Abstract

Sinanodonta woodiana is known as kijing taiwan which is mostly found in the irrigation flow of the village of Sambora Toho District Mempawah Distric. However, its existence is now experiencing a decline. For this reason, management is needed that requires data on morphometric and habitat characteristics. Therefore the purpose of this study was to determine the morphometric characteristics and habitat characteristics of S. woodiana in the irrigation flow of Sambora Village, Toho District, Mempawah Regency. The research method used was Purposive Random Sampling, using three different observation stations, namely station 1 is in the upstream part of the irrigation area close to a waterfall of oil palm plantations and freshwater fish cultivation ponds, station 2 is in an area adjacent to freshwater fish cultivation ponds and settlements, and station 3 is in a downstream area close to factory waste disposal tofu, freshwater fish farming ponds, and oil palm plantations.This research was conducted in March - May 2020 in the irrigation flow of Sambora Village, Toho District, Mempawah Regency. Based on the results of the study, there were 565 individuals of S. woodiana. All characters of mean shell length (PC), shell height (TC), shell thickness (TBL), and total weight (BT) show that the size varies between male and female sex, the female sex is greater than the male sex. The density values ranged from 0.37 to 3.02ind / m2. The density between stations is different and the highest is at station I and the lowest is at station III. Keywords: S. woodiana, Morphometric, Density.

Abstract

      Spodoptera litura (F) is one of the polyphagic pests. This study aims to determine the biological differences of S. litura (F) in artificial feed in the laboratory. The research was carried out in the laboratory of Plant Pest Faculty of Agriculture of Tanjungpura University from February - April. S. litura (F) is preserved in plastic cups (ice hood). The feed used was Phaseolus vulgaris L. and Vigna unguiculata L. The observations were made on 100 tails as individual cohorts per glass. The results of this study showed that Phaseolus vulgaris L. development period of S. litura (F) from hatching to imago ranged from 27 - 34 days, egg stage ranged from 3 - 9 days. The larvae consist of 5 instar, long instar stages I (2-3 days), instar II (4-6 days), instar III (2-4 days), instar IV (2 - 6 days), and instar V (1 - 4 days), pupa (5 - 12 days). The length of life of male imago ranges from 1 - 13 days and female imago 1 - 15 days. The post-spawning period ranges from 1 - 5 days. Fertility of eggs with an average of 84.08%. The number of eggs produced an average of 2,195.7 grains. In the feed Vigna unguiculata L. the developmental period of S. litura (F) from hatching to become imago ranged from 31 - 42 days, the stage of eggs ranged from 3 to 10 days. The larvae consist of 5 instar, long instar stages I (2-4 days), instar II (3 - 10 days), instar III (4 - 13 days), instar IV (3 - 11 days), and instar V (2 - 6 days), pupa (7 - 18 days). The length of life of the male imago ranges from 3 to 14 days and the female imago ranges from 2 - 17 days. Pre-breeding periods range from 3 - 9 days. The post-spawning period ranges from 1 to 6 days. Fertility of eggs an average of 77.06%. The number of eggs produced an average of 802.5 grains. Based on the average life cycle and the number of eggs produced then Phaseolus vulgaris L. can be recommended as feed for mass propagation.Keywords: Artificial Feed, Biology, Phaseolus vulgaris L., S. litura (F),   Vigna unguiculata L.
