“…The amount of feeding by M. vittaticollis in present finding was found two-three times more than consumption capacity of P. fuscipes, and Ophionea sp. However, this consumption rate was different than the result found by Rubia and Shepard (1987), that the cricket predator consumed lower number of brown planthopper nymphs of two to fourth instar nymph. DeKraker (1996) also found the low consumption of M. vittaticollis on brown planthopper nymphs, and this cricket preferred prey egg type rather than nymph or larvae.…”

Two generalist predators of brown planthopper,Metioche vittaticollis and Anaxipha longipennis (Gryllidae) have not been much studied in Indonesia. This research was conducted to study and compare the predatory ability of M. vittaticollis, A. longipennis (Gryllidae) and three coleopterans, Paederus fuscipes (Staphylinidae), Ophionea sp. (Carabidae),and Micraspis sp. (Coccinellidae) against brown planthopper (fourth and fifth instars) under laboratory condition. In total, 20 nymphs of N. lugens were exposed for 2 hour to each predator for 5 consecutive days. Prey consumptions by the predatory crickets, M. vittaticollis and A. longipennis were greater than the other predators and followed by A. longipennis, Micraspis sp., P. fuscipes, and Ophionea sp. respectively. Consumption rates of M. vittaticolis and A. longipenis were also higher than other predators. Micraspis sp was more active on predation in the morning,while M. vittaticollis, A. longipennis, P. fuscipes, and Ophionea sp. were more active both in the morning and the night but not in the afternoon. However, all five species of predators were not so active in preying during the afternoon. In conclusion, a major effort should be extended to conserve these predatory crickets especially M. vittaticollis and A. longipennis.

“…Previous studies on rice leaVolder egg predation by the crickets M. vittaticollis and A. longipennis were always conducted in single-plan t arenas in the laborator y (Bandong & Litsinger, 1986;Rubia & Shepard, 1987;Canapi et al, 1988;Rubia et al, 1990). This type of arena may be suitable for a ® rst comparison of predator or prey species (e.g.…”

The diet of both species includes a wide variety of small, slow-moving or immobile insect prey (Rothschild, 1970(Rothschild, , 1971Rubia & Shepard, 1987;Canapi et al, 1988). The crickets are reported as predators of rice pests in Thailand, Malaysia and the Philippines, both in lowland and upland environments (Tan, 1981;Yasumatsu et al, 1981;van Vreden & Ahmadzabidi , 1986;Litsinger et al, 1987;Barrion et al, 1991).…”

Cage experiments were conducted to quantify the predation rate of the cricket Metioche vittaticollis (Sta Ê l) on the eggs of rice leaVolder Marasmia patnalis Bradley. Egg predation by adult females was measured in response to changes in egg density, predator density and leaf area per cage. The number of eggs consumed per predator increased with egg density, without reaching a plateau. The predation rate decreased with increasing leaf area. The functional response could be adequately described with a linear Type I model, with the eVect of leaf area included. This type of response to leaVolder egg density means that predation was not limited by prey handlin g time or satiation, but by the search rate. The search rate is here interpreted as the leaf area eVectively searched for leaVolder eggs by a single predator in one day. Estimated search rates averaged 0.13 m 2 day 2 1 for M. vittaticolli s females. The search rate of the predators increased with prey density, but a model describing a density dependent search rate explained only 3% of the total variation in search rate. Increasing predator density per cage led to a decrease in the per capita egg predation rate when predator density was more than two per m 2 leaf area. Interference might thus reduce the potential to enhance leaVolder egg predation by conservation or augmentation of predatory cricket populations .

“…Soil insects will move to the rice crop and clean culture also may force termites to attack rice. Rubia (92) reported that among the weeds associated with the rice plant, M. vittaticolis preferred to oviposit on Fimbristylis miliacea (L.) Vahl and Monochoria vaginalis (Burm.f.) than clean ones.…”
