Ekspresi morfologi tiga jenis jeruk sebagai indikator ketahanan terhadap serangan Polyphagotarsonemus latus (Banks) (Acari: Tarsonemidae)

One of the important pests citrus seeds is silver mites (CSM) Polyphagotarsonemus latus (Banks) (Acari: Tarsonemidae). This study aimed to examine effect CSM attack on leaf morphology and resistance level three species. Three types citrus, namely Tangerine, Mandarin, Sweet Orange were used as test plants. The shoots tested for nutritional content five individuals invested young leaves that approximately 10 days old. Observations population made 7 after investment (DAI) further observations carried out every 4 days. results showed lowest abundance TPJ at 23 DAI was found in type Tangerine (0.5 ± 0.38 individual) Mandarin (0.25 0.16 individual). increased 11 15 DAI, began decline 19 DAI. Based Pearson correlation analysis, influenced by fat crude fiber leaves. also more resistant than other types. It can be concluded
