Abstract

Color preferences on post-harvest adult pests are useful for monitoring instrument development which based on the colonization and oviposition behavior. The research was aimed to determine the most attractive color with a certain wavelength for the test insects. The research was conducted in laboratory conditions of Plant Pest Laboratory, Department of Plant Pest and Disease, Faculty of Agriculture, University of Brawijaya at 27 ± 2°C, RH 65 ± 5%; and day:light 12:12 hours. Study of color preferences on six species of weevil used free choice test method and set by CRD with four replications using eight colors: white, red, orange, yellow, green, blue, indigo, and purple. The observed parameters were the number of adults and eggs laid. Results showed that each post-harvest insect had a different preference for various colors in the range of 380–450 nm wavelength. Adults of Sitophilus oryzae, Oryzaephilus surinamensis, O.s Mercator, and Tribolium castaneum were more preferred to feed and lay eggs in blue color (451–495 nm), Lasioderma serricorne was more preferred in indigo color (445–450 nm), and S. zeamais was more preferred in purple color (380–444 nm). The oviposition preference revealed that there was a positive correlation between the number of females and the egg laid.

Abstract

The red flour beetle, Tribolium castaneum (Herbts) is a major pest of flour from various grains. The infested flour is discoloured and will emit a disagreeable odour due to the secretion of benzoquinone from the insect’s abdominal glands. Considering the economic losses effected by T. castaneum, new alternative control measures are needed for this pest. This study sought to determine the host preferences of T. castaneum from amongst six kinds of flour to assess their vulnerability to infestation. The research was conducted in the Plant Pest Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, University of Brawijaya. The host preferences of T. castaneum were examined using a six-arm olfactometer. Feeding preference tests were performed for a duration of 12 hours at 200 ml/minute airflow in each chamber-arm, followed by oviposition preference observations one week later. Feeding preference was calculated for the total pool of adults observed, segregated by sex, whereas oviposition preference was calculated as the number of eggs laid. Flour nutrition (proximate composition, phenolic content, and riboflavin content) were analyzed. Our results showed a feeding preference by T. castaneum for bran, soy and tapioca flour was greater over wheat, corn, and white gelatinous rice flour, while for oviposition, bran flour was the most preferred.

Abstract

Jagung merupakan tanaman sumber karbohidrat sehingga mempunyai nilai strategis dan nilai ekonomis yang tinggi, akan tetapi praktik budidaya tanaman jagung mengalami berbagai kendala, salah satunya adalah keberadaan gulma pada lahan budidaya yang berpotensi menurunkan produksi tanaman jagung. Upaya pengendalian gulma oleh petani saat ini kurang efektif dan efisien karena kurangnya pemahaman tentang vegetasi gulma yang tumbuh. Penelitian ini bertujuan untuk menganalisis vegetasi gulma dan menentukan gulma dominan pada lahan budidaya jagung di Kelurahan Arcawinangun, Kecamatan Purwokerto Timur, Kabupaten Banyumas. Penelitian ini menggunakan metode kualitatif dengan mengidentifikasi gulma yang ditemukan, dan metode kuantitatif dengan menghitung dan menganalisis vegetasi gulma yang dominan. Pengambilan sampel dilakukan dengan metode Kuadrat menggunakan plot ukuran 0,5 x 0,5 m2 secara acak dengan melemparkan plot ke lahan budidaya jagung sebanyak 10 kali sehingga terdapat 10 plot sampel. Hasil penelitian menunjukkan bahwa terdapat 11 spesies gulma yang tumbuh pada lahan budidaya jagung di Kelurahan Arcawinangun, Kecamatan Purwokerto Timur dengan komposisi 6 termasuk golongan gulma berdaun lebar, 3 termasuk golongan gulma rerumputan, dan 2 termasuk golongan gulma teki. Gulma yang mendominasi pada lahan tersebut adalah Synedrella nodiflora dari golongan gulma berdaun lebar dengan nilai SDR sebesar 31,1%, dan Cyperus iria dari golongan teki dengan nilai SDR sebesar 23,8%.
