Abstract

Potensi Cendawan Entomopatogen Beauveria Bassiana (Balsamo) Vuillemin untuk Mengendalikan Hama Boleng Cylas formicarius F. (Coleoptera: Curculionidae) pada tanaman ubijalar. Ubijalar merupakan salah satu tanaman umbi yang memiliki keunggulan sebagai alternatif penghasil karbohidrat. Hama boleng, Cylas formicarius, merupakan salah satu hama penting pada ubijalar yang dapat menurunkan kualitas dan kuantitas umbi antara 10–80%. Cendawan entomopatogen, Beauveria bassiana, berpotensi sebagai salah satu komponen pengendalian hama terpadu (PHT) yang dapat digunakan mengendalikan hama C. formicarius. Hasil beberapa penelitian menunjukkan bahwa cendawan B. bassiana dapat menyebabkan kematian pada C. formicarius hingga 90% dan efektif mengurangi kehilangan hasil sebesar 5%. Efektivitas cendawan entomopatogen B. bassiana dipengaruhi oleh kerapatan konidia, stadia serangga yang dikendalikan, waktu aplikasi, cara aplikasi serta frekuensi aplikasi. Oleh karena itu, pemanfaatan B. bassiana untuk mengendalikan C. formicarius dengan formulasi yang tepat sertadapat meningkatkan patogenisitas perlu dikaji lebih lanjut.

Abstract

Cylas formicarius (Fabricus) (Coleoptera: Curculionidae) is one of the major pest on sweetpotato which can cause yield lost up to 100%. The objective of this study was to obtain the effective and efficiency control technique of sweetpotato weevils. The research was conducted on June–October 2014 at Muneng Research Station, Probolinggo, East Java, using randomized block design, five treatments and three replicates. The treatments consisted of immersion of sweetpotato cuttings in the suspension of conidia Beauveria bassiana (Bals.) Vuill. for 30 minutes before planting; application of suspension of conidia B. bassiana on soil at 2, 4, 6, 8, 10, and 12 weeks after sowing (WAS); immersion of sweetpotato cuttings in the suspension of conidia B. bassiana for 30 minutes before planting combined with application of suspension of conidia B. bassiana on soil at 2, 4, 6, 8, 10, and 12 WAS; application of chemical insecticide every week; and control. Analysis of variance showed that the application of various control technique significantly lowered the population of larvae and imago of C. formicarius and the level of tuber damage. The population level found on all treatments ranged from 1–4 eggs/plant, 1–19 larvae/plant, 0–0.2 pupae/plant and 0–4 imago/plant. The weight of tuber was 571–700 g/plant with the level of damage 6–53%. Low level of damage was found in the aplication of suspension of conidia B. bassiana on soil at 2, 4, 6, 8, 10, and 12 WAS which were 6%. Application of suspension of conidia B. bassiana on soil at 2, 4, 6, 8, 10, and 12 WAS can suppress the population of C. formicarius on tuber and reduce the level of damage up to 48%.

Abstract

Pests are one of the main obstacles in improving mungbean production in Indonesia. Currently, conventional control by using synthetic pesticides is less successful because the population and damage due to the organism are still high. This study aims to evaluate the mungbean pest control technology by using biopesticide. The experiment was conducted using randomized block design, five treatments and five replicates. The treatments were P1: preventive of neem seed powder (NSP), entompothogenic virus which contain Spodoptera litura nuclear polyhedrosis virus (Virgra), and conidia of entomopathogenic fungi Beauveria bassiana (BeBas) application; P2: SBM, Virgra, and BeBas application based on economic threshold (ET); P3: application of synthetic pesticides based on schedule; P4: application of synthetic pesticides based on ET; and P5: without control. The results showed that the pests were armyworm (Spodoptera litura (Fabricius)), whitefly (Bemisia tabaci (Gennadius)), Empoasca sp., Megalurothrips usitatus (Bagnall), brown stink bug (Riptortus linearis (Fabricius)), green stink bug (Nezara viridula (Linnaeus)), and pod borer (Maruca testulalis (Geyer)). The application of NSP, Virgra, and BeBas, as preventive measures and the application of synthetic pesticides based on schedule effectively were suppressed pest population. In contrast, the application of biopesticides and synthetic pesticides based on ET did not suppress the development of major pests. The application of biopesticide based on ET are safe for the survival of natural enemies. Meanwhile, the application of synthetic pesticides can destroy existing natural enemies. Integrated management of NSP, Virgra, and BeBas, that are applied preventively are potential to be innovative technology for controlling the major mungbean pest to replace synthetic pesticides.

Abstract

Sweetpotato weevil Cylas formicarius Fabricius is major obstacle in increasing of sweet potato production in various countries. Tuber damage due to C. formicarius causes yield loss up to 80%. This study aims to examine the integration control of C. formicarius in entisol, each control combination was composed of various components. The control integration was composed of various components of synthetic insecticide, application of entomopathogenic fungus Beauveria bassiana, weeding, turning of the stems, heap up, and cover mounds using plastic mulch. The study used a randomized block design, each treatment was repeated five times. The research was conducted at Kendalpayak experimental station from May to September 2017. The result showed that P5 with B. bassiana application five times, addition of 3 t/ha organic fertilizer, cover mounds by plastic mulch was most effective in suppressing of C. formicarius in endemic entisol.  The tuber weight at control combination (P5) was reached 23 t/ha or 56% higher than control combination of farmer cultivation (P1) was only 10 t/ha. The entisol land with an alluvial structure cracks easily during in the dry season, so that adults to penetrate the base of tubers and lay their eggs. The results of this study indicate that control combination of P5 can be recommended as a innovation control technology of C. formicarius in endemic entisol.
