“…The rice paddy in this period was still waterlogged and many small aquatic creatures were present, and the rice leaves had begun to grow, resulting in more pests that ate the rice leaves. The birds that entered the area mainly fed on insects and small aquatic animals [38]. The GP followed it.…”

“…Encouraging farmers to turn to organic farming can result in more excellent benefits for the ecosystem [44]. As for the inorganic rice paddy, the relationship between the number of insectivorous birds, and the number of insect pests had a moderate level of relevance [38]. In this area, chemicals were used in rice production, which decreased the number of pests in the area [45].…”

Birds play a vital role in rice cultivation as organisms that help maintain the ecological balance and help eliminate pests very effectively. However, various pests at each phase of rice growth, and the use of pesticides may cause differences in the bird species found in rice paddy. The objective of this research was to explore the species of birds found in organic rice paddy and inorganic rice paddy, and during each phase of rice growth, in Doi Kaew Subdistrict, Chom Thong District, Chiang Mai Province, Thailand. The bird data was collected between April and November 2018. Insects were also collected during each growth phase of rice to investigate the relationship with the number of birds found. There were 65 species found in the survey. Most of the birds were insectivores and belonged to Order Passeriformes. Birds found in the planted area were more similar to the organic rice paddy than the inorganic rice paddy. The values of Shannon Wienner's diversity index (H'), Simpson's index (λ), and Margalef's index (D) of the planted area were at the highest level, followed by the inorganic rice paddy and organic rice paddy, respectively. Birds discovered in both paddies were statistically different (p<0.05), and the bird found during each phase of rice growth were statistically different (p<0.05). Even so, the birds that presented in each habitat were more similar to each other than other habitat types. The correlation between insectivorous birds and insect pests was positive in both rice paddy types, indicating that if there were more insect pests, there would be more birds as well.

Ants are soil macrofauna that plays an essential role in preventing pods of cocoa (Theobroma cacao L.) from Helopeltis antonii and Conopomorpha cramerella attack. However, the method of those pests control primarily using pesticides and that will disturbed ant's life. This research aims to determine the abundance and diversity of ants in cocoa plantations with different shade and to determine the correlation between ant abundance and intensity of pest attack from Helopeltis antonii and Conopomorpha cramerella. Ants sample was carried out using pitfall traps and Berlese funnels based on purposive sampling method. The results showed that five subfamilies were found in cocoa plantations with different shade. Subfamily Myrmicinae was the dominant group in all observation sites. The ant abundance has a strong correlation with intensity of pest attack. This was influenced by a role of the ant as natural enemies from Helopeltis antonii and Conopomorpha cramerella.

Shade plants affect the microclimates around the plants which directly affect the population of arthropods, especially insects. Therefore, this research was needed to analyze the diversity and role composition of insects in Robusta coffee plantations based on different intensity of shade plants. Samplings of insects and parasitic nematodes were conducted in intercropping patterns of Robusta coffee namely mixed intercropping patterns, coffee-pepper intercropping patterns and coffee-banana intercropping patterns. In each intercropping pattern of Robusta coffee, samplings were conducted as much as ten plants using random sampling. Data analysis was done by calculating the Shannon-Wiener diversity index (H') and evenness index (E). The results showed that diversity index in all Robusta coffee intercropping patterns were < 3, indicating that the diversity of insects in all intercropping patterns was relatively. Insect diversity in coffee-pepper inter- cropping pattern is found higher than the one in either mixed intercropping pattern or coffee-banana intercropping patterns. Out of those intercropping patterns, insects from Formicidae family of Hymenoptera order was found to be the most dominant insects. The composition of insects in all of those three intercropping patterns has been mainly dominated by insects from the family of Formicidae and Hymenoptera order since they are natural enemy insects. Pratylenchus coffeaehas been confirmed as the most dominant nematode species in the three Robusta coffee intercropping pattern. P. coffeae had the highest population average of 3279 in coffee-pepper intercropping pattern.
