Comparison on the Capability of Four Predatory Mites to Prey on the Eggs of Bemisia tabaci (Hemiptera: Aleyrodidae)

On the leaf disc of fruit vegetables (cucumber, sweet pepper, tomato, egg plant, oriental melon), it has been evaluated that the capability of four predatory mites (Amblyseius swirskii Athias-Henriot, Neoseiulus barkeri (Hughes), N. cucumeris (Oudemans), N. californicus (McGregor)) to prey on the eggs of Bemisia tabaci (Gennadius) and to lay own eggs. The most aggressive mite was A. swirskii which had consumed about $9{\sim}12$ eggs in a day. The quantity of eggs consumed by N. barkeri, N. cucumeris and N. californicus was about $6{\sim}9,\;4{\sim}6$ and $1{\sim}4$, respectively. The most productive mite was also A. swirskii which had laid about $1.2{\sim}1.9$ eggs in a day. The others could not lay more than 0.5 eggs in a day.

포식성 이리응애 4종의 담배가루이 알 포식능력 비교 평가

시설과채류(오이, 착색단고추, 토마토, 가지, 참외)의 잎 절편에서 지중해이리응애, 나팔이리응애, 오이이리응애, 사막이리응애를 대상으로 담배가루이 알에 대한 포식능력과 산란능력을 비교 평가하였다. 지중해이리응애의 일평균 담배가루이 알 포식량이 $9{\sim}12$개로 가장 많았으며, 나팔이리응애, 오이이리응애, 사막이리응애가 각각 $6{\sim}9$개, $4{\sim}6$개, $1{\sim}4$개로 뒤를 이었다. 일평균 산란수도 지중해이리응애가 $1.2{\sim}1.9$개로 가장 많았으며, 다른 포식응애들은 0.5개를 넘지 않았다.
