Abstract
Mulberry plant (Morus alba) is a plant that has social and economic importance. This plant development is often done to harvest the fruit and leaves. The social importance can be found in that this plant, especially in its leaves, is used in silkworm feed (Bombyx mori) and then silk is used in traditional clothes in Indonesia. Cultivation of mulberry plant (leaves and fruit) ideally by Integrated Pest Management (IPM) is necessary so that mulberry plants grow ideally and leaves have high quality and quantity without becoming a source of inoculum for pests and diseases of silkworm maintenance. Mulberry cultivation is generally carried out without using pesticide input so it is interesting in monitoring pests and natural enemies in the mulberry ecosystem. The research was conducted on two varieties of mulberry plants, namely Morus alba var. Kanva-2 and Morus cathayana in the same agroecosystem. Observation of pests and natural enemies was carried out using yellow sticky traps (YST) and pitfall traps (PFT). The orders and families found in the two varieties showed acroceridae family of 37.81% in the YST and hypogastruridae family with a value of 83.76% in the PFT observation.Keywords: IPM, Morus alba, natural enemies, pest, trapping.
Highlights
Mulberry (Morus spp.) is a plant that has important socio-economic value in Asia, especially Central and East Asia
The pitfall traps (PFT) used was a 90 mL volume cup filled with soapy water.Both of these sampling techniques are aimed at obtaining insects that have flying characteristics and are around the canopy of the plantations (YST), while the PFT is aimed at getting insects that cross and are active in the roots and soil around the mulberry plantations
Insects and arthropods caught in both traps (YST and PFT) were identified to the family level using the reference source Hymenoptera of the world: an identification guides to families by Goulet and Huber (1993), Australasian Chalcidoidea (Hymenoptera): a Biosystematic Revision of Genera of Fourteen Families, with a reclassification of Species, Borror and Delong's Introduction to the study of insects (2005), Insects of Australia Volumes 1A & 2A (1991), as well as specific national and international scientific journals
Summary
Mulberry (Morus spp.) is a plant that has important socio-economic value in Asia, especially Central and East Asia. The loss of yield due to pest attacks on mulberry cultivation is definitely high, considering the low use of pesticides (insecticides) in the crop, since the leaves can still be used (harvested 2-3 times a day as feed for silkworms (Bombyx mori). Mulberry pest control options are required to apply the Integrated Pest Control (IPM) concept and to make pesticides the last control choice so that mulberry leaves are not harmful when offered as feed to silkworm (B.mori). The objective of this experiment were to observe and to classify the pest incidence on two species of mulberry Morus alba var.
