Abstract

Deli Serdang District is one of the regions producing red guava fruit in Sumatra Utara. Cultivation of fruit trees is never separated from pest disorders, which can cause a decrease in the quality and quantity of fruit. Then proper control is needed so that it can maintain the balance of insect populations in the field. This study aims to determine the type of parasitoid and parasitoid parasitic levels in red guava crops. Identification morphology of parasitoid?s fruit flies rearing from red guava fruit that had been attacked by fruit flies was taken from several locations of red guava crops in Deli Serdang District. Two species of parasitoid Psytalia sp. the parasitic fruit fly in the red guava crop.  The parasitoids that have been found then identified at LIPI, Cibinong, Bogor morphologically has many similarities with Psytalia walker and Psytalia walkeri so that identification of species is only made close to the morphology of the species. Only in two locations were found parasitoid?s rearing from infected fruit, namely Parasitization rate of 6.9% in Sei Beras Sekata village, and Kolam village of 3.6%.

Abstract

Hama kepik hijau (N. viridula L.) merupakan hama utama tanaman kedelai (Glycine max) serta dapat menurunkan produksi kedelai. Pengendalian hama ini dapat memanfaatkan insektisida nabati sebagai repellent menggunakan tanaman Tagetes erecta dipadukan dengan urine sapi. Penggunaan repellent umumnya tidak langsung mematikan serangga, namun lebih berfungsi untuk menolak kehadiran serangga, terutama disebabkan oleh baunya yang menyengat. Penelitian ini bertujuan untuk mendapatkan keanekaragaman serangga yang dapat berperan sebagai musuh alami dalam mengurangi serangan hama N.viridula pada tanaman kedelai. Penelitian ini menggunakan RAK Non Faktorial dengan lima ulangan. Perlakuan penelitian yaitu kombinasi pemberian serbuk Tagetes erecta dengan urine sapi dengan lima taraf yaitu kontrol (T0), Serbuk T.erecta 10 g+urine sapi 100 ml (T1), Serbuk T.erecta 15 g + urine sapi 100 ml (T2), serbuk T.erecta 20 g + urine sapi 100 ml (T4), serbuk T.erecta 25 g + urine sapi 100 ml (T5). Hasil penelitian mendapatkan lima spesies serangga yaitu E.admirabilis, Epilachna sp, M.sexmaculatus, V. linneata, I.sarcitorius yang digolongkan sebagai hama (1spesies), predator (3 spesies) dan parasitoid (1 spesies). Diharapkan dengan penelitian ini petani dapat memanfaatkan Tagetes erecta dan limbah urine sapi sebagai pestisida alami untuk pengendalian Hama Nezara viridula yang bersifat ramah lingkungan dan ekonomis.

Abstract

Armyworms (Spodoptera litura) become important pests in Indoensia that eat leaves compared to other pests because they are polyfag. S. litura can reduce productivity even crop failure. Therefore, it is necessary to do research on how to control S. litura effectively and environmentally friendly. This study aims to determine the effectiveness of brotowali extract (Tinospra crispa) as a botanical insecticide and obtain the right concentration of fruit extract, young leaves, and old Brotowali leaves to control the armyworm (litura Spodopter). This study used a Non Factorial Completely Randomized Design (RAL) with 6 treatments of various doses of brotowali extract mixed with cow urine and 4 replications. The results of the study showed that the administration of Brotowali + Urine Cattle extract with high doses (30 ml / jar) was able to increase the speed of death of the armyworm.
