If It Smells Like a Petunia or Shampoo, It Might Be a Pesticide

A smell that petunias and snapdragons recover to attract pollinators might be an environmentally accessible control for pests like a speckled wing drosophila fly (SWD) and a brownish-red marmorated scent bug.

Agricultural Research Service (ARS) chemist Aijun Zhang detected a perfumed chemical methyl benzoate, that is also a renouned part authorized by a U.S. Food and Drug Administration for use in foods, cosmetics and shampoo, can kill these insects and others.

ARS scientists found that a naturally occurring chemical, methyl benzoate, can kill brownish-red marmorated scent bugs

Few choices are accessible for determining SWD, that is an invasive class from Asia. It has fast widespread opposite a United States and can means poignant repairs to fruit crops, generally berries.

Zhang, who is with a ARS Invasive Insect Biocontrol and Behavior Laboratory in Beltsville, Maryland, points out a probability of a new bio-based pesticide—especially one formed on an inexpensive chemical whose excess lasts a comparatively brief time in a environment—is exciting.

Recently, Zhang was postulated a obvious for bomb use of methyl benzoate. ARS is seeking a association to permit a record and move blurb products to market.

Originally, Zhang was identifying flighty compounds in apple extract that captivated fruit flies. Compounds found in rotting apples and other fruits customarily attract flies. He found one compound—No. 19—strongly detered SWD, and after showed it killed them as well. Compound No. 19 incited out to be methyl benzoate, with a evil wintergreen-spicy, floral-fruity aroma.

Methyl benzoate valid to be 5 to 20 times some-more poisonous to eggs of brownish-red marmorated scent bug, diamondback arthropod and tobacco hornworm than a required pyrethroid insecticide, a sulfur and pyrethrin mixture, or some organic products now on a market.

Next, Zhang will exam methyl benzoate’s efficacy opposite mosquitoes, glow ants, hobo moths and stored-product insect pests. All of these insects are building insurgency to customary pesticides.

Zhang is also questioning either low doses of methyl benzoate could control Varroa mites, a No. 1 problem of managed sugar bees today.
