ABSTRACT
Aleurocanthus camelliae was identified as a new species in 2011. The distribution of this species in worldwide is not widely known, including in Indonesia. These findings report the existence of A. camelliae in Indonesia as a new record based on morphological characters, previously identified as A. spiniferus. The study was carried out in August 2019 using an observation method in three locations with different altitudes around Mount Lawu. The result showed the species parasitized 13 medicinal plant species in two observation location (495 m asl and 1,200 m asl). Keywords: Aleurocanthus spiniferus, morphology, camellia spiny whitefly, invasive pest, medicinal plant.
ABSTRAK
Aleurocanthus camelliae diidentifikasi sebagai spesies baru telah dilakukan pada tahun 2011. Sebarannya diseluruh dunia belum banyak diketahui, termasuk di Indonesia. Laporan ini menyampaikan hasil pengamatan tentang keberadaan A. camelliae di Indonesia sebagai catatan baru berdasarkan karakter morfologi. Penelitiandilakukan pada bulan Agustus 2019 dengan metode observasi di tiga lokasi dengan ketinggian berbeda di sekitar Gunung Lawu. Hasil penelitian menunjukkan bahwa spesies ini telah memarasit 13 jenis tumbuhan obat di dua lokasi pengamatan pada ketinggian 495 m dpl dan 1.200 m dpl.

Fluctuation of Doleschallia bisaltide larvae (Lepidoptera: Nymphalidae) on caricature-plant (Graptophyllum pictum).Caricature-plant cultivation is often damaged due to the attack of Doleschallia bisaltide larvae. High reproduction ability ofD. bisaltide is a serious problem that need to be managed, therefore it will not inflict a financial losses. This study was aimedto determine the fluctuation of D. bisaltide larval population in the caricature-plant plantation in Kalisoro, Tawangmangu.The observations were carried out with a survey method on five observation plots for seven months from March to September2018. The data were analyzed by descriptive statistics and the Spearman rank correlation coefficient test. The results showedthat the population structure was changed during the observations with the highest larval population in May. The results ofSpearman rank correlation coefficient test showed significant and positive correlation between third, fourth, and fifth instarslarvae with the rainfall. The control of D. bisaltide can not only depend on the presence of natural enemies, therefore controlinterventions were needed especially at a suitable time and environment whne the population increased.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
