Abstract

Oecophylla smaragdina or weaver ants is social insect that has an important role in the ecosystem. One of its main function is as a biological control agent in agriculture. The use of weaver ants in an effort to develop a biocontrol continues and increases, this has caused the significant decrease of the natural population of O. smaragdina. Therefore, the weaver ants rearing is needed to maintain its existence in natural habitat without excessive exploitation. The purpose of this study were to determine the effect of different types of feed i.e. snails, earthworms, and okara (tofu by-product) in the production of weaver ants kroto; and to determine the different of treatments of feeds provided to the production quantity of weaver ants kroto. The experimental method used in this study with a completely randomized design. Treatment was given by different protein sources feeding i.e. snails (Pomacea canaliculata), earthworm (Lumbricus rubellus), and okara. Five replicates were appliead for each treatment. Earthworms fed ants produced highest number of kroto with total of 1,030 individuals and weight 87.4 gram in total. Snails fed ants produced 866 individuals and weight 73.1 gram. Okara fed ants produced 543 individuals and weight 45.9 gram.

Abstract

Sweet potato (Ipomoea batatas L.) is one of alternative food sources beside than rice. Sweet potatoes are contains minerals, nutrients, sources of energy, protein, vitamins A and C. Sweet potatoes have lower productivity than rice and cassava. The low productivity of sweet potatoes due to several factors, which one of them is a leaf scab disease caused by pathogens Sphaceloma batatas Saw. The purpose of this study is to determine the character of the anatomy of sweet potato leaf cultivars that resistant and unresistant to the intensity of leaf scab disease, as well as the correlations between the anatomy character of sweet potato leaves with leaf scab disease intensity. The method used in this study is an experimental method with factorial completely randomized design. The first factor is the character of the anatomy of four cultivars sweet potato leaves, Cangkuang and Sukuh cultivars (cultivars resistant), cultivars Cilembu and Beta (unresistant cultivars). The second factor is the inoculation treatment S. batatas Saw. The parameters were observed thickness of cuticle, epidermis, mesophyll, the size (length and width) stomata, density of stomata and trikomata as well as the intensity of the disease were analyzed using analysis of variance (ANOVA). To determine the correlation between the anatomy character leaves with disease intensity using regression correlation analysis. The results showed that Cangkuang cultivar has cuticle, epidermis and mesophyll thickest. Beta cultivars have stomata size of the longest and widest. Cilembu cultivar has the highest density of stomata. Sukuh cultivars has the highest density. The anatomy characters include of a thick cuticle, epidermis, stomata size (length and width), as well as the density of stomata and trikomata correlated with intensity of leaf scab disease.
