Abstract

Identification of Globodera rostochiensis was done based on the information given by the Direktorat Perlindungan Hortikultura, that the potato plants in the sub district of Bumiaji, Batu, East Java, were attacked by potato cyst nematode (Globodera). Plants and soil samples were taken from the potato's areas in the sub-district of Bumiaji, especially in the villages of Brakseng (± 1,700-1,800 m a.s.l), Tunggangan (± 1,600-1,700 m a.s.l), Kembangan (± 1,600-1.700 m a.s.l), and Junggo (± 1,200 m a.s.l). Based on morphological observations on eggs, larvae, females, and cysts, the nematode was identified as Globodera rostochiensis with special morphological characters: 1) second stage larvae vermifonn with total body length 531 - 563μ (x 548,4 μ), body width 22 - 26 μ (x 23,6u), stylet well developed with stylet knobs rounded, and part of the posterior portion hyaline in appearance; 2) cyst globular in shape with protruding neck, cyst's length 470 - 1,008 μ (x 638,08 μ), cyst's width 357 - 744 μ (x 490,33μ), and when the vulval basin is lost forming a single circular fenestra.

Abstract

In the past tea plantation at Pagilaran estate is attacked by leaf roller pests. These are Homona coffearia, Cydia leucostoma, and Gracilaria theifora. At present a slug Parmarion pupillaris is found and considered as a new leaf roller pest, because they live inside of the rolled leaf. This symptom is not known before. The population of Parmarion slug is high 3-4 slugs per bush of tea at the sub-division of Pagilaran estate of Pagilaran, Binorong and Garjito. This condition maybe supported by the weather that Pagilaran estate have a high rainfall of 4,842-6,067 mm per year with only 1-2 months of dry season.
