Abstract

NPV is one of the biological insecticides that kills the target by infecting their cells including hemocytes. Hemocytes play a key role on defence mechanism against pathogens like NPV. This defense mechanism may cause the insect to become more tolerant as well as to chemical insectisides. The tolerances of insect to NPV could be induced by cellular immune system (CIS). One of the CIS is capsules/nodules formation. Based on that assumption, this research was conducted to observe the alteration of capsules/nodules formation of Helicoverpa armigera larvae post sublethal infection of HaNPV (Helicoverpa armigera nuclear polyhedrosis viruses). The fifth instar Helicoverpa armigera ware infected by sublethal doses of HaNPV. 24 hour post infection, partly of survive larvae reared to get their first (NPV-F1) and second filial (NPV-F2). Another survivor induced by hit killed Bacillus cereus, and then its haemocoel were exposed under stereo microscope (total magnification, 60 X) to watch capsules/nodules that appear as black spots on haemolymph. This procedure also conducted to fifth instar larvae of NPV-F1, NPV-F2, control (K-P) and their filial (K-F1 and K-F2), blank and placebo. The result showed that the number of nodules/capsules on larvae were not significant between control and the NPV-treat larvae on every generation, which was about 4 nodules/capsules. It showed that there is no cellular immune respon changed on NPV-P larvae, so their immune ability are similar to larvae K-P. The recoveries of NPV-P larvae cause it have a good capability to produce offspring with good immune response. So, NPV-F1 and NPV-F2 larvae have same ability as K-F1 and K-F2 larvae. It can be concluded that the use of sublethal dosage of HaNPV has not changed formation of capsules/nodules of H. armigera larvae and their offspring.

Abstract

Abstract. Wadi is a sort of traditional foods that made of fish from Dayak tribe in Central Kalimantan. Wadi is made by the addition of salt and lumu. People make wadi as a supply of side dishes during difficult seasons of fish and stock for farming, hunting, or collecting forest products. In wadi, there are several bacteria species that capable in degrading amylum and protein. The bacteria capability in amylum and protein degradation can be determined by calculating the hydrolysis index. The aims of this study are to: (1) identify the amylolytic bacteria and proteolytic bacteria species from wadi, (2) determine the amylum and protein hydrolysis index on each amylolytic bacteria and proteolytic bacteria species isolated from wadi, and (3) determine the amylolytic bacteria and proteolytic bacteria species that have the highest hydrolysis index. This research is descriptive explorative research. The research results showed that: (1) there were four isolates of amylolytic bacteria isolated from wadi, i.e: Enterobacter agglomerans, Pseudomonas fluorescens, Acinetobacter baumannii, and Micrococcus varians, and there were five species of isolated proteolytic bacteria from wadi, i.e: Enterobacter agglomerans, Pseudomonas fluorescens, Nitrococcus mobilis, Acinetobacter baumannii, and Micrococcus varians, (2) the amylum hydrolysis index of Enterobacter agglomerans is 3.77; on Pseudomonas fluorescens is 3.00; on Acinetobacter baumannii is 4.16; and on Micrococcus varians is 7.23. The protein hydrolysis index of Enterobacter agglomerans is 3.22; on Pseudomonas fluorescens is 2.25; on Nitrococcus mobilis is 1.67; on Acinetobacter baumannii is 3.42; and on Micrococcus varians is 3.45, (3) Micrococcus varians has the highest amylum, i.e:  7.23 and protein hydrolysis index is 3.45.Keywords: hydrolysis index, amylolytic bacteria, proteolytic bacteria, wadi.
