Lady beetle diet influences its effectiveness as biocontrol agent
Date:1/11/2013

ugar sprays to soybeans and quantified the frequency of sugar feeding by analyzing the gut contents of common agronomic lady beetles in South Dakota, Maryland and Kentucky.

According to Seagraves, all the tested lady beetles regularly consumed sugarlike nectar in soybean fields, even when it wasn't applied as a supplement. However, the sugar-sprayed plots had more lady beetles than the untreated plots. This research makes the case that sugar-feeding is very important for lady beetle populations in cropland and suggests a possible way to help maintain beneficial species in agroecosystems.
