- Abstract
Rice (Oryza sativa L.) is one of the biggest commodities in Indonesia. Rice is cultivated in monoculture, so it affects the diversity of insects present in rice fields. The purpose of this research is to study the diversity of insect present at different ‘IR 64’ rice growth stages including seedling (21 DAP), vegetative (60 DAP), reproductive (92 DAP), ripening (115 DAP). The observation and sampling method was carried out by visual counting, using five repetitions at each rice growth stage. The specimen was identified using morphological characteristics. Total individuals of species obtained at each location were analyzed using diversity index and ANOVA. The correlation regression used to analyze the relationship between total of species and the developmental stage of rice. The results showed that at seedling, vegetative, reproductive, and ripening stages there were found 2, 11, 12, 7, and 12 insect families, respectively. The insect diversity index values at these stages were 0.96, 2.48, 1.81, and 2.28, respectively. Similarity index analysis showed that at vegetative and ripening stages tend to have high similarity. The correlation test results show the P-value of total individuals (N), total species (S), Shannon-Wiener diversity index (H’), and evenness index (E’) are 0.96, 0.732, 0.672, and -0.631. It means the number of individuals has a very strong correlation with the rice growth stage. The correlation between the total species and the diversity index with the age of rice indicate a moderate correlation. These results implied the more mature rice growth stage the more insect species diversity.
