Farmers' Perception of the Role of Some Wild Plants for the Predatory Coccinellidae (Adalia Bipunctata L and Coccinella Septempunctata L) in Developing Refugia in the Agricultural Field

摘要

The decreases in plant and animal diversity in intensive agricultural practice have been caused by the application of new and very broad-spectrum pesticides. This situation motivated some researchers to observe the attractiveness of wild plants for some predatory Coccinellids. This was done with a view to improving the agricultural ecosystem. Previous research results showed that Blumea sp. (L), Tagetes erecta L. and Bidens pilosa L. could attract predatory Coccinellidae: Adalia bipunctata L. and Coccinella septempunctata L. But, unfortunately, there were no research results showing how farmers accepted those related new improved strategies for controlling pests. The research was conducted to analyze what they felt about introducing the function of wild plants for attracting beneficial arthropods. To this end, 60 farmers were selected purposively as respondents in the south of Malang and interviewed in depth with the main question focusing on their knowledge of the general function of wild plants in agriculture. Then, more specifically, they were asked about the role of wild plants in the agricultural field for attracting these beneficial arthropods. Their answers were grouped into the following categories: they don't know, they know a little, they know enough, they know a lot about the general function of wild plants in general and more specifically as attractants for some beneficial arthropods. The results showed that the majority of farmers know only a little about the function of wild plants in general. None of the farmers realized that wild plants can be used as ground-covering plants. Most of them knew only about the use of wild plants for cattle feed. The majority of them did not know that some of the wild plants that can be found in their agricultural fields can be used as attractants in looking for beneficial arthropods. Farmers, as the frontier in the agricultural field, must become knowledgeable about the specific use of the wild plants in their fields to
