Abstract: Nitrogen containing compounds are effective as subterranean termite feeding stimulants/aggregants and as masking agents for concealing the presence of other compounds which are repellents to termites, when they are used in low concentrations, less than or equal to about 1000 ppm (0.1%, by weight). The nitrogen containing compounds may be formulated alone, or optionally in a bait or in combination with other compounds effective for controlling or marking subterranean termites.

Abstract: An improved artificial diet or growth medium for rearing the insect parasitoid Catolaccus grandis is disclosed. The growth medium is composed of amino acid, mineral, vitamin, lipid, and carbohydrate fractions which are present in amounts and proportions effective to support growth of Catolaccus grandis, and the amino acid fraction includes alanine, glutamic acid, histidine and proline at concentrations of about 3.0-5.0%, 8.4-9.4%, 10.0-15.1% and 11.7-12.8%, by weight, respectively. The growth medium is suitable for mass propagation of C. grandis from egg to adult for their subsequent release as biocontrol agents. Alternatively, the growth medium may be used to support growth of adult female wasps of C. grandis for use as breeding stock for continued mass propagation.
