Summary: The carcass milling technique (CMT) formulates specific diets for mass production of fish, birds, and animals. It is also used to develop artificial insect diets. CMT diets enhance growth and development without any negative impact and have been successful in producing high-quality insects for other organisms.

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: This study evaluates the potential use of the sterile insect technique (SIT) for controlling Bagrada hilaris. The results show that male insects irradiated at 60 Gy exhibit reproductive behaviors similar to unirradiated males, while those irradiated at 100 Gy show a severe decrease in sexual performance.

Summary: The Sterile Insect Technique (SIT) is an effective control method for the Queensland fruit fly, and reliable insect marking techniques are necessary for successful SIT operations. Variation in fluorescent dye performance has been observed in past Qfly SIT release projects. This study reviews past experience and presents potential alternatives to fluorescent dyes.

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: This study aimed to evaluate insect developmental parameters by comparing food consumption of Spodoptera frugiperda larvae reared with diets of different protein levels under laboratory conditions. The research found that the protein level in the diet influenced the duration of larval and pupal periods, as well as pupal weight, but did not affect larval survival, fecundity, and adult longevity.

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: Research has shown that in different mating systems of insects, bisexual release is most effective for swarm-type mating systems, while for scramble-type mating systems, it depends on the difference in female searching ability between sterile and wild males. The net impact of sterile females depends on the difference in sexual performance between wild and sterile males.

Summary: This study explores the potential resistance evolution in female discrimination against mating with sterile males in the context of sterile insect technique (SIT). The authors find that the evolution of female discrimination is generally too slow to halt population collapse when a constant-release implementation of SIT is used. However, periodic premature cessation of SIT or using a proportional-release protocol can allow discrimination to evolve and prevent extinction if discriminating genotypes exist in the population.

Summary: The study examined the use of stable isotope ratios to distinguish between laboratory-reared and wild Queensland fruit flies. Results showed high variability in delta N-15 values, making it ineffective for discriminating between sterile and wild flies, while measurements of delta C-13 values resulted in 100% correct classification of wild flies and 96.88% correct classification of released flies.

Summary: The study showed that a 5-day pre-release holding period along with provision of yeast hydrolysate (YH) in the diet significantly increased the abundance of mature male Queensland fruit fly. This suggests that providing YH and sugar as pre-release diet, along with a 5-day post-eclosion holding period, is beneficial for the success of SIT programmes targeting the species.

Summary: This study investigated the effects of domestication on quality control parameters of old and young Queensland fruit fly colonies. The results showed that regardless of their origin, older colonies performed better in many parameters. The authors emphasized the importance of considering the effects of continued domestication on quality control measures when setting assessment standards for fruit fly strains used in SIT programs.

Summary: Fruit flies are primarily spread through infested fruit, and the ability to establish a population in a new area is determined by their propagule pressure. By developing a spatially-explicit individual-based model, we identified key factors such as tree density and mating range that influence the establishment probability of the Queensland fruit fly.

Summary: In May 2019, 96 cattle died from Pimelea toxicity in a period of 19 days after potential exposure. The deaths started occurring within 5 days. It is suspected that several factors contributed to these deaths, including recently purchased stock being transported to flooded land containing Pimelea elongata. This weed species contains simplexin and 18 other compounds that are highly toxic, particularly in the roots, flowers, and seeds. It is believed that the thirsty and hungry cattle consumed seeds and roots from the flooded pastures, resulting in lethal doses of simplexin ingestion. Blood tests were found to be unreliable indicators. Management strategies are recommended.

Summary: The study found that storage of particle board blocks did not prevent chemical degradation, with reductions of 25% and 16% in cuelure and malathion contents, respectively, after a short period of use. The most significant changes in chemical contents occurred within the first four months, with reductions of 56% and 35% in cuelure and malathion contents, respectively. Chemical contents and weight of the blocks continued to decrease with long-term exposure, with the edges degrading more than the central core.

Summary: This study found inherited intraspecific variation in sexual signalling in a fruit fly species, Bactrocera tryoni. The abundance of various compounds in male rectal glands showed significant variation among different lines, while no significant variation was found in female rectal glands. The differences in compound abundance were related to both domestication and collection regions, suggesting the involvement of multiple genes.

Summary: Wetlands globally face increasing pressure from climate change, altered flow patterns, and human encroachment. The Landsat satellite imagery archive provides valuable data on how wetlands have responded to these pressures over the past three decades. This paper presents the Wetlands Insight Tool (WIT), a workflow that uses satellite observations to create multidecadal plots of wetland cover types in Australia, allowing for improved evidence-based decision making and facilitating the comparison of ground-based and satellite observations.

Summary: The Host Reproduction Number (HRN) is a useful measure for surveillance, management, and trade of fruit flies. A review of literature on Queensland fruit fly (Qfly) revealed data on 297 hosts, with 81 hosts having HRN data and 216 hosts having no HRN data. HRN can inform target surveillance and management programs, as well as activities related to incursion response management, risk mitigation, and trade options. Consistent reporting of HRN by scientists is necessary for optimizing Qfly management programs and trade protocols.
