Mating disruption in apple orchards: dispenser release rates, generic blends and community impact
… sex pheromone blends and generic blends upon the mating behavior of Platynota flavedana Clemens, Platynota idaeusalis (Walker), Argyrotaenia velutinana (Walker) and Choristoneura rosaceana (Harris) was studied using small plots. It was determined that the sex pheromone blend for P. flavedanamay …

Impact of Low-Spray Mating Disruption Programs on Aphidophagous Insect Populations in Virginia Apple Orchards
… The low-spray blocks employed the use of mating disruption for control of the key direct pests, codling moth, Cydia pomonella (Linnaeus), and leafrollers. The abundance and diversity of aphid predators in low-spray mating disruption programs and conventionally controlled apple orchards was …

Mating Success in Low-Density Gypsy Moth Populations
… studies were conducted to evaluate the effect of mating disruption on the mating success of the gypsy moth, Lymantria dispar (L), in low-density populations. The gypsy moth is an insect pest of hardwood forests in many regions of the world. The discovery of the sex pheromone disparlure …

The influence of pheromone dispenser release rates, trap height and pheromone dispenser height on captures of leafrollers in Virginia apple orchards
… of several designs of pheromone dispensers for mating disruption of leafrollers and codling moth, Cydia pomonella (Linneaus). Release rates were described by linear equations for at least four months, but by the end of the season release rates tended to become erratic. Biocontrol’s red-brown …

Ecological and behavioral factors associated with monitoring and managing pink hibiscus mealybug (Hemiptera: Pseudococcidae) in the southern US
… 50 m from infested source plants. The effects of mating disruption, the insecticide (dinotefuran), the parasitoid, Anagyrus kamali (Moursi), and the predator, Cryptolaemus montrouzieri (Mulsant) on PHM on hibiscus plants in screened field cages were evaluated. The total number of mealybugs …

OPTIMIZING THE BIOLOGICAL CONTROL OF INVASIVE INSECTS: EVALUATING NATURAL ENEMY HOST SPECIFICITY, PREY BEHAVIOR, AND VIBRATIONAL COMMUNICATION
… employed to develop tactics for mass trapping or mating disruption. However, developing such strategies requires studying the substrate-borne vibration of the species in consideration. With the aim of characterizing the substrate-borne vibrational communication that mediates courtship and leads to …
