“…The invasions are unpredictable; the dryland environment of sandy soils, short trees, and warm temperatures triggers their unwelcome landing. As such, fluctuations in soil moisture are often associated with a locust hatching period [1], and semi-arid areas that receive less than 200 millimetres of annual rainfall provide a suitable habitat [2,3]; in addition, swarms roost for the night in trees or bushes [4]. The locusts have the ability to quickly reproduce and unidirectionally migrate to new and old areas, including the greenness of above-ground biomass [5].…”

Desert locust invasions are still a danger to the well-being of natural and man-made ecosystems in the tropics. This study examined desert locust invasion duration, survival probability, and control as well as their effects on household food item consumption in the drylands of Uganda. Primary socioeconomic data were collected using various methods (household survey, focus group discussion, and key informant interviews) in May/June 2020 to document the perceptions of households regarding locusts. Our findings reveal that the most significant drivers of desert locust invasions were rainfall, surface temperature, strong winds, soil moisture, soil type, and vegetation type (p ≤ 0.05). The locusts lasted between 3 and 4 weeks. The survival probability of locusts beyond 1 week was 90%. There were significant differences in the day’s food items consumed before and after the locust invasion, except for ground nuts and cashew nuts (p ≤ 0.05). The number of days per month the food items were consumed decreased after the locust invasion. The most effective locust control measure undertaken was the use of ground and aerial pesticide spraying. The major sources of desert locust control information were radio and television. This information is a prerequisite in desert locust invasion preparedness, response, and recovery but can also strengthen sustainable green economy efforts, especially in fragile semi-arid ecosystems.
