Abstract

ABSTRAK Buncis (Phaseolus vulgaris Linnaeus) merupakan salah satu sayuran buah yang banyak dikonsumsi oleh masyarakat Indonesia. Produktivitas buncis di Provinsi Jambi tergolong rendah dibandingkan dengan produktivitas nasional. Salah satu hama yang menyerang tanaman buncis adalah penggerek polong (Etiella zinckenella Treitschke), sehingga perlu dilakukannya pengendalian. Pengendalian yang dilakukan petani adalah dengan insektisida sintetik, tetapi hal ini kurang efektif karena sifat larva yang menyerang di dalam polong. Selain itu, penggunaan insektisida sintetik dapat mencemari lingkungan dan berbahaya bagi konsumen, maka diperlukan alternatif lain seperti penggunaan varietas tahan. Penggunaan varietas tahan bertujuan untuk mengurangi populasi hama selama pertumbuhan tanaman dan untuk mengurangi persentase serangan penggerek polong. Tujuan penelitian ini yaitu untuk mengetahui tingkat serangan E. zinckenella pada beberapa Varietas Buncis tegak yaitu, Varietas Balitsa I, Varietas Balitsa III dan Gypsy. Penelitian ini dilakukan dengan membandingkan 3 perlakuan yaitu Varietas Balitsa I, Balitsa III dan Gypsy. Variabel pengamatan terdiri dari persentase polong terserang, populasi larva, kekerasan kulit polong, Padila et al., 2024 Preferensi Penggerek Polong 2 ketebalan kulit polong. Hasil penelitian menunjukkan bahwa E. zinckenella lebih menyerang buncis dengan kulit polong yang tipis dan kurang keras dikarenakan lebih rentan terhadap serangan hama dengan persentase polong terserang dan populasi larva yang lebih tinggi. Ketebalan dan kekerasan kulit polong berperan penting dalam ketahanan varietas buncis terhadap E. zinckenella. Kata kunci : bucis, E. zinckenella, ketahanan tanaman ABSTRACT Common bean (Phaseolus vulgaris Linnaeus) is one of the fruit vegetables widely consumed by Indonesian people. The productivity of common beans in Jambi Province is relatively low compared to national productivity. One of the pests that attack common bean plants is the pod borer (Etiella zinckenella Treitschke), which requires control. Farmers typically use synthetic insecticides for control, but this method is less effective due to the larvae's behavior of attacking inside the pods. Furthermore, the use of synthetic insecticides can pollute the environment and be harmful to consumers. Therefore, alternative solutions, such as using resistant varieties, are needed. The use of resistant varieties aims to reduce the pest population during plant growth and to decrease the percentage of pod borer attacks. The purpose of this study was to determine the level of E. zinckenella attack on several upright common bean varieties, namely Balitsa Variety I, Balitsa Variety III, and Gypsy. This research was conducted by comparing three treatments: Balitsa I, Balitsa III, and Gypsy varieties. The observation variables included the percentage of infested pods, larval population, pod skin hardness, and pod skin thickness. The results showed that E. zinckenella attacked more common beans with thin and less hard pod skins because they were more susceptible to pest attacks, resulting in a higher percentage of infested pods and larval population. Pod skin thickness and hardness play an important role in the resistance of common bean varieties to E. zinckenella. Keywords: common bean, E. zinckenella, plant resistance
