Predation of Chilo suppressalis (Walker) eggs by the black cricket Metioche vittaticollis (Stal)


International Rice Research Notes 22(2): 43-44
Predation of Chilo suppressalis (Walker) eggs by the black cricket Metioche vittaticollis (Stal)
M. vittaticollis adult males and females and 4th-instar larvae were caged on 35-day-old plants of rice TN1 with freshly-laid egg masses of C. suppressalis glued to their leaves at densities of 80, 160, 240, 320 or 400 per plant. One individual, starved for 12 hours, was released on each plant. Fourth-instar larvae consumed the most eggs, feeding more than the first 3 instars combined. Females were more voracious than males, which was attributed to their physiological needs for reproduction.
