Article Synopsis
  • ! The study examined common beetle pests in two flourmills over one to two years using pheromone-baited traps to understand their distribution and activity in relation to fumigation treatments.
  • ! In flourmill 1, one specific beetle species was the most frequently trapped, while in flourmill 2, two other species were captured more frequently; overall captures increased in the second year likely due to trap modifications.
  • ! Fumigation treatments reduced beetle captures, but didn’t eliminate populations completely, suggesting that they may have been ineffective or that new beetles were entering the mills shortly after fumigation.

A series of laboratory and field experiments were performed to assess the responses of (Herbst) and other stored-product beetles to pheromone-baited traps and trap components. A commercial pitfall trap called the Flit-Trak M, the predecessor to the Dome trap, was superior in both laboratory and field experiments over the other floor trap designs assessed at capturing walking . In field experiments, (L.

Traditional sources of carbon dioxide (CO₂), dry ice, and compressed gas, were tested against 3 combinations of food-grade reagents known to generate CO₂using a compact, lightweight generator delivery system with Centers for Disease Control and Prevention light traps. Three 6 × 6 Latin square trials were completed near the Florida Gulf Coast in the Lower Suwannee Wildlife Refuge during the summer of 2013, collecting a total of 31,632 female mosquitoes. Treatments included dry ice, compressed CO₂gas, a control trap (no CO₂), citric acid + sodium bicarbonate, vinegar + sodium bicarbonate, and yeast + sugar.

Leishmaniasis caused by Leishmania infantum is a complex zoonotic disease, resulting in cutaneous and visceral manifestations in both dogs and humans. The present study involved a published Taqman fluorogenic real-time polymerase chain reaction (PCR) assay for surveillance of Leishmania sp. parasites among sand flies trapped in two provinces in Sicily, Catania and Agrigento, during the summer and fall of 2003.
