Abstract

Penelitian ini bertujuan untuk mengkaji pertumbuhan dan laju pertumbuhan Rhyzopertha dominica (Coleoptera: Bostrichidae) dan Oryzaephilus surinamensis (Coleoptera: Silvanidae) pada beras merah, putih, dan hitam, serta penurunan berat pakan setelah adanya infestasi hama tersebut. Penelitian dilakukan pada bulan Maret hingga September 2022 di Laboratorium Hama Tumbuhan, Departemen Hama dan Penyakit Tumbuhan, Fakultas Pertanian, Universitas Brawijaya. Penelitian ini terdiri dari dua faktor yaitu (1) spesies serangga hama (R. dominica, O. surinamensis, dan asosiasi) dan (2) jenis pakan (beras merah, putih, dan hitam). Sehingga, penelitian ini memiliki sembilan kombinasi dan diulang sebanyak tiga kali menggunakan Rancangan Acak Lengkap (RAL). Populasi imago baru R. dominica dan O. surinamensis diamati pada infestasi tunggal maupun asosiasi, serta penurunan berat pakan pada beras merah, putih, dan hitam. Data dianalisis menggunakan perangkat lunak R statistic versi 4.2.0. Hasil penelitian menunjukkan bahwa tidak terdapat interaksi antara spesies hama dan jenis pakan terhadap pertumbuhan populasi dan laju pertumbuhan populasi R. dominica dan O. surinamensis, serta penurunan berat pakan. Pertumbuhan populasi dan laju pertumbuhan populasi R. dominica dengan infestasi tunggal pada beras merah lebih tinggi dibandingkan dengan beras putih dan hitam. Pertumbuhan populasi dan laju pertumbuhan populasi O. surinamensis pada beras hitam lebih tinggi dibandingkan dengan beras merah dan putih. Penurunan berat pakan pada beras merah lebih tinggi dibandingkan beras putih dan hitam pada infestasi tunggal maupun asosiasi.

Abstract

The almond moth Cadra cautella (Walker) is a notable stored product pest which can cause detrimental loss on stored cocoa. Cocoa can be stored in bean and powder forms. The information about survival and development of C. cautella on stored cocoa is limited. This research aimed to determine the effect of cocoa powder and cocoa bean in the storage against the survival and development of C. cautella. This research was conducted in Plant Pests Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Brawijaya. This research consisted of two treatments namely cocoa bean and cocoa powder with no choice method and repeated six times. The observed variables were number of larvae, pupae, male and female almond moth of F1 progeny, and developmental time of this insect. The t-test analysis was applied to determine the treatment effect. Results showed that the number of larvae, pupae, adult males and females of F1 progeny cultured on cocoa powder were significantly higher than on cocoa bean. The total developmental time and life cycle of almond moth were shorter on cocoa powder than on cocoa bean. Therefore, to store cocoa in powder form is riskier to the almond moth infestation rather than in bean form. Hence, it is suggested to take more concern on the cocoa powder storage better in order to minimize the almond moth infestation.
