Abstract

Corn is the important food and crop for Indonesian. Recently, production of corn decreased because ofthe pest (Helicoverpa sp.). Until now, the control of Helicoverpa sp. depend on the using of chemicalelement. However, effect of synthetic chemical element usage was the appearance of secondary pest,the death of useful insect and the high accumulation of pesticide residue both in biotic and abioticagroecosystem. The residue of pesticide should effect on human health and environment balance.Furthermore, the control method using biological agents that have pathogenicity to host was done..One of biological agents is entomopathogenic nematodes. Entomopathogenic nematodes can kill it’shost at 24-72 hours, have wide host range such as Lepidoptera, Coleoptera, Diptera and Hymenopteraorder, and have no negatif effect on environment. The aim of the research is to find nematodes asbiological agents that effective against pest of corn (Helicoverpa sp.). The research was done inlaboratory of HPT UPN ”Veteran” Jawa Timur and HPT University of Jember. Methods of theresearch were : 1) Isolating entomopathogenic nematodes from many endemic area of Helicoverpaspp. In East Java; 2) Identificating Entomopatogenic Nematodes; 3) Screening IsolatesEntomopathogenic nematodes from East Java. The result indicated that there was anEntomopathogenic Nematodes Isolate from Tulungagung that has the highest pathogenicity (100%).

Abstract

Helicoverpa armigera merupakan hama utama tanaman tomat karena mampu menurunkan produksi tanaman. Pada umumnya petani menggunakan pestisida kimia sintetik untuk mengendalikan hama ini tetapi penggunaan yang kurang bijaksana akan mencemari lingkungan dan produk budidaya. Salah satu alternatif pengendalian hama yang memperhatikan keamanan lingkungan adalah dengan memanfaatkan agens hayati. Penelitian ini bertujuan untuk mengkaji potensi Bacillus thuringiensis, Beauveria bassiana dan Steinernema carpocapsae sebagai pengendali hayati hama penggerek buah tomat dalam upaya mempertahankan produktivitas tanaman tomat. Perlakuan berupa paket pengendalian hama terdiri atas : Bacillus thuringiensis dengan konsentrasi 2 gram/liter; Beauveria bassiana dengan konsentrasi 0,2 gram/liter (kerapatan spora 109); Steinernema carpocapsae dengan konsentrasi 1.000.000 IJs/liter; Insektisida (bahan aktif profenofos) dengan konsentrasi 2 gram/liter dan kontrol. Berdasar hasil penelitian dapat disimpulkan bahwa : (1) Agens hayati berupa bakteri Bacillus thuringiensis, jamur Beauveria bassiana dan nematoda Steinernema carpocapsae dapat dimanfaatkan sebagai pengendali penggerek buah tomat (H. armigera), (2) B. thuringiensis lebih mampu menekan populasi hama dan menekan kerusakan tanaman dibandingkan dengan agens hayati lain, (3) B. bassiana lebih cenderung spesifik inang sehingga lebih mampu untuk menekan populasi dan kerusakan buah yang disebabkan oleh H. armigera, (4) S. carpocapsae kurang mampu menurunkan intensitas kerusakan buah H. armigera karena perilaku H. armigera yang pasif dan masuk kedalam buah tomat memperkecil kemungkinan infeksi dan (5) Aplikasi pengendali hayati masih mampu mempertahankan jumlah buah yang sehat dan lebih menekan kerusakan buah tomat.

Abstract

One of the pests that attack the citrus plant is the scales of the citricola scales Coccus pseudomagnoliarium (Homoptera: Coccidae) which attack the branches and branches of the orange plant. This research aims to determine the level of pathogenicity of Aschersonia sp. in controlling C. pseudomagnoliarium pests in citrus plants. This research was conducted by knowing the level of pathogenicity of Aschersonia sp. in C. pseudomagnoliarium pests based on observations of C. pseudomagnoliarium nymph mortality variables, mycosis, mummification, and LC50 values (Lethal Concentration 50) and LT50 (Lethal Time 50). This research can provide information on the pathogenicity of Aschersonia sp. against C. pseudomagnoliarium in citrus plants. The highest percentage of mortality occurred at the treatment density of 109 spores/ml with a value of 77.50% and the lowest percentage of mortality occurred at the treatment density of 105 spores/ml with a value of 15.00%. LC values indicate that the spores density of 2.8 × 107 spores/ml has been able to kill 50% of the test insects, while to kill 90% of the test insects requires a density of 2.4 × 1010 spores/ml and to kill 95% of the test insects requires a density 1.6 × 1011 spores/ml. The LT50 calculation results show that the 1 × 109 spore density treatment has the smallest LT50 value of 3.11 days.

Abstract

Soybean pod damage caused by N. viridula reached 61.37% of the total pods and 61.67% of the total seeds attacked. Efforts were made, namely the application of chemical insecticides made from active chlorpyrifos which can reduce the population of N. viridula to reach 57.4% and the insecticides made from deltamerin which are reducing the population by 51.6%. Control is needed that can reduce the negative effects caused by chemical insecticides, one of which is mechanical control. Mechanical control can be done one of them with augmentation and conservation tools. the research is by taking the eggs of N. viridula in the field and laying the eggs in an augmentation and conservation tool with several treatments of different filter cloth diameters, 0.1 mm; 0.3 mm; 0.2 mm; and 0.6 mm. Observations were made by looking at and counting the number of parasitoids that were able to pass through the filter cloth and those that did not pass through the filter cloth, followed by identification of the species of the parasitoid that was obtained. The results showed that the parasitoids were able to escape in all treatments but with varying amounts. The difference in number can be influenced by the presence of parasitoids in the field and the level of parasitoid parasitation. Likewise with Trichogramma sp also able to pass on all treatments. Therefore, the most suitable treatment is treatment with a 0.1 mm diameter filter cloth. The identified parasites were T. rowani and T. podisi
