Novel natural product based anti-anxiety therapy and natural insecticides
The EtOH extracts of the leaves of Margraviaceae, a relatively rare Central American vine for which ethnobotanical reports suggested possible anti-anxiety properties, showed significant anti-anxiety activity in animal models for anxiety. Subsequent bioassay-guided fractionation of these extracts …

Effects of insecticides on potato leafhoppers Empoasca fabae (Harris) and its predators
Selected insecticides were evaluated to determine effects on the potato leafhopper and its predators. Three types of tests were conducted. First, the common predators of the potato leafhopper in alfalfa were examined to determine their response to the stages of the leafhopper. Second, under field …
