Abstract

Spodoptera exigua is a migrant pest that attacks onions simultaneously in groups. The utilization of papaya leaves to control pests due to papaya leaves have toxic compounds that can kill pests. This study aims to measure the ability of papaya leaves to control S. exigua larvae. This research was conducted using a completely randomized design (CRD) experimental method with two treatment factors. The first factor was papaya leaf concentration (0 g / l, 30 g / l, 70 g / l, 100 g / l, 120 g / l), and the second factor is a mixture of kerosene. The treatment was repeated three times. The study was conducted at the Agrotechnology Laboratory, Agriculture Faculty Muhammadiyah University, South Tapanuli. The results showed that papaya leaves could kill S. exigua larvae. The highest mortality of S. exigua worms There were statistically significant non-treatments among treatments.

Abstract

Asiatic citrus psyllid Diaphorina citri Kuwayama has been considered as one of important citrus pests and a vector of a serious citrus disease as well, greening disease or known as Huanglongbing (HLB). Among entomophatogenic fungi which can be used to control those pest insects isBeauveria bassiana.The objective of this study was to measure the infectivity ofB. bassianaagainst adult of D. citri.B. bassianaconidia that used were 103, 104, 105, 106, 107, and 108conidia/ml.The experiment was repeated three times and arranged in a completely randomized design (CRD). Mean was analized by Duncan's multiple range test correction at the level α=0.05. B. bassianacaused mortality of D. citriat rate of 10%, 15%, 18.33%, 26.67%, 33.33% and 53.33% respectively. The result showed that LC50 of B. bassianawas 1.52 x 108conidia/ml.

Abstract

Pemanfaatan cendawan entomopatogen sebagai agens pengendali hayati merupakan salah satu cara untuk menghindari dampak negatif bahan kimia terhadap lingkungan. Cendawan entomopatogen yang telah banyak digunakan untuk pengendalian serangga hama secara hayati adalah Beauveria bassiana, Metarhizium anisopliae, Aspergillus sp., Nomuraea rileyi. Cendawan tersebut bersifat patogenik terhadap berbagai jenis serangga dengan kisaran inang yang luas. Cendawan entomopatogen lebih mudah didapatkan pada daerah rizosfer. Penelitian ini bertujuan untuk untuk mengetahui cendawan yang terdapat pada rizosfer berbagai tanaman hortikultura di beberapa wilayah Kabupaten Mandailing Natal. Cendawan entomopatogen diambil dari tanah di sekitar tanaman (rizosfer) hortikultura di 8 lokasi yaitu lahan pertanaman sawi, mentimun, kacang panjang, tomat, kedelai jagung, kacang hijau dan terung. Sampel tanah diambil pada lima titik dengan sistem diagonal. Isolasi cendawan dari tanah dilakukan dengan metode perangkap serangga (Insect baid method). Hasil penelitian menunjukkan dari seluruh tanah yang diteliti hanya ditemukan 1 genus cendawan entomopatogen dari rizosfer berbagai tanaman hortikultura di beberapa wilayah kabupaten Mandailing Natal yaitu Metarhizium.

Abstract

Entomopathogenic fungi are bioinsecticides used to control insect pests. Entomopathogenic fungi can found in the rhizosphere area of plants. This study aims to determine the germination, sporulation, and colonization of Metarhizium spp that are found in the various horticultural plants' rhizosphere of Padangsidimpuan. Metarhizium spp used were MetCP, MetKP, MetMP, MetKPP, MetSP, MetJP, MetTP. This research conducted in the Agrotechnology Laboratory of the Faculty of Agriculture, Universitas Muhmmadiyah Tapanuli Selatan. The study used a completely randomized design (CRD). The results showed that the highest germination rate at 6 hours after inoculation (HAI) founded in MetKPP of 31.05%. MetKPP also had the highest germination rate of 37.43% on 24 HAI. The highest diameter growth founded in MetKP, which was 5.50 cm at 14 HAI. The highest conidia density was 1,821 x 106 conidia/ml, found in MetMP, significantly different from MetCP, which had the lowest conidia density that was 1.169 x 106 conidia/ml.
