Abstract

Flubendiamide is a new insecticide that highly selective against Lepidopteran insect pests. A research was conducted to determine the effects of flubendiamide application on the mortality of nettle caterpillar S. asigna, bagworm M. plana, and bunch moth T. rufivena on mature oil palm. In addition, we also investigated the effects of flubendiamide application on the activity of pollinating weevil E. kamerunicus. Flubendiamide was sprayed directly on the affected oil palm canopy or fruit bunches at the application rate of 0, 50, 100, 150, and 200 mL/ha. On the other hand, flubendiamide was sprayed directly on the anthesis male inflorescences at the dose of 150 mL/ha to study for its impacts against the activity of E. kamerunicus. The results showed that the mortality of each pest increased in line with the dose of application. Flubendiamide was effective against the leaf-eating caterpillar at the application rate of 150-200 mL/ha whilst the application of 200 mL/ha flubendiamide was required for controlling the bunch moth. Moreover, the application of flubendiamide had no adverse effects on the activity and the development of E. kamerunicus on male inflorescences.

Abstract

Penelitian keanekaragaman serangga meliputi informasi jenis, nilai keanekaragaman dan kekayaan jenis serangga mulai banyak dilakukan berkaitan dengan penggunaan insektisida dalam mengendalikan hama di perkebunan kelapa sawit. Aplikasi insektisida jangka panjang selama 9 bulan dengan rotasi aplikasi dua minggu sekali telah dilakukan sebagai kajian informasi tentang penurunan jenis dan keanekaragaman serangga di perkebunan kelapa sawit. Jenis insektisida yang digunakan terdiri dari insektisida Fipronil, insektisida biologis Bacillus thuringiensis (Bt) dan kombinasi insektisida Klorantraniliprol (1 kali) dan Bt (3 kali). Penangkapan serangga digunakan perangkap nampan kuning, Malaise trapdan jaring serangga. Berdasarkan hasil pengamatan, serangga yang tertangkap pada seluruh lokasi pengamatan sejumlah 7.943 individu, yang terdiri dari 80 Famili dan 11 Ordo. Nilai indeks keanekaragaman dan jumlah individu pada lokasi dengan aplikasi insektisidakimia Fipronillebih rendah daripada perlakuan lain yang disebabkan berkurangnya jumlah famili dan individu, sedangkan pada lahan dengan aplikasi insektisida biologisBt maupun kombinasinya dengan insektisida kimia Klorantraniliprol relatif tidak mempengaruhi indeks keanekaragaman dan nilai sebaran serangga.

Abstract

The management of rat attack in oil palm plantation is commonly achieved through rodenticide application as well as in combination with the utilization of natural enemies. In this study, field efficacy of two rodenticide active ingredients i.e. coumatetralyl and Sarcocystis singaporensis against Rattus tiomanicus was conducted in mature oil palm blocks. The experiment was carried out in a randomized complete block design consisting of 3 treatments and 6 blocks/replicates. The application of coumatetralyl was conducted at the dose of 1 block bait per palm, while S. singaporensis treatment was conducted at the dose of 2 pellets per palm. The rodenticide application was carried out four times at five days interval. The result showed that incidence of rat attack decreased in all experimental blocks. The incidence of rat attack on coumatetralyl treatment was significantly lower than the control block at 5 and 10 days after application (daa), where as S. singaporensis treatment only showed a significant reduction at 5 daa. The average rate of reduction in rat attack during application of coumatetralyl, S. singaporensis, and control treatments was 53.80%; 38.58%; and 21.86%, respectively. The intensity of rat attack on male flowers before application was ranged between 31.87% to 40.64%, while the intensity on fruit bunches was ranged from 4.85% - 7.52%. The decrease in the incidence and intensity of rat attack is in line with the decrease in rodenticide consumption. In coumatetralyl treatment, consumed bait decreased from 75.02% to 57.03%, while in S. singaporensis treatment it decreased from 61.38% to 47.20%. In general, the efficacy value of coumatetralyl was higher than that of S. singaporensis.
