“…Impacts of climate change, patterns and inputs of agricultural cultivation, R. amorphophalli will be the main obstacle to the development of porang in Indonesia through trade and exchange of infested tuber, bulbil and seed planting materials. This pest has a wide range of host plants, including 6 families and 9 genera, namely Dioscoreaceae, Zingiberaceae, Asteraceae, and Araceae (Colocassia and Amorphophallus) [8,12]. In a pest integrated management program, these host plants need to be adequately controlled to avoid the re-infestation of commercial porang.…”

“…In its natural habitat, porang is exposed to minor pests and diseases, such as, Cercopora sp. and Sclerotium rolfsii that can slightly reduce quality of tubers [6,8]. In August 2021, nearly all harvested porang tubers stored in the warehouse of ILETRI field station, Malang were heavily damaged by the insect showing symptoms in the form of white powder on the surface of the infested tubers.…”

“…Mealybugs (Hemiptera: Pseudococcidae) declared as economically important insect pests worldwide [12,20,22]. These pests are polyphagous, may attack many crops that cause the host growth and the tuber storage problems [5,8,14]. The information concerning mealybug in porang in Indonesia are scarce [22].…”

Since 2020 porang (Amorphophallus muelleri Blume) has been declared as an important commercial crop grown in Indonesia. Recently, porang tubers a coated of a distinct white waxy substance was observed at seed storage. The symptoms pose a threat to tuber vigour quality due to the intensive infestation on stored tubers. This sap- sucking insect sucks the juice leading to desiccation and shrivelling of tubers. This study aims to identify the sap- sucking insect pest attacks the storage porang tubers. The studies carried out at ILETRI. Identification of the caused insect species was done by observing symptoms visually, morphological identification of adult females using Compound microscope Olympus Bx43 in 40 X magnification, and tuber germination and growth of 250 infested tubers in the field. Regarding to the specific symptoms whose soft body coated of a distinct white waxy substance and morphological measurement of the average length of the adult females (862.62±46.3 μm with range between 764 - 904 μm), it’s supposed caused by mealybug in Rhizoecus amorphophalli (Hemiptera:Pseudococcidae). Our founding revealed that R. amorphophalli is first discovered as causal agent of a mealybug pest of porang in Indonesia and turned out to be very detrimental because their infestation caused 90 percent of infested porang tubers unable to germinate and grow.
