Abstract

The noxious pest termites are considered as a serious pest of both the human dwellings and forests throughout Pakistan. So, for their biological control, specimens of termite (Heterotermes indicola) both worker and soldier caste were collected from various localities of district Swat. Specimens were identified based on the morphometric characters of soldier caste. For biological control six different species of plants (Cannabis sativa, Teucrium royleanum, Solanum dulcamara, Lepidium penatifidum, Andrachne cordifolia, Zanthoxylum armatum) at concentrations 5000 ppm, 8000 ppm, and 10,000 ppm were investigated by using direct contact application and was used to determine their efficacy as termiticidal agent against H. indicola. Toxicity of various plant extracts was checked 72 hours after treatment. Cannabis sativa and Tencrium royaleanum were highly efficient against H.indicola and caused significant mortality. C. sativa at conc 5000 ppm, 8000 ppm, and 10,000 showed 4%, 12% and 68% mortality respectively at third day and T. royleanum at concentration 5000 ppm, 8000 ppm, and 10,000 showed 84%, 100%, 100% mortality respectively at third day of experiment. It was concluded that different dosages of T.royleanum can be used as an effective control agent followed by Cannabis sativa.
