THE EXISTENCE SPESIES OF PASSIONFLOWER (Turnera subulata J.E SM. AND Turnera ulmifolia L.) ON PALM OIL PLANT (Elaeis guineensis J.) AGAINST TO THE DIVERSITY OF ENTOMOFAG AND PHYTOPHAGE INSECTS

Abstract

The research was purposed to inventory and identification types of entomofag and phytophage insects on Passionflower Plants in the area of PT. Tania Selatan part of Burnai Timur I . The area of research is ± 20 hectares, dominated by two species of Passionflower, there are Passionflower of Yellow Flower (Turnera subulata J.E SM.) and Passionflower of White Flower (Turnera ulmifolia L.). Entomofag and phytophage insects were collected using D-vaccum, and sweep net in every kind of Passionflower , started July until August 2017. The identification of entomofag and phytophage insects were done in the Laboratory of Postgraduate Sriwijaya University. The results of the study were 8 orders, 34 families and 48 species on T. subulata plants, and 9 orders, 26 families, 36 species on T. ulmifolia plants. The value of diversity index from entomofag and phytophage insects in T. subulata were 2.912 plant and the value of diversity index from entomofag and phytophage insects in T. ulmifolia plants were 2.603.

Hubungan antara asal bahan tanam dan jumlah ruas stek terhadap pertumbuhan bunga pukul delapan (Turnera subulata)

“…Terdapat 8 ordo, 34 famili dan 48 spesies pada tumbuhan T. subulata, dan 9 ordo, 26 famili, 36 spesies pada tumbuhan T. ulmifolia. Nilai indeks keanekaragaman serangga entomofag dan fitofag pada tumbuhan T. subulata sebesar 2,912 dan nilai indeks keanekaragaman serangga entomofag dan fitofag pada tumbuhan T. ulmifolia sebesar 2,603 [2]. Keberadaan tanaman Turnera subulata dapat dimanfaatkan untuk menekan perkembangan hama di perkebunan kelapa sawit dengan meningkatkan potensi musuh alami, baik predator ulat api seperti maupun parasitoid.…”
