Summary: The study investigated the effects of different strains, larval diets, and sexing tools on the application of the sterile insect technique (SIT) against Aedes albopictus. The adoption of the Fay-Morlan separator increased productivity and limited female presence. The IAEA-BY diet showed the lowest female contamination. Strains with a high number of breeding generations had decreased productivity and increased female presence. Increased female presence was found only in extensively reared strains and when sorting was conducted with sieves. We hypothesize that extensive colonization may reduce size and limit the efficiency of the sexing tool.

Summary: This study shows that an integrated control program consisting of community participation, door-to-door intervention, and the sterile insect technique can effectively control the population of Aedes albopictus. The use of Bacillus thuringiensis israelensis-based fizzy tablets and water-dispersible granular formulation is the most effective intervention in reducing the population, while the mass release of sterile male mosquitoes also yields good results.

Summary: Diseases transmitted by Aedes mosquitoes are a growing global concern. The Sterile Insect Technique (SIT) is a strategy for controlling mosquito populations, and egg storage is essential in SIT programs. This study found that two moisturizing substances, hydrolyzed collagen and Hyalurosmooth(R), can prolong the viability of Aedes mosquito eggs, showing promise in mass rearing insect production for vector control.

Summary: This study investigated the use of nitrogen in the irradiation of adult Aedes albopictus and Ae. aegypti. The results showed that nitrogen treatment improved the longevity of irradiated males but slightly reduced their flight ability. Nitrogen treatment was found to be a reliable method for adult mosquito immobilization.

Summary: This study investigated the effects of ionizing radiation on the survival, longevity, mating behavior, and sterility of Ae. aegypti mosquitoes. The results showed that a radiation dose of 50 Gy rendered males 99% sterile while maintaining mating competitiveness against unirradiated males. Females were completely sterilized at 30 Gy.

Summary: This study aims to standardize the use of a rapid quality control flight test device and provide affordable, practical quality control tools for successful implementation of the sterile insect technique. Factors such as tube color, lure and fan use, mosquito species, and mosquito age and density were found to significantly impact escape rates. A cheaper version of the device was also designed and validated.

Summary: This study developed and assessed a novel method for long-distance shipments of sterile male mosquitoes from the laboratory to the field. The new mass transport protocol allowed the successful shipment of 50,000 sterile male mosquitoes for up to four days, maintaining good survival rates and flight ability. This novel system can be used worldwide for shipping sterile males for journeys of two to four days.

Summary: This study compared the effectiveness of three larval diet recipes for the rearing of male Asian tiger mosquitoes, and evaluated economical feeding alternatives. The results showed that the MIX-14 diet had the best performance and lowest cost, making it a potential replacement for the expensive IAEA-BY diet.

Summary: Strategies to suppress mosquitoes by rearing and releasing male mosquitoes are gaining attention. Different approaches include radiation-based sterile insect technique, Wolbachia-based technologies, and genetic modification. Centralized rearing and shipment of adult males have been used, but the fragile nature of adult males and the requirement for expensive shipment pose challenges. Alternatively, desiccated mosquito eggs can be stored and shipped easily. A model using centrally produced eggs mailed to satellite rearing facilities was examined, showing similar outcomes at different sites for both species.

Summary: Aedes albopictus, responsible for transmitting diseases like dengue, Zika, and chikungunya, is being controlled through the sterile insect technique (SIT) in a pilot project in Spain. The evaluation of irradiated males and quality control parameters in rearing activities are essential for a successful integrated vector management program. This study highlights the potential of SIT as an effective, environmentally friendly control tool against mosquito populations.

Summary: Global trade globalization has led to the spread of species in new regions, causing concerns about the transmission of arboviruses by invasive mosquito species. Current vector management measures are ineffective against urban mosquitoes, and insecticides are losing effectiveness due to resistance. Genetic control methods, such as the sterile insect technique, show promise but require significant investments and regulatory frameworks to be clarified.

Summary: A recent study detected the presence of ISV WSLV4 in Aedes albopictus females in Sao Paulo, Brazil, marking the first detection of this virus in Latin America. The use of next-generation sequencing metagenomics allowed for the discovery and characterization of new insect-specific viruses. Further research is needed to understand the role of Aedes albopictus in the transmission of arboviruses in the Americas.
