New banker plant paper!

Sarah Jandricic, a postdoc in the lab, just published a paper titled “The effect of banker plant species on the fitness of Aphidius colemani Viereck and its aphid host (Rhopalosiphum padi L.)” in Biological Control.

Effects of grain species on wasp abundance.

Effects of grain species on wasp abundance.

The paper describes the effects of different grain species on aphid and parasitoid wasp development and fitness. The goal was to identify which gain species would make the best banker plant for greenhouse growers. Each grain, barley, wheat, rye, and oats, had different effects on aphid and parasitoid development time, fecundity, abundance, and other measures. However, wheat and barley consistently produced parasitoids with high fitness and in great abundance. Importantly, cultivar within species had little effect so whatever cultivar grows best in your region should work.
