| Summary: | Melon Manis Terengganu (MMT) is a newly developed cultivar of Cucumis
melo that is exclusively planted in Terengganu and have been recognized as Terengganu’s
iconic fruit in 2015. Currently, the occurrence of pests and diseases is one of the major
constraints in MMT cultivation. Thus, the study on pest and disease incidence at different
growth stages of MMT plants were conducted as very little information about it on MMT has
been reported. Collection of pest samples and observation on diseases incidence were
conducted for eight weeks following the growth stages of MMT. A total of 176 individuals
belonging to six orders, 15 families and 37 species of insects were collected throughout this
study. Results revealed that red pumpkin beetle (RPB) (Raphidopalpa foveicollis:
Chrysomelidae: Coleoptera) was the most dominant pest found on almost all growth stages of
MMT. RPB were recorded in Week 1 until Week 5 with infestation on the MMT leaves and
stems that caused severe damage on the plants. The second dominant pest was melon worm
(Diaphania hyalinata: Crambidae: Lepidoptera) which was more abundant during foliage
expansion stage (Week 3), followed by leaf miner fly (Liriomyza trifolii: Agromyzidae:
Diptera) which was mostly found during the fruit maturation stage of MMT plants. A few
diseases were recorded from week three until week eight. The most dominant diseases recorded
were Cucurbits Yellow Stunting Disorder Virus (CYSDV), Powdery Mildew and Verticillium
wilt. Findings from this study may provide important information on pests and diseases of
MMT which is the first step in developing effective pest and disease control strategy. |
