Three-layered functionally specialized nest structures enhance strength and water retention in mounds of Globitermes sulphureus (Blattodea: Termitidae).

Termite mounds are a ubiquitous feature of savanna ecosystems, yet the mechanisms by which termites (Blattodea: Termitoidae) mitigate the challenges posed by seasonal drought and flooding through mound construction remain insufficiently explored. This study investigates the material properties, water retention capabilities, and resistance to raindrop penetration across three distinct layers of Globitermes sulphureus (Haviland, 1898) (Blattodea: Termitidae) nests. Our findings reveal a pronounced diversification and specialization of materials and functions across these layers.

Efficacy of plant-based products and nonconventional pesticides for the management of tropical bed bug.

Insecticide resistance is widespread in global bed bug populations. Both common bed bugs and tropical bed bugs are pyrethroid-resistant among most field populations. Plant-based products and nonconventional pesticides offer minimal-risk strategies for managing bed bug resistance, but this strategy has yet to be formally evaluated in Cimex hemipterus (F.

Analysis of Essential Oils Components from Aromatic Plants Using Headspace Repellent Method against Mosquitoes.

This research serves as the basis for developing essential oil-based repellent activity tests against mosquitoes. The method used for the isolation of essential oils was the steam distillation method. Virus-free mosquitoes were used as test animals by applying the 10% essential oil repellent on the arms of volunteers.

Termite Assemblage and Damage on Tree Trunks in Fast-Growing Teak Plantations of Different Age: A Case Study in West Java, Indonesia.

We conducted surveys of termite assemblages and tree trunks damaged by termites in teakwood ( L.f.) plantations.

Influence of Age and Mating Status on Pheromone Production in a Powderpost Beetle (Coleoptera: Lyctinae).

Powderpost beetles such as are a common pest group for dried cured wood, causing significant harm to wood and wood products. We examined the life span and effects of aging and mating status on pheromone production in the powderpost beetle (Coleoptera: Lyctinae). Experiments compared starved and unstarved male groups, and chemical analysis was used to determine factors affecting pheromone production.
