The Effects of Bora-care Alone and in Combination with Furfural Against Microcerotermes diversus Silvestri (Isoptera: Termitidae) in Laboratory Conditions

The use of wood preservatives is a suitable method to protect wooden products from termites attack. The effect of a Glycol Borate wood preservative and termiticide (available commercially as Bora-care) alone and in combination with Furfural were evaluated against M. diversus Silvestri (Isoptera: Termitidae). The major termite pest in Khouzestan province، Iran in choice and no-choice tests. It was found that mortality and repellency increased with increasing concentration of glycol borate and also with increasing Furfural concentrations. LC50 values in choice and no-choice trials increased for Furfural as time increased and their toxicities decreased proportionally، but LC50 values decreased for the Bora-care as time increased and their toxicities increased proportionally. LT50 values in choice and no-choice trials had an increasing trend as concentration decreased. In all tests، the glycol borate with Furfural prevented feeding and treated cellulose substrate damage. The results suggest that Bora-care alone and in combination with Furfural could be recommendable as wood preservatives against M. diversus.
