Shoulder dislocations are the most common dislocations and there is a demand for a novel traction device for reducing anterior shoulder dislocations, which can be handled easily without a need for sedation or prolonged observation and recovery. Hence, this research paper proposes a robotic device specifically designed to reduce anterior shoulder dislocation. The device combines abduction and traction techniques to effectively relocate the humeral head into the glenoid fossa and the treatment is primarily based on the Modified Milch Technique, a commonly used technique by clinicians in the Accident and Emergency Departments for shoulder reduction.

The longlegged ant, Anoplolepis gracilipes, is a globally destructive invasive species owning to its devastating impacts on biodiversity and ecosystem functions in the regions where it has been introduced. In Taiwan, invasion of A. gracilipes has been associated with the declining of land crab populations in several hotspots.

Article Synopsis
  • Previous studies identified various coconut free fatty acid (CFFA) compounds that deter egg-laying in different fruit fly species, but results varied.
  • In experiments with the fruit fly Zeugodacus cucurbitae, a CFFA mixture actually increased oviposition, while individually tested compounds had mixed effects—four compounds deterred oviposition, one was neutral, and three stimulated it.
  • A specific blend of the four deterrent compounds proved effective in reducing oviposition, showing both spatial and contact repellency, and has potential for use in pest management strategies since all components are considered safe food additives.

Coconut free fatty acid (CFFA), a mixture of 8 fatty acids derived from coconut oil, is an effective repellent and deterrent against a broad array of hematophagous insects. In this study, we evaluated the oviposition deterrent activity of CFFA on spotted-wing drosophila (SWD; Drosophila suzukii), a destructive invasive pest of berries and cherries, and identified bioactive key-deterrent compounds. In laboratory 2-choice tests, CFFA deterred SWD oviposition in a dose-dependent manner with the greatest reduction (99%) observed at a 20-mg dose compared with solvent control.

Background: Bactrocera dorsalis, oriental fruit fly (OFF), is one of the most destructive agricultural pests. Although bait sprays can effectively control OFF, resistance development has been a concern. We evaluated the oviposition deterrent activity of coconut free fatty acids (CFFA), a mixture of eight coconut oil-derived fatty acids known to repel hematophagous insects and deter their feeding and oviposition, against OFF females.

Global commerce and transportation facilitate the spread of invasive species. The African big-headed ant, (Fabricius), has achieved worldwide distribution through globalization. Since the late 19th century, Taiwan has served as a major seaport because of its strategic location.

Entomopathogenic fungi allow chemical-free and environmentally safe vector management. Beauveria bassiana (Balsamo-Crivelli) Vuillemin is a promising biological control agent and an important component of integrated vector management. We investigated the mortality of Aedes albopictus (Skuse) larvae exposed to five concentrations of B.

is among the most economically significant pests of greenhouse crops, whose resistance to conventional insecticides has created demand for biopesticides such as essential oils. We assessed the fumigant toxicity of linalool against , , and . Thrips were fumigated with polyacrylamide hydrogels containing either ()-linalool, ()-linalool, racemic linalool, or a binary mixture of ()-linalool with one of twelve adjuvants (i.

With heat treatments to control drywood termites (Blattodea: Kalotermitidae), the presence of heat sinks causes heat to be distributed unevenly throughout the treatment areas. Drywood termites may move to galleries in heat sink areas to avoid exposure to lethal temperatures. Our studies were conducted in -infested condominiums in Honolulu, Hawaii to reflect real-world condominium scenarios; either a standard heat treatment performed by a heat remediation company, or an improved heat treatment was used.

Argentine ants are one of the most common nuisance pest ants treated by pest management professionals (PMPs) in southern and western urban residential areas of the United States. Two new technologies (spraying with a pheromone adjuvant and using a biodegradable hydrogel bait delivery method) were used to develop a unique low-impact integrated pest management (IPM) protocol for Argentine ants in urban residential settings. The IPM protocol included a one-time perimeter spray treatment with 0.

Here, we review the literature on the development and application of hydrogel compounds for insect pest management. Researchers have used hydrogel compounds for the past few decades to achieve the controlled release of various contact insecticides, but in recent years, hydrogel compounds have also been used to absorb and deliver targeted concentrations of toxicants within a liquid bait to manage insect pests. The highly absorbent hydrogel acts as a controlled-release formulation that keeps the liquid bait available and palatable to the target pests.

Background: Insecticide sprays used for ant control cause environmental contamination. Liquid bait is a safe and effective alternative, but it requires bait stations to dispense the toxicant. We developed a biodegradable hydrogel to deliver liquid bait obviating the need for bait stations.

Article Synopsis
  • Reproductive division of labor is essential in social insects, with queens focused on reproduction and workers on colony maintenance, but some workers, like those in the yellow crazy ant, can also reproduce.
  • Physogastric workers produce two egg types: reproductive male eggs and trophic eggs that nourish larvae, indicating their role as both reproducers and nutrition providers.
  • The findings suggest that worker reproduction provides benefits such as ensuring food supply during tough times and enhancing genetic diversity through male production which aids the colony’s survival.

This study focuses on the larvicidal, oviposition, and ovicidal effects of a crude extract of Artemisia annua against Aedes aegypti, Anopheles sinensis, and Culex quinquefasciatus. Dried cells of Artemisia annua from cell suspension cultures were extracted using hexane. The extract showed moderate larvicidal effects against mosquitoes.
