| Summary: | Kalamansi citrus (Citrofortunella microcarpa) is one of many horticultural commodities
cultivated in Bengkulu, Indonesia. Insect pests are organisms that interfere growth and
economic value of crops such as citrus. Insect pests on citrus plants result in decreased
production ranging from 50%–77% worldwide. Knowledge of types of pest insects and their
natural enemies is very important to designing effective control strategies. This study aimed to
identify insect pests associated with Kalamansi citrus in Bengkulu. The number of Kalamansi
citrus sample plants observed was 20 (selected randomly) and the citrus plants observed
were about six years age. The results showed that Kalamansi citrus was infested by four
orders and eight families of insects, including Hemiptera: Pentatomidae (Rhynchocoris
poseidon Kirk), Hemiptera: Aphididae (Toxoptera citridicus Kirk), Hemiptera:
Pseudococcidae (Planococcus citri Risso), Hemiptera: Flatidae (Metcalfa pruinosa (Say),
Thysanoptera: Thripidae (Scirtothrips dorsalis Hood), Lepidoptera: Gracillariridae
(Phyllocnistis citrella Stainton), Lepidoptera: Papilionidae (Papilio demoleus L.), and
Diptera: Tephritidae (Bactrocera spp.). The dominant pests on Kalamansi citrus belonged to
the orders Diptera (fruit flies) and Hemiptera. Some insect pests attack oranges and cause
direct damage to crops by eating the affected plant parts, whereas others act as vectors for
viruses and other pathogens. Some insects eat leaves, flowers, and fruits directly. |
