Kepelbagaian dan Kelimpahan Serangga di Ekosistem Tanaman Cili

Diversity and Abundance of Insects in the Chilli Plant Ecosystem

Abstract

Kajian kepelbagaian serangga di ekosistem tanaman cili kurang dijalankan di Malaysia. Oleh itu, objektif kajian ini adalah untuk mengkaji kepelbagaian serangga dalam ekosistem tanaman cili berdasarkan peringkat penanaman cili yang berbeza. Kajian ini dijalankan pada Disember 2023 hingga Mei 2024 di Ladang Cili, Batu 14 Hulu Langat, Selangor menggunakan sepuluh perangkap lekit. Sebanyak 676 sampel serangga berjaya direkodkan (enam order dan 23 famili). Hymenoptera (348) merekodkan jumlah individu tertinggi. Formicidae adalah yang paling banyak (205 individu). Spesies paling banyak direkodkan ialah Paratrechina longicornis (205), diikuti Ephydridae sp.1 (174), dan Oceophylla smaradgina (60). Indeks Shannon-Weiner (H') menunjukkan nilai tertinggi semasa peringkat semai (H'=2.37) dan terendah selepas tuai (H'=1.865). Ujian ANOVA sehala tidak menunjukkan sebarang perbezaan yang signifikan dalam kepelbagaian spesies serangga antara peringkat sebelum semai, semai, tuai, dan selepas tuai (p > 0.05). Kajian lanjut mengenai interaksi spesies serangga di ekosistem tanaman cili diperlukan.

The study of the diversity of insects in the chilli plant is less conducted in Malaysia. Therefore, the objective of this study is to study the diversity of insects in the chili plant ecosystem based on different stages of chili cultivation. This study was conducted from December 2023 to May 2024 at Ladang Chili, Batu 14 Hulu Langat, Selangor using ten sticky traps. A total of 676 insect samples were successfully recorded (six orders and 23 families). Hymenoptera (348) recorded the highest number of individuals. Formicidae are the most numerous (205 individuals). The most recorded species is Paratrechina longicornis (205), followed by Ephydridae sp.1 (174), and Oceophylla smaradgina (60). The Shannon-Weiner index (H') shows the highest value during the seedling stage (H'=2.37) and the lowest after harvest (H'=1.865). A one-way ANOVA test did not show any significant differences in the diversity of insect species between pre-seedling, seedling, harvest, and post-harvest stages (p > 0.05). Further studies on the interaction of insect species in the chili plant ecosystem are needed.
