“…cv. Toyonoka (Kitagami and Ohkubo 1998), with about 22% of H. axyridis larvae remaining seven days after release. These decreased numbers could be a result of natural mortality, escape from the greenhouse, cannibalism (e.g., Dixon 2000), or predation by other predators, such as spiders (Kuroda and Miura 2003).…”

“…These parameters will provide a valuable reference for augmentative releases of H. axyridis as a biological control agent of M. sacchari in natural habitats. Releases of H axyridis eggs, larvae and adults have been studied (Tedders & Schaefer, 1994;Trouve et al, 1997;Ferran et al, 1998;Kitagami & Ohkubo, 1998;Kuroda & Miura, 2003). Growth stage of natural enemies needs to be considered as their searching rates and handling time vary with the developmental stages (Varley et al, 1973;Dixon, 2000).…”

“…There are three types of release methods for H. axyridis, egg masses, larvae and adults (Tedders and Schaefer, 1994;Trouve et al, 1997;Ferran et al, 1998;Kitagami and Ohkubo, 1998;Kuroda and Miura, 2003). The release stage of predators is an important factor that influences its effectiveness and potential economic benefits because the search rates and handling times of predators should vary with their development (Varley et al, 1973;Hassell, 1978;Dixon, 2000).…”
