The present disclosure discloses a method for inhibiting formation of a biofilm of bacteria. Specifically, the method may include treating the bacteria with an effective amount of a coumarin-chalcone compound. While inhibiting the formation of the biofilm of the bacteria, the effective amount of the coumarin-chalcone compound may reduce virulences of the bacteria and enhance a susceptibility of the bacteria to an antibiotic when applied in combination with the antibiotic. The present disclosure further discloses a composition including an effective amount of the coumarin-chalcone compound. The composition may be used to inhibit the formation of the biofilm of bacteria. The composition may also include an antibiotic, a minimal inhibitory concentration and a minimal biofilm eliminate concentration of which are reduced when the composition is used.

An object is to provide a chemical agent that, when used on carnivorous wasps such as those belonging to the Vespidae family, instantly stops them from behaving normally, to prevent injuries caused by stings and bites. As a solution, a carnivorous wasp control agent is provided, which is characterized in that it contains, as an active ingredient, at least one type of compound selected from the group that consists of (a) cyclic monoterpene-based compounds, (b) chain monoterpene-based aldehyde compounds, (c) chain sesquiterpene-based compounds, (d) benzoic acid alkyl esters, (e) lactic acid alkyl esters, (f) octanols, and (g) phenylacetic acid esters.
