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: The sterile insect technique (SIT) is an environmentally friendly and species-specific method of pest control that involves mass production of target insects in a factory and sterilizing them using irradiation, typically gamma rays. As gamma sources become more difficult and expensive to obtain, and regulations surrounding their use become stricter, there is growing interest in alternative irradiation methods such as X-rays. A recent study found that X-rays can be used effectively to sterilize major SIT target insect species, making X-ray units suitable for small-to-medium-sized SIT programs.

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: The distribution of Aedes albopictus has expanded globally in recent years, increasing the risk of diseases such as dengue, Zika, and chikungunya, which are transmitted by this mosquito species. The sterile insect technique (SIT) has been proposed as an effective method for controlling mosquito populations, and it has been tested in a non-isolated urban area, resulting in a significant reduction in female mosquitoes and eggs. This study analyzes the impact of wild mosquito migration from peri-urban areas to urban cores.

Summary: The study found that there are spatial and temporal differences in male calling behaviors between wild and mass-reared B. tryoni, which may affect assortative mating in SIT applications. Further research is needed to investigate how environmental conditions impact calling behavior and ways to reduce differences between sterile and wild flies.

Summary: Wild populations of An. funestus and An. arabiensis in these study villages can mate both inside and outside human dwellings. Most of the mating clearly happens before the mosquitoes enter houses, but additional mating happens indoors. The ecological significance of indoor mating remains to be determined.

Summary: Since 1990, global egg production has been increasing by an average of 2.8% per year, attracting attention from animal welfare advocates. In Canada, there is a shift towards cage-free egg production systems and increased awareness of animal welfare and environmental concerns. This study assessed the impact of environmental control strategies on egg production and cleanliness in experimental cage-free systems, and developed a machine learning model to predict fluctuations in egg production. The results showed that the strategies did not disrupt egg production and temperature was found to be the most influential factor.

Summary: This study investigated the effectiveness of two indoor residual sprays against malaria-transmitting mosquitoes. The results showed that the clothianidin IRS was highly effective in preventing the spread of malaria, especially against mosquitoes that have developed resistance to other insecticides. The type of surface material also affected the effectiveness of the residual sprays.

Summary: The diel activity patterns of Ae. aegypti in southern Florida and Texas were studied, and it was found that both cities exhibited a bimodal pattern with peak activity in the morning and evening. There were differences in activity patterns on a daily, monthly, seasonal, and site-specific basis, which can be used for planning and implementing vector control activities.

Summary: Resistance to insecticides used to control mosquitoes is likely to develop over time. Monitoring and using alternative insecticide classes are important to sustain the intervention's effectiveness. This study introduces a method for detecting resistance against orally ingested insecticides and suggests using different methods for different modes of uptake. Attractive Toxic Sugar Baits (ATSBs) show promise in controlling resistant mosquitoes, but more research is needed. Monitoring for resistance is crucial, and this study provides a potential method for detection.

Summary: Mosquitoes and the diseases they transmit pose a risk to millions of people worldwide. New methods of vector control are being developed, but public acceptance and local evaluations are crucial for their success. This study highlights the importance of community engagement in mosquito surveillance, control, and ecological projects in impoverished communities along the US-Mexico border. The findings demonstrate that involving community members in the development of communication materials and recruitment procedures improves participation and helps build trust.

Summary: The use of Unmanned Aerial Vehicles (UAVs) has rapidly expanded in ecological conservation, agriculture, and global health efforts including vector control. UAVs offer the ability to reach remote areas inaccessible to ground-based teams, providing a solution to the labor-intensive and slow conventional approaches to vector surveillance and treatment. This review aims to summarize the current knowledge on UAV applications in malaria control and vector control, assess their strengths and challenges compared to conventional methodologies, and explore potential future developments.
