Capsule-C: an improved Steinernema carpocapsae capsule formulation for controlling Agrotis ipsilon Hufnagel (Lepidoptera: Noctuidae)

Abstract

Highlights We developed an improved capsule formulation named as Capsule-C supplemented with glucose, which can obviously increase the larva feeding amount of Agrotis ipsilon. The nematodes of Steinernema carpocapsae HB310 in Capsule-C survived well and maintained high pathogenicity against Galleria mellonella after storage for 180 days. Under laboratory conditions, Capsule-C could be released into the rhizosphere directly and effectively reduced maize seedlings damage by A.ipsilon.
