Adults and nymphs of Podisus nigrispinus reared for three and four generations, respectively, on a meat-based artificial diet were able to find, capture and feed on velvetbean caterpillar ( Anticarsia gemmatalis Hüb. (Lep., Noctuidae)) in laboratory and in greenhouse. In laboratory, nymphs reared on artificial diet were more aggressive to their prey than those reared on house fly larvae ( Musca domestica L. (Dipt., Muscidae)), an alternative prey currently used for rearing this predatory species. Adults reared on the artificial diet behaved similarly to those reared on house fly larvae. In greenhouse, adults and nymphs of P. nigrispinus previously reared on artificial diet and released on soybean plants ( Glycine max (L.) Merr.) exhibited prey capture ability comparable to those reared on house fly larvae. Therefore, predators reared on this meat-based artificial diet seem to be as suitable for biological control programmes as those reared on house fly larvae. [ABSTRACT FROM AUTHOR] |
