The head direction circuit of two insect species

eLife, 2020
Recent studies of the Central Complex in the brain of the fruit fly have identified neurons with activity that tracks the animal’s heading direction. These neurons are part of a neuronal circuit with dynamics resembling those of a ring attractor.

NOVEL PESTECIDES FOR DESERT LOCUST Schistocerca gregaria (Forskal) CONTROL [PDF]

Journal of Plant Protection and Pathology, 2014
The effect of Abamectin and D-limonene was evaluated against desert locust nymphs under laboratory and field conditions, as well as the combined effect of both insecticides with the fungus Metarhizium anisopliae var.

Cellulolytic Bacillus species isolated from the gut of the desert locust Schistocerca gregaria

Scientific African, 2021
The ability of many insects to thrive on wood, foliage, and detritus has stimulated an interest on the potential use of gut microbial flora of such species as a bioresource for industrial conversion of cheap cellulosic material into bioproducts.

Adult Desert Locust Swarms, Schistocerca gregaria, Preferentially Roost in the Tallest Plants at Any Given Site in the Sahara Desert

Agronomy, 2020
The desert locust, Schistocerca gregaria, is a major migratory pest that causes substantial agricultural damage. Flying adult swarms disperse widely during the daytime, but they densely roost on plants at night.

Microbiome‐mediated chemical communication in insects: Implications for pest management

Pest Management Science, EarlyView.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

Precopulatory behavior and sexual conflict in the desert locust [PDF]

PeerJ, 2018
Studies of mating and reproductive behavior have contributed much to our understanding of various animals’ ecological success. The desert locust, Schistocerca gregaria, is an important agricultural pest.

LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus

Insect Science, EarlyView.
The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.

The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks

Agricultural and Forest Entomology, EarlyView.
Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive
