Worker aggregation and baiting for management of subterranean termites
1994 - IRG/WP 94-10052
Environmental concern in the current use of cyclodiene and other chemicals for subterranean termite control had led to search of alternative environmental friendly management strategies. Worker aggregation and baiting are promising strategies. Aggregation is mediated through food recognition, attraction to some synthetic chemicals such as d-camphor, cinnamyl alcohol and sereral styryl compounds, semiochemicals released by wood decay fungi like Gloeophyllum trabeum, Poria monticola, Polyporus versicolor, Lentinus pallidus and present in the extract of leafsystem of Zizyphus jujuba. Effective bait toxicants include boron (TIM BOR), silafluofen, a sulfuramid, a dehaloalkyl arylsulfon, insect growth regulator, fenoxycarb, pathogenic fungi Beauvaria bassiana and Metarrhizium anisopliae, etc. Critical foraging behaviour for the success of this method and assessment parameters for determining the efficacy of aggregation and baiting systems have been discussed.
