Abstract

This study was conducted to determine the effects of crude extracts of betelnut, derris root, or wild heliotrope on the feeding response of two slug species, Filicaulis bleekeri and Parmarion pupillaris. Feeding test was performed in Petri dishes lined with wet white muslin by exposing 3 cm diameter leaf discs of treated -1 chinese cabbage with each extract (concentration of 50 g 100 ml water) to each slug species for 6 days. Control leaf discs were treated with water. Feeding response was measured by weighting leaf disc before and after 24 h feeding totaled into 6 days feeding period. Betel nut extract was further tested outdoor at the -1 concentration of 0 (control), 12.5, 25, and 50 g 100 ml . Filicaulis bleekeri (three slugs for each extract concentration) were released into each bucket and allowed to feed for 6 days. Percentages of leaf damage (consumed) by the slugs were measured at day 2, 4, and 6 after exposure. The results showed that crude extract of betelnut and derris root significantly reduced leaf feeding of F. blekeeri. The effect of betelnut extract was more pronounced than that of derris root. Wild heliotrope extract did not reduce slug feeding. Slug weight decreased in all treatments including control, but not on leaf treated with the heliotrope extract. There was no slug died from feeding on food treated with each extract. Theresponse of P. pupillaris was not conclusive. Betelnut extract reduced leaf damage by F. bleekeri significantly until day four after exposure.

Abstract

Laboratory Evaluation of Local Isolates of Beauveria bassiana and Metarhizium anisopliae against Coffee Berry Borer, Hyphotenemus hampei, using spryaing method. Beauveria bassiana Bals (Vuillemin) and Metarhizium anisopliae (Metschnikoff) Sorokin are two species of fungi that have been studied widely and used as biological control of various insect pests, including coffee berry borer (CBB), Hyphotenemus hampei Ferrari. Laboratory studies were done in June – July 2017, to evaluate local isolates of both fungi species against CBB, the most destructive insect pest of coffee worldwide, including in Indonesia. B. bassiana was isolated from dead sweet potato weevil (Cylas formicarius) and green stink bug (Nezara viridula), and from soil. M. anisopliae was isolated from soil. The pure cultures of the fungi were mass-cultured on corn based media. The conidia harvested from 4 week colonies was hand sprayed directly upon CBB adults (females) and damaged coffee berry at the concentration of 109 ml-1. In additions, the conidia of B. bassiana isolated from C. formicarius alone was diluted to 106- 109 ml-1 and applied to damaged coffee berry. The results showed that when the conidia were applied directly upon the insects, the mortality of beetle were higher in B. bassiana than in M. anisopliae treatments. Pooled data indicated that B. bassiana isolated from death insects significantly caused higher mortality than did M. anisopliae isolated from soil. Beetle mortality was 76.7 and 80.0% for B. basiana, and 60.3 and 60% for M. anysopliae treatments. Application upon damage coffee berry indicated much lower mortality. Application of higher concentration upon damaged coffee berry resulted higher mortality, but data are not consistent. The mortality of CBB larvae was much less and negligible even at the highest conidia concentration.

Abstract

Produktivitas lahan sawah beririgasi di Desa Sumber Agung, Bengkulu Utara masih rendah. Petani mempraktekkan budidaya padi secara konvensional dengan masukan pupuk dan pestisida kimia. Sekolah lapang pengelolaan hama terpadu (SLPHT) dilakukan untuk meningkatkan pengetahuan tentang ekosistem tanaman dan produktivitas padi sawah, dan mengurangi penggunaan pestisida kimia. Kegiatan dilakukan pada demplot seluas +7.500 m2, untuk membandingkan sistem pengelolaan hama terpadu (PHT) dengan sistem konvensional. Petani peserta SLPHT dilatih melakukan pengamatan ekosistem tanaman setiap minggu selama satu musim tanam (11 kali pertemuan). Hasil kegiatan menunjukkan adanya peningkatan pengetahuan petani tentang ekosistem padi dan pengelolaan tanaman sehat dan hama penyakit tanaman hampir dua kali lipat dengan skor nilai dari 42.72 menjadi 83.52. Aplikasi pestisida nabati dan agensia hayati dilakukan pada petak PHT sebanyak 3 kali,  sedangkan aplikasi pada petak konvensional sebanyak 8 kali dengan menggunakan pestisida kimia. Serangan dari hama burung pipit yang tidak bisa ditanggulangi menyebabkan produktivitas rendah. Hasil ubinan gabah kering panen (GKP) pada petak PHT adalah 2.3 + 0.36 kg (setara 2.172 ton per Ha) sedangkan pada petak konvensional 2.06 + 0.38 kg (setara 1.94 per Ha).
