Ovipositional Behavior Of The 12-Spotted Lady Beetle, Coleomegilla Maculata: Choices Among Plant Species And Potential Factors Influencing Those Choices, Marisa Lynn Griffin Jan 2000

Ovipositional Behavior Of The 12-Spotted Lady Beetle, Coleomegilla Maculata: Choices Among Plant Species And Potential Factors Influencing Those Choices, Marisa Lynn Griffin

University of Kentucky Master's Theses

Coleomegilla maculata is a beneficial coccinellid commonly found in sweet cornfields in Kentucky. Previous work on C. maculata has shown an ovipositional preferencefor the weed Acalypha ostryaefolia, compared to three selected weed species and corn. Also, predation of C. maculata egg clusters on A. ostryaefolia was less compared toclusters on corn and the presence of A. ostryaefolia led to higher densities of C. maculata larvae on corn.

I determined C. maculata ovipositional preference among weed species in fieldtests using nine common weeds. I also examined ovipositional preference using just A.ostryaefolia and Abutilon theophrasti. I assessed the roles of …


Viral And Insect Genes That Inhibit The Immune System And Methods Of Use Thereof, Bruce A. Webb, Liwang Cui Oct 1998

Viral And Insect Genes That Inhibit The Immune System And Methods Of Use Thereof, Bruce A. Webb, Liwang Cui

Entomology Faculty Patents

Viral, endoparasitoid and/or host genes that specifically inhibit the immune response of insect pests, useful for broadening the host range of insect viruses. Symbiont viruses of insect pests are genetically modified to express immune-suppressing proteins or biologically active fragments thereof and, optionally toxins, to increase the virus host range and/or improve the efficacy of insect pathogens.


Automated Adjustable Interval Insect Trap, Yongbiao Liu, Kenneth F. Haynes Jul 1994

Automated Adjustable Interval Insect Trap, Yongbiao Liu, Kenneth F. Haynes

Entomology Faculty Patents

An automated, adjustable-interval insect trap includes a plurality of individual cards having a surface coated with insect adhesive to capture insects. The cards are received on trays having wheels that engage a series of four parallel guide rails. By operation of a positioning mechanism, the trays carrying the cards are moved along the guide rails, one at a time, into an insect capturing position for a selected time interval. The positioning mechanism includes a timer, a drive motor, an axle operatively connected to the drive motor and a series of spaced fan plates mounted on the axle at longitudinally spaced …
