Description
Summary:Aphids ( Aphis gossypii) are the main problem in patchouli plants ( Pogostemon cablin ). The presence of aphids on patchouli plants is very worried by farmers, because it can damage patchouli plants by feeding the leaf which can reduces plant growth. Therefore, it is neccesary to learn more about biological of A. gossypii on patchouli plants. A gossypii was taken from Nino Park, Syiah Kuala University and Lamteuba, Aceh Besar. The patchouli used was the result of maintaining cuttings for two months to be used as an object of observation. Infestation A gossypii was carried out in 10 observation polybags. Observations were made by looking at the development time of A. gossypii including the nymph phase (instar I-IV) and imago A. gossypii. The experiment showed that the life cycle of A. gossypii lasted for 23.8 ± 4.76 days. A. gossypii had four instar stages, duration time needed each instar is 2 days, it means the duration of nymphal stage A. gossypii on patchouli is 8.8 days. The lifecyle of imago A. gossypii is 15 days. There were two types of imago, winged and wingless aphids imago, caused the population density of aphids on a plant.
