Summary: The desert locust, one of the most harmful migratory pests, poses a major threat to agricultural production and food security. This study explored the distribution and driving factors of desert locusts using ensemble distribution models. Climate was found to be the most important factor influencing their distribution, and their climatic niche remains conservative. This research provides important insights for preventing desert locusts from settling in invasion areas.

Summary: This study demonstrated the efficacy of four different entomopathogenic fungal formulations against desert locusts in laboratory, greenhouse, and field conditions. Green Muscle showed the highest effectiveness, reducing pest populations and proving potential for integrated pest management programs.

Summary: Despite intensive management measures, locusts pose a periodic threat in Africa, resulting in significant yield loss and corresponding food and financial loss. Laboratory assessment revealed that the toxicity of Photorhabdus luminescens bacteria and its cell-free filtrate caused higher mortality in second and fifth instar locust nymphs. Treated locusts exhibited drastic reductions in protein, fat, and carbohydrate levels. Adverse effects on the muscular layers of the midgut and jumping legs were observed in the treated desert locust nymphs.

Summary: This study investigates the ultrastructural changes in the fat body of fifth instar nymphs Schistocerca gregaria treated with zinc chromium oxide nanoparticles. The nanoparticles were prepared and characterized, and the optical measurements were conducted. The TEM images showed that the fat body was strongly impacted by the nanoparticles, resulting in chromatin agglomeration in the nucleus and malformed trachea in the haemoglobin cells.

Summary: Vitellogenins are important protein precursors found in animals, playing a vital role in the development and reproduction of insects. The expression of vitellogenin A and vitellogenin B in the desert locust is primarily regulated by the juvenile hormone receptor, with high expression levels in adult females.

Summary: The study measured morphological characteristics of different locust populations and found significant differences between the southern and northern populations, suggesting a possible evolutionary dichotomy that could separate them into distinct species.

Summary: The hatching behaviors of the desert locust and the Bombay locust were observed to analyze the mechanisms controlling hatching time and synchrony. Both species showed differences in hatching patterns under different temperature conditions. Interactions between embryos may play a role in controlling hatching, and a vibrational stimulus may be responsible for synchronized hatching.

Summary: The regulation of male reproductive organ development in insects is still an open question, with little known about the effects of phase and pheromones on this process. This study found that the width of follicles and accessory glands in desert locust males is significantly associated with phase, and exposure to pheromones from mature adults can promote the development of these organs.
