Abstract

Papaya is an important commercial crop in various industrial sectors. Calina is the predominant variety liked by many communities and growers in Indonesia because of its superior traits and relatively stable price. In its cultivation, phytophagous mites infestations tremendously decrease the yield of papaya. Additionally, cropping system may affect the diversity, stability, and abundance of arthropod communities. This study aimed to evaluate the effects of planting system against mite population abundance. The research was conducted in Malang during 7 months of dry season (average of rainfall was 4.58 mm/month) in papaya monoculture and polyculture of papaya and sugarcane. Within each plantation, 25 papaya trees were randomly selected as samples. From each tree, 2 leaves were taken out based on the maturity i.e. young and mature leaves. Sampling was done at 1 week interval. Collected mites were counted, identified, and their population abundance were monitored. The results indicated that the most abundant of phytophagous mite population per leaf was Tetranychus urticae (74.75 ± 36.10), followed by Panoncychus citri (15.91 ± 7.45), and the lowest was Brevipalpus phoenicis (0.48 ± 0.55). While other was predatory mite Neoseiulus sp. (5.49 ± 4.21). The average of mite population abundance per leaf was greater on monoculture (26.01 ± 15.57) than polyculture system (15.42 ± 8.53), also it was higher on mature (26.48 ± 13.43) rather than on young leaves (14.95 ± 9.83). The study revealed that the polyculture system could greatly suppress the abundance of phytophagous mites, and likely promoted the biocontrol services by predatory mites.
