Locusts and other migratory grasshoppers are transboundary pests. Monitoring and control, therefore, involve a complex system made up of social, ecological, and technological factors. Researchers and those involved in active management are calling for more integration between these siloed but often interrelated sectors. In this paper, we bring together 38 coauthors from six continents and 34 unique organizations, representing much of the social-ecological-technological system (SETS) related to grasshopper and locust management and research around the globe, to introduce current topics of interest and review recent advancements. Together, the paper explores the relationships, strengths, and weaknesses of the organizations responsible for the management of major locust-affected regions. The authors cover topics spanning humanities, social science, and the history of locust biological research and offer insights and approaches for the future of collaborative sustainable locust management. These perspectives will help support sustainable locust management, which still faces immense challenges such as fluctuations in funding, focus, isolated agendas, trust, communication, transparency, pesticide use, and environmental and human health standards. Arizona State University launched the Global Locust Initiative (GLI) in 2018 as a response to some of these challenges. The GLI welcomes individuals with interests in locusts and grasshoppers, transboundary pests, integrated pest management, landscape-level processes, food security, and/or cross-sectoral initiatives.

Scelio fulgidus (Crawford, 1911) is a solitary hymenopteran egg parasitoid of the Australian plague locust (Chortoicetes terminifera (Walker, 1870)) and an important contributor to biotic population regulation in its primary host. The history of scientific research on the species is reviewed. Laboratory trials tested a number of aspects of S. fulgidus life history. Development duration from egg to adult was measured over a range of constant temperatures from 18–34°C. Complete development takes 4–6 days longer than C. terminifera embryonic development over the 24–34°C range, but diverges markedly below 24°C. Hatching takes over 300 days at 20°C and development is suspended at 18°C. Single females achieved complete parasitism of host pods in 80% of trials and females can parasitise 3 host pods in sequence. At 25°C, host egg pods were detected and parasitised up to 2 weeks after laying, therefore affecting all locust embryo stages up to and including anatrepsis, the rotation and inversion of the embryo position within the egg. Sibling mating produced male-biased sex ratios in offspring, outnumbering females after 2 generations.
