| Summary: | Beneficial plants such as Turnera sp. serve as an ideal shelter and food source for insects, especially natural enemies, and this has attracted them to fields and helped in controlling insect pests. However, studies and information on the composition of insects visited and attracted to Turnera plants remain scarce, especially in Malaysia. Therefore, we identified insects attracted to Turnera trioniflora and compared the insect’s abundance and diversity between different times in paddy fields planted with T. trioniflora in Besut, Terengganu, Malaysia. We also evaluated the relationship between insects attracted to T. trioniflora and abiotic factors (i.e. temperature, rainfall, and relative humidity). Insects visiting T. trioniflora were collected using sweep nets and beating techniques at two different times (i.e. morning from 9:00 to 11:00 am and afternoon from 2:00 to 4:00 pm). The insects were collected once every two weeks during the paddy growing season (August-October 2023) and all samples were brought to the laboratory for identification process. A total of 177 insects individuals consisting of 17 species representing 10 families and six orders were successfully collected. It was found that 12 insect species were categorized as beneficial insects while five were insect pests. Libellulidae dominated the number of individuals collected with 32.20%, followed by Apidae (25.42%) and Formicidae (24.86%). T-test showed that the abundance of insects collected in the morning was significantly 64% higher than in the afternoon (36%). The diversity of insects in the morning was also significantly higher (H’=1.657) than in the afternoon time (H’=1.584). Abiotic factors have a significant correlation with the insects visiting T. trioniflora with rainfall alternated between positive and negative correlations, while relative humidity and temperature generally showed stronger positive correlations. In conclusion, the results show that T. trioniflora attracts more beneficial insects than insects pests of paddy, particularly in the morning, thereby helping the balance of the ecosystem in paddy fields. Therefore, this study can be the basic data for future studies of paddy pest management in Malaysia. |
