Abstract

An entomogenous fungus, <i>Cordyceps militaris</i>, grows on larvae and pupae of the silkworm, <i>Bombyx mori</i>. To overcome problems in the establishment of fungal infection caused by advancing pupal-adult development, we tested the effects of carbon dioxide (CO<sub>2</sub>) anesthesia. Pupae inoculated with <i>C. militaris</i> were held in CO<sub>2</sub> anesthesia for 2 days. Almost all pupae exposed to CO<sub>2</sub> were infected with <i>C. militaris</i>, but the rate of infection of chilled or untreated pupae decreased with increasing stage of pupal-adult development at inoculation. The results indicate that exposure of silkworm pupae to CO<sub>2</sub> enhances infection rate. This treatment will support the mass production of <i>C. militaris</i> for pharmacological uses.<br>
