Abstract

Pseudomonas solanacearum is a bacterial agent causing wilt disease on mulberry species and other woody plant in Indonesian. Biological control employing the antagonist bacteria such as P. fluorescens and P. Putida is a potential method. The aim of the research was to know the effectiveness of P. fluorescens and P. putida to suppress wilt diseases caused by P. solanacearum. The diseases control test with antagonist bacteria was conducted by immersion of root of seedlings in P. fluorescens and P. putida suspensions before planted in a growth medium inoculated by P. solanacearum with the all concentrations were 108 CFU/ml. The following parameters were observed: numbers of leaves, fresh and dry weights of leaves and severity of disease. The results of the effectiveness test showed that antagonist bacteria in the form of mixing of P. fluorescens and P. putida was the best, because they were capable to suppress wilt disease caused by P. solanacearum and increased productivity of mulberry leaves. keywords : antagonist bacteria, biological control, wilt disease

Abstract

The purpose of this research to compared the biological aspect of silkworm seeds with two resources of seeds in South Sulawesi are Perum Perhutani (P1) and China hybrid (P2). The result of this research can be information for user of the sericulture. The observation will be done the hatchability of eggs, resistance of larva, and the characteristic of the larval. The observation of the cocoon quality such as whole fresh cocoon weight, the cocoon without pupa weight, the presentation of shell cocoon, the presentation of abnormal cocoon, and the characteristic of the cocoon. The data was analyzed with using proportion different test and t-student test. The result of this research was showed that hatchability of kind eggs as not significant. The resistance of larva as the higher from P2 and presentation of abnormal cocoon was lower. So the cocoon without pupa was not significant with the seeds from P1, but the cocoon weight and size of cocoon are bigger than from P2. Both larva motif and cocoon characteristic from P1 and from China hybrid is significant, but larva stadia from P2 was shorter than from P1. Key words : Biological aspect, silkworm (Bombyx mori), seeds resources References

Abstract

Fungi have a great diversity and wide distribution at the world. It can be used as the alternative technology for controlling of subterranean termite attack, particularly genus Coptotermes knowned as the wooden destructive organism, by using entomophatogenic fungi. For the purpose of the study, several isolate sources were taken from some locations. The results show that eight numbers of pathogenic fungi was founded by screening and identification of fungi taken from 19 numbers of isolate sources. The pathogenic fungi were Beauveria sp., Penicillium brevicompactum, P. rubrum, Paecilomyces fulvus, Fusarium verticolloides, Pythium sp., and Aspergillus sp. Key words: Jamur entomopatogen, Coptotermes sp.

Abstract

The purpose of this research to compared the characteristic and productivity of three silkworm seeds. The result of this research can be information for user of the sericulture. Three seeds examination from Perum Perhutani Soppeng ( P1), BS09 ( P2) and C103 ( P3) from Perum Perhutani Candiroto (Central Java).The observation will be done the hatchability of eggs, resistance of larval, and the characteristic of the larval. Result of research shows that stadium of P2 and P3 silkworm is shorter (21 days) than P1 (23 days). Larval characteristic; colored and larval pattern are equal relative except longer caterpillar P1 length from P2 and P3. Cocoon characteristic; colored, wrinkle and its hardness relative is of equal except size measure and form the cocoon, ellipse globular bigger P1 than P2 and P3 are elliptical like peanut. The result of this research was showed that examination three seeds hybrid of productivity observation (hatchability of eggs and resistance of mature larval,) P1 better than P2 and P3. Key words: Characteristic, productivity, hybrid seed, silkworm (Bombyx mori L).
