    (2010) Orenset, J.C.; Bauzon, B.C.; Imperial, M.L.R.; Pacumbaba, B.P.
    Dipha (Conobathra) aphidivora Meyrick (Pyralidae: Lepidoptera) is recorded fQl' the first time as a predator of coconut mealybug, Sangicoccus sp. (Eriococcidae: Hotnoptera» in the Philippines . . . Some aspects of its biology and ecology were studied to detennine its suitability as a biological control agent against Sangicoccus sp. The life history ·of D. aphidivora was investigated following the. ~tablishment of a rearing procedure. The incubation period of the egg was 4.64±0.70 days. The four larval. inStars larva were completed in 5.52±O.92, 3.40±0.91, 2.83±0.72 and 3.4O±1.04 days, respectively. Adults emerged from pupae after 7.68± 0.99 days. Adult longevity was 6.83 ± 2.30 days. The life cycle of D. aphidivora lasted for 32.42±3.63 days. Voracity tests showed that the four larval instars of the predator consumed an average of 150 mealybugs.
