The goal of this project was to develop an integrated pest management strategy for the control of a powder-post beetle (Dinoderus minutus F.). This species causes serious damage in Philippine bamboo. Developmental threshold and thermal constants were examined and natural enemies and fungi associated with beetles were investigated. Finally, the seasonal beetle occurrence and costs and benefits of prophylactic treatments to control the damage were investigated under Philippine conditions.

520 $a The goal of this project was to develop an integrated pest management strategy for the control of a powder-post beetle (Dinoderus minutus F.). This species causes serious damage in Philippine bamboo. Developmental threshold and thermal constants were examined and natural enemies and fungi associated with beetles were investigated. Finally, the seasonal beetle occurrence and costs and benefits of prophylactic treatments to control the damage were investigated under Philippine conditions.
520 $a Female powder-post beetles deposited eggs mainly in the metaxylem at an average of 9.1 eggs per day. The average development periods for eggs, larva, pupa and egg to adult were 5.4, 43.8, 4.6 and 53.6 days, respectively, at 30°C.
520 $a An unknown mite species caused 88% mortality to eggs and could prove to be a potential biocontrol for the beetle. Spores of Beauvaria bassiana and Metarrhizium anisopliae topically applied or sprayed at higher spore concentrations (1:10 and 1:100) caused significant mortality to D. minutus and could regulate beetle populations.
520 $a Imperfect fungi constituted the major fungi isolated from the beetles. Further studies are suggested to determine the relationship between these fungi and D. minutus.
520 $a Beetle populations generally peaked from February to early June and were low to non-existent in July to October in the period studied (1998--2000). Bamboo starch content and temperature significantly influenced beetle populations. Starch was the major determinant factor in the regression model [(Y/starch = -106.57 + 27.43(starch)] developed to predict beetle population. The linear relationship between temperature and starch production in bamboo culms suggested that monitoring temperature may be a practical method to predict beetle occurrence.
520 $a Application of 0.0001% a.i. deltamethrin in water or kerosene to freshly cut culms provided complete protection for five weeks against beetle attack. Supplemental treatment may be applied after that protection period. Kerosene or paraffin alone did not increase insecticidal efficacy.
520 $a The economic benefits of prophylactic treatment were twelve times greater than the added cost of treatments demonstrating the value of treatment for maintaining bamboo quality. Losses due to beetle damage will be further reduced once the results of this study are incorporated in a pest management program.
