Development And Competition In Rice Weevil, Sitophilus Oryzae (L.) And Red Flour Beetle, Tribolium Castaneum (Herbst), And Their Responses To Active Compounds In Selected Spices.

Serangga hasil simpanan menyebabkan lebih daripada 20% jumlah kerosakan pada hasil simpanan di negara membangun dan lebih daripada 9% jumlah kerosakan di negara-negara maju setiap tahun. Keselamatan makanan adalah terancam terutamanya dengan peningkatan pesat dalam populasi dunia. Tesis ini bertu...
