Abstract

[THE ISOLATION OFSteinernema FROM CORN FIELD AND ITS PATHOGENECITY TO Spodoptera litura F]. Insect pathogenic nematode (IPN) offers an environmentally sound of controlling insect pest, as alternative for chemical insecticide. This research was conducted to evaluate the effectiveness of  Steinernema sp isolates collected from corn fields in Southern parts of  Bengkulu Province. The factorial experiment involved treatment combinations between sources of IPN isolate (Seluma, South Bengkulu, and Kaur) and density of IPN isolate  (100, 200, and 400 JI mL-1). The pathogenecity of the isolates were tested by inoculating the isolates on 4th instar of S. litura. The isolate of IPN collected from Seluma and Kaur corn fields were more effective in controlling the insect compared to those of the South Bengkulu as S. litura was killed faster and caused the 100 % mortality at 60 hours after inoculation. The symptoms of attacked larvae of S. litura were sluggish movement, body color changed to blackish with damaged internal organs. (JI=juvenile infective)

Abstract

[THE INCIDENCE OF POD-BORER, Maruca testulalis Geyer (Lepidoptera: Pyralidae) IN EIGHT MUNG BEAN VARIETIES (Vigna radiata L.) AND ITS EFFECT ON YIELD]. Mung beans are an essential food crop in Indonesia, whose production is still increasing to meet domestic needs. However, the high attack of plant pests Maruca testulalis Geyer (Lepidoptera: Pyralidae) is one of the leading causes of the low production of green beans. The use of superior varieties is one solution to controlling these pests. This study was conducted to test seven superior varieties of green beans, namely Vima 1, Vima 2, Vima 3, Murai, Kenari, Kutilang and Seriti and one local variety against M. testulalis. The study used a completely randomized block design and was repeated three times. The results showed that the mungbean varieties Vima 1, Vima 2, and Vima 3 had M. testulalis attack with the lowest level of seed damage in sequence, namely 5.84%, 7.94%, and 6.39%. Even though the percentage of pod borers attack did not significantly affect the growth of all Balitkabi superior varieties and one local variety of mungbean planted, the Kutilang variety was the highest yield with seed yield rates that were as low as other low-attack varieties.

Abstract

Melon (Cucumis melo L.) merupakan salah satu jenis tanaman semusim yang masuk ke dalam family Cucurbitaceae. Salah satu penyakit yang sering ditemukan menyerang tanaman melon adalah penyakit embun tepung. Serangan yang tinggi akibat penyakit ini akan mempengaruhi aktifitas fotosintesis dan pertumbuhan dari tanaman. Penelitian ini bertujuan untuk menguji pengaruh cendawan endofit hasil koleksi Laboratorium Proteksi Tanaman Universitas Bengkulu terhadap pertumbuhan tanaman melon yang terinfeksi penyakit embun tepung. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan faktor tunggal yang terdiri dari 5 perlakuan isolat cendawan endofit dan 1 kontrol. Cendawan endofit yang digunakan sebanyak adalah hasil seleksi patogenisitas pada penelitian sebelumnya. Aplikasi cendawan endofit pada tanaman dilakukan dengan menyiramkan suspensi endofit di sekitar perakaran tanaman sebanyak 10 ml per tanaman dengan kerapatan 106 spora/ml. Cendawan endofit diaplikasikan sebanyak 10 ml per tanaman dengan cara di semprotkan pada permukaan daun. Variabel yang diamati adalah tinggi tanaman, jumlah daun, tingkat kehijauan daun, suhu dan kelembaban sampai pengamatan 4 MSI. Hasil penelitian menunjukkan bahwa tidak terdapat perbedaan yang nyata pada respon pertumbuhan tanaman melon antara perlakuan. Namun saat tanaman berusia 4 MSI terjadi peningkatan pertumbuhan tinggi tanaman dan jumlah daun pada perlakuan C4 (Aspergilus sp.) yang lebih baik dari pada kontrol yaitu mencapai 115 cm dengan jumlah daun sebanyak 15 helai
UJI KONSENTRASI CENDAWAN Beauveria bassiana (Bals.) Vuill TERHADAP MORTALITAS KEPIK POLONG (Riptortus linearis) F. PADA TANAMAN KEDELAI Rika Aprilia Fajar Riningrum; Nadrawati Nadrawati; Edhie Turmudi

Abstract

[TESTING THE CONCENTRATION OF FUNGI Beauveria bassiana (Bals.) ON MORTALITY OF POD BORER (Riptortus linearis F.) ON SOYBEAN]. To control pod borer (Riptortus linearis F). on soybean using chemical insecticides can cause pollution to the environment, kill non-targeted insects and evolve pest resistance. The use of entomopathogenic fungus is an environmentally friendly alternative, one of which is Beauveria bassiana. (Bals.). The purpose of this study was to obtain an effective concentration of Beauveria bassiana fungi that can kill the pod borer at the 50% level.  The study was arranged in a Completely Randomized Design (CRD) consisting of 6 levels of fungi and 3 replications, where each experimental unit used 2 polybags.  Each treatment unit used 10 pod borers. The concentration of B. bassiana consisted of 105, 106, 107, 108 and 109 conidia / mL, and without fungi application as a control. The results indicated that the treatment of B. bassiana concentration on R. linearis significantly affected the percentage of mortality and the number of infected R. linearis, but no significant effect on the time of death, number of pods/plants and percentage of the number of damaged soybean pods. The mortality of R. linearis is classified as low, that is, less than 50%.
