The abundance and diversity of the parasitoid of banana leaf skipper pest (Erionota thrax L.) in South Lampung Regency. This research was conducted to determine the abundance, diversity, and parasitation ability of several parasitoids of the banana skipper or banana leafroller (Erionota thrax) in South Lampung Regency. This research was carried out with a survey method by taking out samples of larvae and pupae of E. thrax in the District of Natar, Jati Agung, and Tanjung Bintang, South Lampung. Results of the survey showed that there were 8 types of parasitoids recovered from larvae or pupae of E. thrax, i.e. Brachymeria lasus (Chalcididae: Hymenoptera), B. thracis (Chalcididae: Hymenoptera), Charops sp. (Ichneumonidae: Hymenoptera), Casinaria sp. (Ichneumonidae: Hymenoptera), Xanthopimpla sp. (Ichneumonidae: Hymenoptera), Cotesia erionotae (Braconidae: Hymenoptera), and two parasitoids Diptera (Tachinidae and Sarcophagidae). The highest abundance of parasitoid was found in Tanjung Bintang with 171 parasitoids (index of diversity (H') = 1.0256 and index of evenness (E) = 0.5724). In Natar District, the abundance of parasitoid was 63 parasitoids, but it had a greater H' value (1.4396) and E-value (0.7398). Meanwhile, in Jati Agung District, the abundance of parasitoid was 56 individuals but the value of H' was also high, which was 1.012 with the value of E of 0.6064. The percentages of parasitation to the larvae and pupae E. thrax were 55.01% (Tanjung Bintang District), 31.68% (Natar District) and 33.34% (Jati Agung District).Key words: abundance, diversity, Erionota thrax, parasitoid
ABSTRAKKemelimpahan dan keragaman jenis parasitoid hama penggulung daun pisang (Erionota thrax L.) di Kabupaten Lampung Selatan. Penelitian ini dilakukan untuk mengetahui kemelimpahan, keragaman, dan daya parasitasi berbagai jenis parasitoid hama penggulung daun pisang Erionota thrax di Kabupaten Lampung Selatan. Penelitian dilakukan dengan metode survey, dengan pengambilan sampel larva atau pupa E. thrax sebanyak 60 sampel dari 3 desa dari setiap kecamatan (Kecamatan Natar, Jati Agung, dan Tanjung Bintang). Hasil penelitian menunjukkan terdapat 8 jenis parasitoid yang memarasit larva dan pupa E. thrax, yaitu Brachymeria lasus (Chalcididae: Hymenoptera), B. thracis (Chalcididae: Hymenoptera), Charops sp. (Ichneumonidae: Hymenoptera), Casinaria sp. (Ichneumonidae: Hymenoptera), Xanthopimpla sp. (Ichneumonidae: Hymenoptera), Cotesia erionotae (Braconidae: Hymenoptera), dan parasitoid dari ordo Diptera yaitu famili Tachinidae dan Sarcophagidae. Kemelimpahan parasitoid tertinggi ditemukan di Kecamatan Tanjung Bintang yaitu sebanyak 171 ekor parasitoid, dengan indeks keanekaragaman (H') sebesar 1,0256, dan indeks kemerataan (E) sebesar 0,5724. Di Kecamatan Natar kemelimpahan parasitoid lebih rendah yaitu terdapat 63 ekor parasitoid, namun nilai H' lebih tinggi yaitu 1,4396 dengan nilai E sebesar 0,7398. Sedangkan di Kecamatan Jati Agung, kemelimpahan parasitoid yaitu 56 ekor, dengan nilai H' sebesar 1,012, dan nilai E sebesar 0,6...
