It remains unknown whether there are available gall rust resistant seed sources of Falcata (Falcataria moluccana (Miq.) Barneby & J.W.Grimes) in the country or elsewhere. This study was conducted to obtain baseline data for future progeny selection of gall rust resistant clones of Falcata in the region. The objectives were to determine whether there are available seed sources or mother trees in the region that are resistant to gall rust, and whether gall rust infection has negative effects on the growth of Falcata. The trial (with 130 mother trees as treatments and four replications) was assessed in November 2020- or five-years following establishment in 2015. Mean percent incidence (15.0 ± 5.0% to 80.0 ± 14.1%) and severity (3.75 ± 1.25%) to 35.0 ± 16.95%) of gall rust varied significantly among treatments indicative of genetic diversity among mother trees. The incidence ranged from ‘occasional’ to ‘widespread’ while severity ranged from ‘low’ to ‘high’ with mother trees 99 (Mutia, Zamboanga del Norte) and 106 (Magsaysay, Baliangao, Misamis Occidental) emerged as the most resistant of all. Height and diameter were positively related to gall rust incidence and treatments only, although none of the mother trees with resistant traits had superior growth. There was however indication of growth and disease tolerance tradeoff where trees with higher gall rust incidence tend to grow bigger perhaps to compensate for any negative impacts from gall rust infection.

Knowing the pest species first is necessary for the formulation of pest control method. In this study an assessment of termite infestation in the academic buildings was conducted. All wooden materials both furniture and structural member were inspected for signs of termite infestation. Soldiers of termites found infesting wooden structures were collected for identification. The data gathered during actual inspections include moisture content of infested wood, coatings (painted or not), type of wood in service (furniture or structural member) and materials used (lumber or plywood). A regression analysis was run to determine if the mentioned factors or combination thereof can best explain the rate of infestation. A total of 28 buildings were inspected. All of the buildings showed signs of termite infestation. Pieces of furniture were mostly infested with drywood termites while structural member were infested mostly by subterranean termite. However, most of the buildings have empty tunnels with no active termite population. There were only 3 species of subterranean termites collected and identified viz., Macrotermes gilvus Hagen, Coptotermes gestroi Wasmann and Microcerotermes losbañosensis Oshima. Regression analysis showed that none of the factors or combinations thereof can explain the variation in the extent of damage caused by termites.
