Intraguild interaction, attack patterns, and community structure of maize caterpillar in Bali province, Indonesia

Abstract Research on intraguild interaction, attack patterns, and community structure of maize caterpillar has been carried out in Bali province, Indonesia. The results showed that the population abundance index value was low (R1 = 1.08-1.91), while the diversity index value (H') was moderate with a value of 1.18-1.67, the similarity index value was in the very high category, namely IS = 100% , and the dominance index is moderate to low (D) with a value of 0.33-0.43. Found 3 guilds associated with maize in the field, namely stem-eating groups (Ostrinia furnacalis), leaf-eating groups (Spodoptera frugiperda, Mythimna separata, Spodoptera litura and Cnaphalocrocis medinalis), and cob-eating groups (Helicoverpa armigera). There is no competition between these caterpillars because each has a different profession. Caterpillar pest that attack corn plants are evenly distributed in all districts/cities in Bali Province with a random distribution pattern.
