Image via Wikipedia There are two types of cockroaches large and small. With the rise in world wide travel, we are seeing new varieties of cockroaches formerly found only in Asia and the Middle East. The Larger Roaches: American Cockroach Smoky Brown Cockroach Oriental Cockroach Woods Cockroach The Smaller Roaches: German Cockroach Brown Banded […] BHT-induced lung damage by the cedarwood terpenes could not be overcomeeven when increasing the BHT dose up to 2500 mg/kg, or by delaying terpene administration until 2 hr after the mice had been injected with BHT. The resistance conferred by the terpenes was fully reversible within 4 days after removal of the terpenes from the mice. The lung weights in each of 13 different inbred strains of mice were increased by BHT, and this increase could be prevented by cedarwood terpene administration. The mechanism(s) by which the terpenes prevent BHT toxicity is/are unknown. The terpenes may act at the level of BHT metabolism, either by preventing activation of BHT to an active metabolite, or by accelerating BHT degradation, or both. Testing conducted with aerosol contact of five monoterpenoids on confused flour beetle (Tribolium confusum) One of the monoterpenoids, Terpinen-4-ol commonly found in the genus Juniperus (Cupressaceae) and is is widespread in the Northern hemisphere. The monoterpenoids tested revealed insect growth regulator (IGR)-like properties when applied to 3-day-old pupae, producing adultoids and deformed […] The antioxidant properties of wood extractives interfere with the termite and symbiotic microbial digestion. Over time, termites have learned to recognize and avoid wood with high levels of antioxidants. Consequently, termites will also avoid wood treated with artificial and nontoxic antioxidants. Juniperus oxycedrus was among thirteen essential oils tested in vapor form against Acanthoscelides obtectus (Coleoptera Bruchidae, Dry Bean Weevil) In choice and no-choice tests, most of of the essential oils tested had repellent action, reduce fecundity, decrease egg hatchability, increase neonate larval mortality and adversely influence offspring […] Monoterpenoids and sesquiterpenoids are the primary components of essential oils, which are highly volatile compounds that contribute to the fragrance (essence) of plants that produce them. Essential oils often function as insect toxins and many protect against fungal or bacterial attack. Improve the web with Nofollow Reciprocity. |
