PENGARUH SUPERPARASITISME TERHADAP PERKEMBANGAN PROGENI PARASITOID Tetrastichus brontispae Ferriere
No full textThe purpose of this research was to investigate effects of superparasitism rate on development of Tetrastichus brontispae progeny. In this research, each host (Brontispa longissima pupa) was exposed for different frequencies, i.e., 1, 3, 5, 7 and 9 times for female parasitoid. The result showed that the rate of superparasitism affected the number of progeny emergence, the developmental time of immature progeny, and sex ratio of progeny. The number of progeny emergence was increased as the increase of superparasitism rate. The number of progeny emergence from single oviposition host was 15, while from host exposed on female parasitoid for 3, 5, 7, and 9 times were 12, 5, 2 and 0, respectively. The developmental time of immature progeny was lengthened as the increase of superparasitism rate. Sex ratio of progeny was biased to female progeny as the increase of rate of superparasitism. The result of this research indicated that superparasitism gave negative effect on development of T. brontispae progeny

No full textThis study was aimed at determining effects of soil surface treatments and organic matter types, as well as interactions between the two treatments on growth of cayenne pepper. The results showed that there were significant interactions between soil surface treatments and organic material types on plant growth of cayenne pepper at age of 5 weeks after planting. Surface treatments affected plant growth However, the soil surface treatments were influenced by types of organic matters given in the soil. On organic matter in the form of compost, the best growth was found on recycled newspaper mulch placed on soil surface. Conversely, on organic matter in the form of pieces of recycled newspaper, mulch of recycled newspapers gave the worst growth. Organic matters also affected plant growth. However, treatment of organic matter was also influenced by soil surface treatments. On the surface soil compaction treatment, the best growth was obtained at compost. On treatment of newspaper mulch, the best growth was also obtained at the type of compost. In contrast, on the untreated soil surface, the best growth was found at the type of organic matter made of the pieces of recycled newspaper
