ABSTRACT
Laboratory trials were undertaken to examine the effect of diets (honey, pure honey, sucrose, tap water and unfed) on longevity of Apanteles (= Dolichogenidea) metesae Nixon, a solitary and larval endoparasitoid of oil palm bagworm, Metisaplana Walker (Lepidoptera: Psychidae). Results showed that A. metesae females fed 20% sucrose lived significantly longer than females fed on 80% and 90% honey, pure honey, 50% sucrose, tap water and unfed females. However, there was no significant difference in longevity of A. metesae fed on 10%, 20%, 30%, 40%, 50%, 60% and 70% honey solutions. Result showed that sucrose is a more suitable diet for A. metesae females as compared to honey.
ABSTRAK
Kajian untuk menguji kesan beberapa jenis diet (madu, madu asli, sukrosa, air paip dan tiada makanan dan minuman) terhadap jangka hayat spesies Apanteles (= Dolichogenidea) metesae Nixon, sejenis larval endoparasitoid terhadap ulat bungkus kelapa sawit, Metisa plana Walker (Lepidoptera: Psychidae) telah dijalankan di makmal. Hasil kajian menunjukkan bahawa A. metesae betina yang diberi makan 20% sukrosa hidup lebih lama secara signifikan berbanding A. metesae betina yang diberi makan 80% madu, 90% madu asli, 50% sukrosa, air paip dan yang tidak diberi makanan dan minuman (kawalan). Walau bagaimanapun, tiada perbezaan yang signifikan terhadap jangka hayat A. metesae yang diberi makan 10%, 20%, 30%, 40%, 50%, 60% dan 70% larutan madu. Secara keseluruhannya, hasil kajian ini telah menunjukkan bahawa larutan sukrosa adalah diet yang lebih sesuai untuk memanjangkan jangka hayat A. metesae betina berbanding larutan madu.
Key words: Apanteles metesae, Metisaplana, diets, oil palm, longevity.
