DETECTION SURVEY OF KHAPRA BEETLE IN STORED AGRICULTURAL PRODUCTS IN CENTRAL JAVA = SUR VEl DETEKSI KUMBANG KHAPRA DI GUDANG PRODUK PERTANIAN DI JAWA TENGAH

Khapra beetle, Trogoderma granarium Evert (Celeoptera: Dennestidae) entered Central Java together with importation of stored products four decades ago. A survey was conducted to detect whether the Kaphra beetle existed in Central Java after they had been fumigated during commodity arrival. If the Kaphra beetle is absent, the data could be treated as the starting point toward declaring a pest free area (PFA) of Kaphra beetle in Central Java. The survey employed the procedure established in Australia, except this survey lasted for 11 months starting from April 2008 to February 2009. Insect traps (Trece Incorporation,Oklahoma, USA) were placed in eight sites distributed in six districts identified as high risk for Kaphra beetle. The traps were substitu\u27tedfollowing the label. The traps were checked every 2-4 weeks making the total observations varying from 18-24 times, except one site (eight times). No Kaphra beetle was observed during this detection survey. This finding strongly suggests that Kaphra beetle is not present in Central Java. Survey should be continued to collect data sufficient to declare PFAof Kaphra beetle. Kumbang Khapra. Trogodenna granarium Evert (CeleopteraDermestidae) masuk ke Jawa Tengah bersama sama dengan produk impor empat dekade lalu. Survei deteksi ini dilakukan untuk mendeteksi apakah kumbang Kaphra masih ada di Jawa Tengah setelah dilakukan fumigasi sejak kedatangannya. Jika kumbang Kaphra sudah tidak ada. data tersebut digunakan sebagai langkah awal pen etapan area bebas ham a (pest Free ArealPFA) kumbang Kaphra di Jawa Tengah. Survei menggunakan prosedur yang telah ditetapkan di Australia. yang dilakukan selama 11 bulan mulai April 2008 hingga Februari 2009. Perangkap serangga (produk dari Trece Incorporation, Oklahoma, USA) diletakkan di delapan tempat yang tersebar di enam Kabupatenlkota yang diidentifikasi sebagai daerah berisiko tinggi terhadap keberadaan kumbang Kaphra. Perangkap diganti dengan interval waktu dua bulan, dan diamati setiap 2 - 4 minggu. Jumlah observasi mencapai kisaran 18-24 kali, kecuali di satu gudang (delapan kali). Kumbang Kaphra tidak ditemukan selama survei deteksi berlangsung. Hasil ini menunjukkan bahwa kumbang Kaphra tidak ada di Jawa Tengah. Survei perlu dilanjutkan untuk memperoleh data samapai memenuhi untuk persyaratan penetapan PFA
