Summary: The introduction of the Ae. aegypti red-eye genetic sexing strain (GSS) and recombination suppressing inversion (Inv35) into the Pakistani genomic background was evaluated. The sexing features and recombination suppression properties were not affected, but some biological traits of the newly constructed strains were affected. Quality control analysis is necessary before applying GSS in sterile insect technique (SIT) field trials or applications.

Summary: Exposure to synthetic pheromones increases calling frequency in female swede midges but decreases their propensity to mate, potentially impacting the efficacy of pheromone-mediated mating disruption systems. Further research is needed to fully understand the implications of female autodetection for swede midge management.

Summary: This study investigates the effect of genomic background on the efficiency of the sterile insect technique (SIT) using Ae. aegypti genetic sexing strains (GSS). The results show that the genomic background does not negatively affect the inversion result, indicating that the key elements of the GSS can be introgressed into the local genomic background. This finding has implications for improving the application of SIT and addressing regulatory concerns.

Summary: Fluctuating Thermal Regimes (FTR) have been proven effective in extending the longevity and generation time of fruit flies, with no increase in mortality. By using FTR, pupation time of fruit flies was extended from 4 days to 8 weeks, and mean adult longevity was increased from 12 days to 50 days, reducing the resources needed for maintaining rare and exotic insects.

Summary: This study found that manipulating quorum sensing mechanism in Wolbachia can alter the density of the microorganism and the proportion of hatched eggs in the agricultural pest, thereby reducing the number of insect progeny. These findings provide evidence supporting the potential efficacy of environmentally friendly control of insect pest populations based on cytoplasmic incompatibility (CI)-Wolbachia.

Summary: This study proposes a non-smooth Filippov model to examine the interaction between wild and sterile mosquitoes. By simulating the conditions for releasing sterile mosquitoes and adjusting model parameters such as the threshold value, our findings suggest that lowering the threshold value to an appropriate level can enhance the control of wild mosquitoes, and employing SIT with a threshold policy control can improve economic outcomes while inhibiting disease spread.

Summary: The yellow fever mosquito, Aedes aegypti L., is capable of transmitting various human pathogens. With increasing concerns over insecticide resistance, alternative control strategies for Ae. aegypti are necessary. The sterile insect technique (SIT) has been explored as a popular option, but logistical challenges in mass production and sterilization have hindered its implementation. This study demonstrates that irradiating adult male mosquitoes can improve the efficiency of SIT programs, providing a viable alternative to the traditional pupae irradiation method.

Summary: This study assessed the impact of chilling temperature and exposure period on the quality parameters of sterile Queensland fruit fly. Flies chilled at 4 degrees Celsius took longer to recover compared to those chilled at 6 degrees Celsius, and flight ability, survival under nutritional stress, and longevity decreased with increasing chilling period. There was no significant difference between the two tested temperatures in terms of quality parameters.

Summary: The sterile insect technique is a promising method for mosquito control, but its effectiveness can be influenced by adult mosquito predation. This study investigates the predation propensity of mantis and gecko species on mosquitoes and evaluates the effects of different treatments on predation rates. The selected predators effectively preyed on all mosquito species regardless of the treatment, and predation propensity varied over time and between individuals. The laboratory treatments of sterile males did not have an impact on the relative risk of predation by the predators, unless exposed to double the required sterilizing irradiation dose.

Summary: This study assembled and organized tsetse and AAT data collected in Burkina Faso between 1990 and 2019, creating a digital repository. The distribution of tsetse flies was mapped at the level of individual monitoring traps or locations, while the occurrence of AAT was mapped at the level of locations or villages. Results showed the presence of four tsetse species in Burkina Faso, with Glossina tachinoides being the most widespread and abundant species. AAT was found in all surveyed departments, including tsetse-free areas in the north, with Trypanosoma vivax and T. congolense infections being the dominant ones.

Summary: Reproductive sterility is crucial for the success of the sterile insect technique, and the interaction between dose and dose rate has significant effects on irradiated mosquitoes. The study found that dose rate not only alters the radiation-induced effects, but also that the interaction is non-linear and may vary with dose.

Summary: Effective control strategies, such as the sterile insect technique, play a crucial role in preventing the spread of vector-borne diseases. However, current sex separation techniques for mosquito vectors are not completely effective, resulting in increased risk of disease transmission. This study examined the transmission of dengue and chikungunya viruses in two Aedes species exposed to irradiation, and found that irradiation did not impact transmission efficiency.

Summary: This study aimed to identify the best trapping strategy for catching Ae. aegypti mosquitoes. The use of CO2 alone was found to increase the detection probability and apparent density of Ae. aegypti and Cx. quinquefasciatus mosquitoes. Traps with BG-Lure-alone or in combination with CO2 did not improve the detection probability. For male Ae. albopictus and female Ae. albopictus, neither CO2 nor BG-Lure had a significant effect on their trapping. The apparent densities of Ae. aegypti and Ae. albopictus mosquitoes were similar in both study sites.

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.

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: Four new transgenic sexing strains have been developed to identify and sort male and female Aedes mosquitoes using fluorescence markers linked to the sex-determining loci. These strains provide a more efficient and cost-effective method for controlling disease vectoring mosquitoes. They enable faster and more accurate sex separation, allowing for the production of non-transgenic males. This technology can greatly enhance control programs against these important vectors.

Summary: African animal trypanosomiasis is a vector-borne disease that causes significant livestock losses in sub-Saharan Africa. In our study, we evaluated the effect of irradiation on the fecundity of Glossina palpalis gambiensis, a major vector of this disease, to identify the optimal dose for inducing sterility while maintaining biological performance. The results showed that a dose of 120 Gy induced 97-99% sterility in male tsetse flies after mating with virgin females.

Summary: Balancing process efficiency and adult sterile male biological quality is crucial in the success of the sterile insect technique against insect pest populations. For SIT against mosquitoes, optimizing the irradiation step and considering dose fractionation can significantly improve male mating competitiveness. Fractionating the dose showed positive effects on male longevity and mating competitiveness, but the added labor in SIT programs for mosquito vector management may not outweigh the benefits.
