“…(Miridae). Helopeltis predominantly attack young Eucalypt leaves and shoots causing lesions, curling and drying of the foliage [47]. In addition to pest infestations, tree plantations may also suffer from water stress that causes leaf shedding however most trees retained younger leaves to cope with water deficit [48].…”

Eucalyptus is a diverse genus from which several species are often deployed for commercial industrial tree plantation due to their desirable wood properties for utilization in both solid wood and fiber products, as well as their growth and productivity in many environments. In this study, a method for monitoring the health status of a 22.78 ha Eucalyptus pellita plantation stand was developed using the red-green-blue channels captured using an unmanned aerial vehicle. The ortho-image was generated, and visual atmospheric resistance index (VARI) indices were developed. Herein, four classification levels of pest and disease were generated using the VARI-green algorithm. The range of normalized VARI-green indices was between −2.0 and 2.0. The results identified seven dead trees (VARI-green index −2 to 0), five trees that were severely infected (VARI-green index 0 to 0.05), 967 trees that were mildly infected (VARI-green index 0.06 to 0.16), and 10,090 trees that were considered healthy (VARI-green index 0.17 to 2.00). The VARI-green indices were verified by manual ground-truthing and by comparison with normalized difference vegetation index which showed a mean correlation of 0.73. This study has shown practical application of aerial survey of a large-scale operational area of industrial tree plantation via low-cost UAV and RGB camera, to analyze VARI-green images in the detection of pest and disease.

“…Homona spargotis, in the current study, was seen along with the tea mosquito bug, Helopeltis theivora Waterhouse, 1886 (Hemiptera: Miridae), a sapsucker and other mirid species on the commercial stands of E. grandis × E. pellita clone in Sumatra (KKADAN et al, 2020c). Potential monitoring and control measures of H. spargotis include the use of light traps (HULCR et al, 2007) and sex pheromone traps (for monitoring) (WHITTLE et al, 1987).…”

All potential pests (e.g., defoliating lepidopterans) of Eucalyptus L’Hér. (Myrtaceae) are important to be recorded because of multiple species from this plant genus are ubiquitously planted in forest plantations across the tropics, including Sumatra, Indonesia. The objective of this study was to record, for the first time, a species closest to the avocado leafroller, Homona spargotis Meyrick, 1910 (Lepidoptera: Tortricidae) on a Eucalyptus grandis W. Hill × Eucalyptus pellita F. Muell. hybrid in Sumatra with the insect species identification performed via molecular analysis. The used molecular protocol was able to identify a similar, yet distinct insect species to H. spargotis through analysis of its larvae, which defines its geographical distribution to Sumatra and identified a host species (i.e., E. grandis × E. pellita) for this insect.

“…Tetracona amathealis, collected in the present study while feeding on a E. grandis × E. pellita hybrid, has been previously recorded to feed on E. tereticornis (HERBISON-EVANS et al, 2013). This insect was seen along with the tea mosquito bug, Helopeltis theivora Waterhouse, 1886 (Hemiptera: Miridae), a sapsucker and other mirid species on the commercial stands of E. grandis × E. pellita hybrid in Riau (KKADAN et al, 2020b). (Walker, 1859).…”

Tetracona amathealis (Walker, 1859) (Lepidoptera: Crambidae) is previously known from Australia and New Guinea, where it feeds on the native Eucalyptus tereticornis Sm. (Myrtaceae). The objective of this study was the report, for the first time, T. amathealis in Indonesia as well as to record new host plants for this insect. Were collected manually from a Eucalyptus grandis W. Hill. × Eucalyptus pellita F. Muell. hybrid commercial plantation in Riau, Sumatra, Indonesia and a sample sent for identification via molecular analysis. Our findings revealed that the molecular approach used (through sequencing of its mt-COI gene) successfully allowed the identification of the species as T. amathealis. This insect is recorded for the first time in Indonesia on a new host, a E. grandis × E. pellita hybrid.
