Comparitive biology of Spilarctia obliqua in Papaya (Carica papaya), Star Cluster (Pentas lanceolata), Cashew nut (Anacardium occidentale) and Pumpkin (Cucurbita pepo) agroecosystems

Studies related to the Biology of the Bihar hairy caterpillar, Spilarctia obliqua (Walker) in Kerala, especially in Northern Kerala is scanty. There were no comparative biology studies of Spilarctia obliqua (Walker) on different crops in Kerala. The present studies were undertaken during 2018-19, under room temperature (28-340C). The data on comparative biology of Spilarctia obliqua on different hosts inferred that Female lays around 148 to 232 eggs. The eggs were creamy white when laid became pale yellow in colour before hatching. The maximum number of eggs were recorded from Carica papaya (148-232) and Pentas lanceolata (150-230), while minimum number of eggs were recorded from Anacardium occidentale (148-230). Larvae develop through six instars in 20 to 22 days with an average of 21 days at 28-32 °C. The present studies, the comparative biology of Spilarctia oblique is important for to know the best host that support the development of Spilarctia obliqua and can be used for mass rearing. Similarly, the information of life history parameters of Spilarctia oblique on different host plant species will help to make efficient strategies to control this economic pest.
