The attack of Mimegralla coeruleifrons on ginger plants and its role in carrying pathogens of wilt diseaseRhizome flics Mimegralla coeruleifrons (Diplera; Micropezidae) ac frequently oten found in the diseased ginger rhizome caused by Ralstonia solanacearum, bill it has nol been known which one made the irst damage. Experiments were conducted at laboratory and green house of the Research Institute for Spice and Medicinal Cops from September 1998 to I'cbruary 2000. to examine the attack of M coerulefrons on healthy and disease ginger plants and its role in carrying the pauiogen. Hie experiments consisted of three parts, ink-station of the fly in healthy and diseased ginger plants, disease tansmission and detection of R solanacearum in M coeruleifrons larvae and adults, fiingcr plants were grown in pot containing, sterile media The pots were placed in the field and the plants were inoculated with R solanacearum and iininoculatcd. then they were caged or uncaged. Adult lies (33 - 35 pairs) were introduced into the cage. The uncaged plants were allowed to be naturally invested by the flies. Disease transmission used adult Hies which were collected from diseased ginger plantation. The lies were fed with suspension of R solanacearum. then introduced into cages containing healthy ginger plants. The flies were also directly caged on healthy plants Detection of/?, solanacearum in larvae and adults was carried out by isolation on selective medium and ELISA techniques. Results showed that M coerulefrons mostly attacked the inoculated ginger plants. Tliere was no evidence of Iransmission of R solanacearum by the fly. whereas nearly 50% of the ield collected lics carried R solanacearum. These results tend to suggest that the attack of M. coerulerons occured ater the ginger has been infected by wilt disease and the ly can be a carrier of/? solanacearum.

The cause of stunting disease of black pepper (Piper nigrum) in Indonesia has not yet been confirmed cither due o a virus or mycoplaam. However, similar disease found on black pepper plants in the Southeast Asia is caused by Piper yellow mottle virus (PYMV) which is transmitted by Planococcus citri. This expeiments was aimed o examine the cause of the stunting disease and its insect vectors. The expeiment were conducted from October 1998 to May 2001. Diseased vegetative materials of black pepper plants showing stunting disease were collected from Sukamulya, Sukabumi. The potential insect vectors were collected from black pepper plants in Bogor, IP Sukamulya (Sukabumi), Lampung and Bangka. The insects were fed on the diseased plants obtained from Lampung, Bogor and IP Sukamulya, then transferred o the healthy plants. The healthy plants were produced rom true seeds and cutings oiginated rom Bogor and IP Sukamulya. The tested plants were incubated at the green house and examined for disease development. Diseased leaf samples collected rom black pepper plant rom IP. Sukamulya and the transmitted plants were sent to the University of Minnesota, USA for Ihe virus (PYMV) by using ISEM (immunosorbent electron microscope). The result snowed that the leaves samples rom IP. Sukamulya were infected by PYMV. The morphology and size of the virus were similar to those caused stunting disease in the South East Asia. Potential insects vectors found on the diseased black pepper plants were two mealybugs, P. minor and Ferrisia virgata (Hemiptera; Coccoidca: PaaidbcoccidaeX aa well as an aphid Toxoptera aurantii (Hemiptera: Aphidoidea: Aphididae). The first tial on disease transmission by using P. minor, previously reared on the potato tubers, showed one out of ten tested plants produced disease sympom. The subsequent trial using P minor, bred on healthy black pepper seedlings, showed thee out often tested plants developed disease symptoms. None of the aphid transmitted plants developed Ihe disease. This study confirmed thai PYMV b the cause of stunting disease on black pepper in IP Sukamulya and Lampung and P. minor as the insect vecor of the disease.

Kubis, brokoli, dan bunga kol merupakan tanaman sayuran yang cukup penting, termasuk dalam famili Brassicaceae. Kendala utama dalam budidaya tanaman tersebut adalah serangan hama Crocidolomia pavonana. Minyak atsiri merupakan salah satu produk tanaman yang dapat digunakan sebagai alternatif pengendalian organisme pengganggu tumbuhan. Penelitian telah dilakukan di Rumah Kaca Kelompok Peneliti Proteksi Tanaman Balittro, sejak Maret sampai Desember 2014. Tujuan penelitian untuk mengetahui pengaruh minyak atsiri terhadap mortalitas telur, larva dan imago C. pavonana. Minyak atsiri yang diuji adalah minyak babadotan, cengkeh, laja gowah, seraidapur, seraiwangi, dan temulawak, masing-masing pada konsentrasi 0,5%. Selain itu, digunakan mimba sebagai pembanding. Pengujian ovisidal dilakukan dengan mencelupkan telur dalam masing-masing larutan uji. Untuk mengetahui pengaruhnya terhadap larva (larvasidal) telah dilakukan aplikasi bahan-bahan tersebut pada larva dan daun brokoli. Penelitian penghambatan peneluran dilakukan dengan menyemprotkan larutan ini pada tanaman, dikeringanginkan kemudian tanaman dikurung, dan serangga dewasa dimasukkan ke dalam kurungan. Pengamatan dilakukan terhadap penetasan telur dan mortalitas larva serta jumlah kelompok telur yang diletakkan. Hasil penelitian menunjukkan minyak seraidapur dan temulawak bersifat toksik terhadap telur. Minyak babadotan, mimba, dan seraiwangi yang diaplikasikan pada daun, mengakibatkan mortalitas larva lebih dari 90% tetapi, pada aplikasi langsung pada larva, mortalitas tertinggi berkisar antara 28% pada perlakuan mimba dan seraiwangi. Minyak babadotan, seraidapur, dan seraiwangi serta mimba memberikan pengaruh yang sama terhadap penghambatan peneluran pada 96 jam setelah aplikasi. Pengaruh terhadap peneluran juga terlihat pada perlakuan minyak temulawak yang telah diformulasikan. Minyak seraiwangi, seraidapur, babadotan, dan mimba serta temulawak berpotensi untuk digunakan sebagai insektisida nabati untuk mengendalikan C. pavonana.
