Beneficial plants such as Turnera can be a good shelter and provide a food source for insects. The presence of insects, especially natural enemies in paddy fields is very important because the insects help in natural pest population control. However, detailed studies on the composition of insects in paddy fields cultivated with Turnera plants are still lacking. Therefore, a study was conducted in Besut, Terengganu to determine the population abundance and diversity of insects in paddy fields cultivated with the beneficial plant, Turnera trioniflora. Two paddy fields were selected as sampling plots which cultivated with T. trioniflora plants (Plot A) and without T. trioniflora plants (Plot B). For each plot, three Malaise traps, five yellow pan traps, and five pitfall traps were used to collect insect samples on a weekly basis during the paddy planting season (February-May 2021). Samples collected were brought to the laboratory for identifying processes up to order level. Results showed that a total of 3818 individuals of insects consisting of 10 orders (i.e. Diptera, Hymenoptera, Lepidoptera, Coleoptera, Hemiptera, Orthoptera, Thysanoptera, Odonata, Mantodea, and Blattodea) were successfully collected from both plots with a significance different (p < 0.05). Among them, the Diptera dominated the number of individuals collected at 52.12% (n=1990) and followed by Hymenoptera at 16.87% (n= 644) and Lepidoptera at 12.40% (n=474). Whilst the Blattodea order was the least abundant with 0.07% (n=3). Plot A and Plot B recorded a total of 1995 and 1823 individuals, respectively and no significant difference (p > 0.05) of insect abundance was recorded between both plots. However, the diversity of insects in Plot A was slightly higher (H’=1.57) than in Plot B (H’=1.23). In conclusion, the insect’s abundance and diversity in a paddy plot cultivated with T. trioniflora plants was relatively higher than in a paddy plot cultivated without T. trioniflora plants. This study has provided a set of basic data on the abundance and diversity of insects in paddy fields which is very helpful for further studies on the relationship between T. trioniflora beneficial plants and insects.

Abstract

Beneficial plants such as Turnera can be a good shelter and provide a food source for insects. The presence of insects, especially natural enemies in paddy fields is very important because the insects help in natural pest population control. However, detailed studies on the composition of insects in paddy fields cultivated with Turnera plants are still lacking. Therefore, a study was conducted in Besut, Terengganu to determine the population abundance and diversity of insects in paddy fields cultivated with the beneficial plant, Turnera trioniflora. Two paddy fields were selected as sampling plots which cultivated with T. trioniflora plants (Plot A) and without T. trioniflora plants (Plot B). For each plot, three Malaise traps, five yellow pan traps, and five pitfall traps were used to collect insect samples on a weekly basis during the paddy planting season (February-May 2021). Samples collected were brought to the laboratory for identifying processes up to order level. Results showed that a total of 3818 individuals of insects consisting of 10 orders (i.e. Diptera, Hymenoptera, Lepidoptera, Coleoptera, Hemiptera, Orthoptera, Thysanoptera, Odonata, Mantodea, and Blattodea) were successfully collected from both plots with a significance different (p < 0.05). Among them, the Diptera dominated the number of individuals collected at 52.12% (n=1990) and followed by Hymenoptera at 16.87% (n= 644) and Lepidoptera at 12.40% (n=474). Whilst the Blattodea order was the least abundant with 0.07% (n=3). Plot A and Plot B recorded a total of 1995 and 1823 individuals, respectively and no significant difference (p > 0.05) of insect abundance was recorded between both plots. However, the diversity of insects in Plot A was slightly higher (H’=1.57) than in Plot B (H’=1.23). In conclusion, the insect’s abundance and diversity in a paddy plot cultivated with T. trioniflora plants was relatively higher than in a paddy plot cultivated without T. trioniflora plants. This study has provided a set of basic data on the abundance and diversity of insects in paddy fields which is very helpful for further studies on the relationship between T. trioniflora beneficial plants and insects.
