Efficient Sex Pheromone Trapping: Catching The Sweetpotato Weevil, Cylas formicarius [PDF]

Journal of Chemical Ecology, 2012
The sweetpotato weevil, Cylas formicarius (Fabricius) (Coleoptera: Brentidae), is the most serious pest of sweetpotato around the world, damaging sweetpotatoes in the field and in storage, as well as being a quarantine pest. Because the larval period is spent within vines or tubers, and the adults are nocturnal, chemical control frequently is not ...

Segregation of hydroxycinnamic acid esters mediating sweetpotato weevil resistance in storage roots of sweetpotato [PDF]

, 2017
Resistance to sweetpotato weevils, (Cylas spp.) has been identified in several sweetpotato (Ipomoea batatas) landraces from East Africa and shown to be conferred by hydroxycinnamic acids that occur on the surface of storage roots.

Fungal volatile organic compounds show promise as potent molluscicides

Pest Management Science, Volume 75, Issue 12, Page 3392-3404, December 2019., 2019
Slugs and snails avoid plants treated with conidia and VOCs of the insect pathogenic fungus Metarhizium brunneum. The VOCs show promise as mollusc repellents or molluscicides. Abstract BACKGROUND Slugs and snails constitute major crop pests. Withdrawal of metaldehyde has prompted a search for more environmentally friendly yet fast acting molluscicides.
