence dose-response in insects have been identified. However, historically the radiation dose administered has been considered a constant.

Due to the lack of efficient vaccines, the control of mosquito-borne diseases primarily relies on the management of the vector.

- The Sterile Insect Technique uses radiation-induced sterile males to control pest populations, and effective irradiation protocols are necessary for high-quality sterile insects.
- A study was conducted on Aedes aegypti, Ae. albopictus, and Anopheles arabiensis to evaluate their oxygen consumption in water and examine the effects of radiation in hypoxic versus normoxic conditions.
- Results showed that all species quickly depleted dissolved oxygen in water, with An. arabiensis being the fastest, and that hypoxic conditions provided a protective effect during irradiation, notably more significant in An. arabiensis.
Article Synopsis
- The sterile insect technique relies on producing large quantities of high-quality mosquito eggs for effective biological control, making production efficiency crucial.
- Psocids of the genus Liposcelis, particularly Liposcelis bostrychophila, are identified as pests that feed on stored mosquito eggs in insectaries, where conditions are favorable for their survival.
- The report explores the feeding habits of these scavengers and offers strategies to prevent infestations, ensuring the integrity of mosquito egg stockpiles.
