Nelson M. Esguerra and Frank H. Haramoto ABSTRACT The potential importance of the western predatory mite, Galendromus occidentalis Nesbitt in the management of the carmine spider mite, Tetranychus cinnabarinus (Boisduval) was evaluated during a 1-year period on papaya trees at Kapaa, Kauai, Hawaii. One summer spray of Vendex at 0.56 kg Al/ha allowed some western …

Samuel I. Garcia and Manuel K. Palomar ABSTRACT The average number of leaf spots from natural infection was generally lower than that obtained when Yellow Dwarf coconut seedlings were artificially inoculated with spore suspensions of Pestalozzia palmarum Cooke. It was likewise observed that 200 to 300 spores per drop of inoculum produced the highest number …

Dely P. Gapasin and Lina Z. Rebadulla ABSTRACT The biology of the black leaf folder, Brachmia sp., and the green leaf folder, Psara hipponalis Walker, considered important defoliators of sweet potato, were studied in the laboratory. The total developmental period of the black leaf folder (20 days) is shorter than the green leaf folder (24 …

Franklin Chang, Nelson M. Esguerra and Eduardo A. Macion ABSTRACT Uptake of [1 –14C ] palmitic acid by the fat body of female adult Leucophaea maderae was measured in vitro. The fat body free fatty acid fraction showed the highest radioactivity., followed by triglyceride. The other lipid fractions showed low incorporation of label. The turnover …

Lydia A. Gloria ABSTRACT Poor quality of protein in copra meal diet was attributed more to poor digestibility than to poor nitrogen retention; in mungbean diet, it was due more to poor nitrogen retention than to poor digestibility. Nitrogen utilization of both diets decreased when protein levels were increased. The copra meal-fish meal mixture greatly …

Lydia A. Gloria ABSTRACT Biological and biochemical parameters were evaluated to assess protein quality. Some of the parameters are already well-established such as true digestibility, biological value and net protein utilization; others are still being used tentatively such as total urine nitrogen (NI), urine urea nitrogen (Nu), ratio of Nu to Nt (nu/Nt), onto urea, …
