Pengaruh Sex Rasio dan Jenis Pakan Terhadap Produksi dan Daya Tetas Telur Tiga Jenis Jangkrik Lokal Gryllus bimaculatus De Geer, Gryllus mitratus Burn dan Gryllus testaceus Walk (Orthoptera : Gryllidae)

Abstract

Study on the effect of sex ratio (1:1, 1:5, 1:), and two combination of feedstuff (feed meal + mustard leaves and feed meal + papaya leaves) on egg production and hatchability of 3 species of crickets (Gryllus bimaculatus De Geer, Gryllus mitratus Burn and Gryllus testaceus Walk). The results showed that Gryllus mitratus Burn produced higher number of eggs as compared to the two other species. Combination og feedstuffs had significant influence on egg production of which crickets given the combination of feed meal and mustard leaves produced more eggs than of papaya leaves with the highest hatcability. In regard with sex ratio, there was significant influence of the level of sex ratiuo of 1:5 at all species on egg hatcability but not egg production.
