Abstract

Beauveria bassiana is an entomopathogenic fungus that is widely produced for the benefit of biological control agents of various insect pests. The current production that is expected is to use cheap media but produce quality isolates. This study aims to determine colony growth, sporulation and viability of Beauveria bassiana conidia in several agricultural waste media. The experiment was compiled in a complete randomized design and replicated four times. B. bassiana in rice bran media added with cricket flour  had the fastest colony growth while B. bassiana in rice husk media was the lowest, lower than the control treatment. In  wheat bran media added cricket flour has slower colony growth than rice bran with cricket flour media similar to control treatment but has the second highest sporulation after rice bran with cricket flour media. The highest viability belongs to B. bassiana which is grown on rice bran with cricket flour media. The production in each treatment medium has a real effect but the addition of cricket flour has a significant influence in the production of quality isolates.

Abstract

Tomatoes (Solanum lycopersicum) are a horticultural commodity with high economic value and are widely cultivated in Indonesia. However, tomato productivity is often limited by pest and disease attacks. This study aims to identify insect species and analyze the intensity of diseases that attack tomato plants. The research methodology used was quantitative descriptive research involving two main components, namely identification in the laboratory and direct observation in the field. The research findings showed that there were four types of arthropods with various roles in the tomato ecosystem, namely Spiders (Lycosa sp.) classified as Natural Enemies; Ants (Odontoponera sp.) classified as Predators; Grasshoppers (Oxya chinensis) classified as Pests; Moths (Order lepidoptera) classified as Pests. In addition to pests, brown spot disease (Alternaria solani) was also found. The results of observations of the intensity of disease attacks showed differences in each treatment, the intensity of disease attacks was highest in the treatment without mulch and suckering compared to other treatments.
