Contender) as Affected by the Application of Different Organic Amendments Tiw-an, Florinda The study was conducted at the University Experiment Station in a La Trinidad loam soil at Benguet State University, La Trinidad, Benguet, from December 2015 to May 2016. The soil and plant tissue analyses were done at the Laboratory of the Department of Soil Science of the College of Agriculture. The study aimed to determine the effect of the different organic amendments on the biological nitrogen fixation in bush beans, growth and yield in bush beans and on the nitrogen content of the soil. At flowering stage, plant height of bush bean was significantly affected by the application of the different organic amendments while the fresh weight, dry matter yield, plant tissue N and N-uptake were not significantly affected; likewise, root nodulation was not significantly affected. At harvest, the height, fresh weight, dry matter yield, plant tissue N, root nodulation and pod yield were not significantly affected by the application of the different organic amendments; however, N-uptake was significantly affected with calliandra giving the highest value of 584.41 mg/ plant.

Sixty soil samples were collected from four collection areas: inside living quarters, pathways, playgrounds and backyards. The samples were processed and analyzed by sodium nitrate floatation method and identified based on their morphological characteristics. The prevalence of STHs in Alno was 66.67%. The prevalences of STH among the four collection areas were not statistically different. Of all the STHs identified, hookworm had the highest prevalence (56.67%) followed by Toxocara spp. (38.33%). Hymenolepis spp. (3.33%), Ascaris spp. (1.67%) and Trichuris spp. (1.67%) were also identified but at lower prevalences.

A total of 119 respondents were interviewed. The demographic profile of the respondents revealed that most of them are married (90%) belonging to the age bracket of 41 to 60 years of age (54%). Most (36%) are secondary and tertiary graduates and (39%) of them are engaged in raising swine from 2 years to 5 years. Majority (90%) raise swine to gain income. Ninety –two percent of the total pigs raised are mixed breed and fifty-four percent are piglets. Majority (97%) of the respondents confined their pigs in an open shaded housing and very few (2% and 1%) had their pig roamed around the backyard and tethered respectively. Seventy-seven percent of the respondents consult a veterinarian or an animal technician when they observed problems concerning their animals. Most (71%) of the respondents also deworm their pigs as needed and nearly half (48%) of them do not have vaccination program. Sixty-six percent of the respondents practice wet feeding and 79% had their pigs fed twice a day with combination of commercial feeds and food waste. Majority (95%) of the raisers are using feeding trough. Cleaning of pigpen is done once a day by most (58%) of the swine raisers. Disinfection of the pig house is practiced by (10%) of the respondents. Mostly (61%), the waste products are flushed into an open drainage and some (21%) use it as fertilizer.

The study was conducted in Benguet State University, La Trinidad, Benguet from January to May 2016 to identify the different families of Lepidoptera found in Benguet State University main campus, to determine the distribution of the different Lepidopterans, to determine the number of collected species of Lepidoptera and to categorize the economic importance of the collected Lepidopterans. There were thirteen families of Lepidoptera identified in the entire campus and these were Crambidae, Hesperiidae, Lycaenidae, Pieridae Arctiidae, Nymphalidae, Papillionidae, Geometridae, Lymantriidae, Noctuidae, Saturniidae and Sphingidae. The families Crambidae, Hesperiidae, Lycaenidae, and Pieridae were observed to be present in the entire ecosystem. On the other hand, families Arctiidae and Nymphalidae were recorded in all the areas except in the field behind Administration. As for Papillionidae, it was seen in Organic farm, Forestry, BSU hallways and buildings and the field behind Administration. The families Geometridae, Lymantriidae and Noctuidae were only seen in Mites Predatory Rearing House, Forestry and BSU catwalk/buildings, while Saturniidae and Sphingidae were only present in BSU hallways and buildings. Under these families there were thirty two species collected and identified during the study namely: Areas galactina Hoeven, Utetheisa lotrix Cramer, Nyctemera adversata Schaller, Nyctemera lacticinia Cramer, Creatonotos gangis Linnaeus, Spilosoma curvata Donovan, Amata polymita Linnaeus, Pleuroptya ruralis Scopoli, Chrysaeglia magnifica Walker, Geometra sponsaria Bremer, Taractrocera luzonensis Staudinger, Zizina otis Fabricius, Lampides boeticus Linnaeus, Arctornis sp., Euproctis lutea Fabricius, Spodoptera litura Fabricius, Phalanta phalantha Drury, Danaus chrysippus Linnaeus, Melanitis leda Linnaeus, Hypolimnas bolina Linnaeus, Papilio demolus Linnaeus, Papilio helenus Linnaeus, Delias henningia Eschscholtz, Pieris brassicae Linnaeus, Eurema sarilata Semper, Delias benguetana Inomata, Endotricha flammealis Denis & Schiffermuller, Spoladea recurvalis Fabricius, Attacus atlas Linnaeus, Hippotion celerio Linnaeus, unidentified and unidentified. Four species were observed and identified as insect pests: Pieris brassicae Linnaeus, Eurema sarilata Semper, Zizina otis Fabricius and Papilio demoleus Linnaeus. On the other hand, 14 species were classified as beneficial. Lastly, 26 species were classified as visitors; these were the species only seen once regardless of location. The host plants of immature Lepidopterans present in the entire campus were brassicae (cabbage, lettuce, water cress, pechay, rape seed) for Pieris brassicae Linnaeus, giant milkweed for Danaus chrysippus Linnaeus, citrus for Papillio demoleus Fabricius, Lovi-lovi or batoko plum for Phalanta phalantha Drury, Slender panicgrass for Ypthima sp., legumes (peas) for Zizina otis Fabricius and Eurema sarilata Semper and Asian rice, maize and guinea grass for Melanitis leda Linnaeus.
