    Efficacy of plant extracts against Varroa mites (Varroa destructor) of honey bees (Apis mellifera L.)
    (Journal of Biodiversity and Environmental Sciences (JBES), 2023) Tabafunda, Minerva J.; De Castro, David T.; Pajarillo, Rolyne Mae C.; Soliba, Mishima P.; Garcia, Adora A.; Acosta, Mac Donald C.; Dangle, Emmanuel O.
    The acaricidal and insecticidal effects of 12 selected botanicals against Varroa destructor and Apis mellifera were investigated. Crude ethanol leaf extract of botanicals was tested for acute toxicity using the full exposure method in a 16×4×3 Factorial Complete Randomized Design including negative control (water) and three commonly used chemical miticides (amitraz, tau fluvalinate, and thymol). The results revealed four promising miticides whose efficacy of plant extract, as measured by LC50, was in the following order of potency: Ocimum basilicum (biday)(15.80)> Vitex negundo (lagundi) (23.79) > Cymbopogon citratus (lemon grass) (27.73) >Gliricidia sepium (28.83). Due to their high selectivity index, they are also considered less toxic to honey bees.

    Improved feed efficiency and nutritional property effects of honey from Apis mellifera L. as an additive for broiler chickens’ drinking water
    (DMMMSU Research and Extension Journal, 2023-12) Tattao, Rosemarie O.; Panas, Joseph A.; de Castro, David T.; Soliba, Mishima P.; Calimpang, Ison A.; Pajarillo, Rolyne Mae C.
    Antimicrobial usage is particularly high in poultry production. Honey as a water supplement to poultry has been explored as a natural and safe antibiotic alternative. This study aimed to investigate the effects of different levels of honey as a water supplement on broilers' growth performance and chemical properties. Five dietary treatments were used: no supplement (T1), commercial electrolytes (T2), 5mL honey (T3), (7.5mL honey (T4), and 10mL honey (T5) per liter of water. The experiment used 150 1-day-old Cobb-400 broiler chicks, assigned to five treatments with three replications of ten (10) birds each (N=30) employing the Complete Block Design (RCBD) in three blocks. Results indicated that 5mL/L-10mL/L honey supplementation led to a significant (p < 0.05) decrease of 4.3% to 7% in feed consumption compared to those with electrolytes. Similarly, using 5mL/L of honey showed 12.5% lower FCR compared with T2 and 24.3% compared with T1. However, a higher level of honey was comparable to T2, indicating that honey supplementation improved feed utilization and reduced feed cost at a certain level. Results of the proximate analysis, particularly on moisture content (MC), crude protein (CP), crude fat (CF), and total carbohydrates ((TC), revealed numerical differences. Samples with 5mL/L to 7.5mL/L levels of honey showed a higher MC, CP, and TC content and lower CF than T2. This implies that honey as a drinking water supplement offers practical advantages in feed consumption and efficiency and in improving the chemical and nutritional properties of chicken meat. A choice for healthier production.

    Insect visitors of rambutan (Nepheliumlappaceum),Black plum (Syzygiumcumini) and cashew (Anacardiumoccidentale)
    (DMMMSU Research and Extension Journal, 2020-12-01) Tangalin, Merlito D.; Dangle, Jaime; Pajarillo, Rolyne Mae C.; Soliba, Mishima P.
    The honeybees are labelled as the champion pollinators.Through theirpollination services,the quality of seed set, forage crops, and fruit yield improves.Field experiments were conducted to determine the effect of introduced honeybees (ApismelliferaL.) in the number and weight of harvested fruits of the three (3) tropical fruit-bearing trees (rambutan, black plum, cashew).Three (3) fully grown rambutan, black plum, and cashew trees approximately 10 years old were selected. The t-Test was employed using 20 samples pertreatment(open pollinated flowers, T1in three (3) replicationswherein twenty (20) panicle samples were selected) togather the needed data.During the onset of blooming,one (1) standardbee coloniesmajor pollinator aside from the other insects in the area was placed within the vicinity of the plantation crops. Results of the study on the pollination of insect visitors on the experimental fruit trees showed significant differences between the open pollinated flowers (T1) and enclosed treatments (T2). In terms of harvested, percentage and weight of developed fruits of rambutan, black plum and cashew, results revealed that trees introduced with honeybee as pollinatorssignificantly produced more fruitsand heavier developed fruits than those in enclosed flowers (T2).

    Profiling of the Beekeeping Industry:
    (DMMMSU Research and Extension Journal, 2022-12-01) Pajarillo, Rolyne Mae C.; Masiong, Pablo L.; de Castro, David T.; Soliba, Mishima P.; Panas, Joseph A.; Acosta, Mac Donald C.
    Beekeeping is a viable agribusiness enterprise of small scale farmers, and other rural and non-rural people. Despite the many returns bees give including the increasing industry stakeholders and trained beekeepers, local honey production remains very low; hence, this study was conducted to determine the profile and status of bee enterprises in Region 1 and CAR. Demographic profile, level of motivation along the STEEP factors, and enterprise profile, were gathered employing semi-structured questionnaire. Interviews and secondary data were also employed. Results revealed that majority (78.95%) belong to the working age population (21-60 years old). There were more male (75.44%) and married (78.95%) beekeepers but women participation (24.56%) was also observed. Beekeepers had a relatively high literacy rate and 98.1% completed bee trainings. More than half (68.42%) were officers/members of community organizations but they were just part-time beekeepers because they had other/main source of family income. Environmental influences e.g., vegetation, were “very highly motivating factors in engaging to. Apiary sites conformed to standards of location appropriateness and resources availability, and all beekeepers practiced migration for higher honey production. They had total colony holdings of 1,097.5 standard (10-framer), with an average of 27.44 colonies each. This classified them as commercial beekeepers based on the Philippine National Standards. Lowland and upland honey flows fall in April to May and October to December. An analogous process flow of honey harvesting, processing and storing was confirmed. Start-up investment is ₽22,010.00. Average yearly operational expense per standard colony incurred by lowland beekeepers from 2000 to 2019, was ₽19,367.84 which is a little higher than the upland costs due to land and truck rental, and labor fees during migration and production periods. CAR beekeepers had a higher ROI of 20.02% than those in Region 1 with 4.39%. Natural environmental harms i.e., bee-eater predator birds, typhoons, were on top of the reasons why beekeepers discontinued their apiculture projects.
