Low level electrical energy (alternating and direct current), high voltage pulses from two energisers, and ultrasound were assessed for their ability to kill insects, or expel them from asparagus spears. Spears were held in an electrolyte solution containing 0.12 % (w/v) sodium chloride in water during the treatments. Electrical treatments lasted for 2, 4, or 8 minutes. A second experiment was used to test three chemical treatments applied for 8 minutes. None of the electrical and ultrasound treatments killed or expelled significantly more insects than the untreated controls in water or sodium chloride 0.12% (w/v). A new chemical, Y-14258, expelled and killed significantly more thrips than the other chemical treatments and control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
