ABSTRACT The longevity and fecundity of adult Phoracantha recurva and Phoracantha semipunctata were strongly affected by diet. Female P. recurva fed a diet of Eucalyptus pollen and sucrose solution lived 34-56% longer than females fed diets containing other types of pollen, ground dog chow, or sucrose solution alone. Diet had no significant effect on longevity of P. recurva males. Similarly, longevities of P. semipunctata females were increased 48-71% on the Eucalyptus pollen diet compared with the other diets. Male P. semipunctata also lived longer on the Eucalyptus pollen diet than most of the other diets. Fecundity was dramatically affected by diet, with P. recurva females fed the Eucalyptus pollen diet laying approximately 4-8 times more eggs than females on the other diets. Eucalyptus pollen also increased the fecundity of P. semipunctata females approximately 3-5-fold. Diet resulted in only minor effects on egg size and percent egg hatch for both beetle species.

  • Article: Development of the Powderpost Beetle (Coleoptera: Bostrichidae) at Constant Temperatures

    ABSTRACT: Development of Dinoderus minutus was studied under laboratory conditions at five constant temperatures (15, 18, 25, 28, and 30°C) to estimate developmental thresholds and thermal requirements of the egg, larva, pupa, and egg-to-adult stages. Adults began to burrow along the grain into bamboo pieces within 24 h after cutting and continued across the grain. Female beetle oviposited an average of 9.1 eggs in the ensuing 24 h, all in the metaxylem. The average period for development of eggs, larva, and pupa were 5.4, 43.8, and 4.6 d at 30°C, respectively. The development rate data were regressed through the x-axis to derive the thermal constants of 4.3, 6.8, and 4.5°C and thermal requirements of 113.6, 909.1, and 96.2 DD to predict D. minutus egg oviposition to hatch, larva-to-pupa development, and adult emergence from pupa, respectively. The thermal threshold for egg-to-adult development was 6.4°C, with total thermal requirements of 1,111.1 DD. Oviposition, emergence, and thermal requirements for development of the various stages of D. minutus may be used for postharvest pest management of bamboo.
