The Effect of Hatching Media on Hatching Capacity and Stadium Nymph in Cricket Gryllus mitratus

Abstract

Cricket is one of potential animals that can be used as food souces, such as human food and feed of domestic animal because of its hight protein contain. Cricket can be produced by laying eggs after the process of fertilization. Cricket do not incubate it’s own eggs, but the incubation can take place in looses soil, sand, sock, cotton, and newspaper with the humidity of 70%-80%. The aim of this study was to know the effect of hatching media on hatchind capacity and stadium nymph I in cricket Gryllus mitratus. The study was conducted in a room of the Pandu house, Beringin Raya Village, Muara Bangkahulu Subdistrict, Bengkulu District from August until September, 2005. A number of the eggs of cricket Gryllus mitratus used in the study were 320 eggs with 4 replications of which each replication consisted of 20 eggs. Parameter measured were the first hatching body weight (mg), hatching ability (%), hatching weight (mg), hatching period (day), nymph period (day), the first nymp weight (mg), temperature and humidity of the chamber. The results showed that the hatchery of cricket eggs by using some haching media were significant different (P<0.05) on hatching ability and nymp I period. The average of hatching ability by the sand (70.00%) was not significantly different to that by the loose soil (73.75%) and combined treatments (71.25%), but it was significantly different (P<0.05) to that by the sock (86.25). The nymp I period by the sock was longer than the others. In conclution the sock was better to be used as hatching media of cricket eggs but it was not used for growing offspring of cricket.
