“…These conditions inferred that the late afternoon application had a more positive impact on lowering insect attacks. Nurmasyah (2014) also reported a similar phenomenon when treated cocoa plants with citronella extracts to control Helopeltis antonii. The lower attacks severity and percentage of attacks on late afternoon application were predicted to have a relation with the persistency of the active ingredient of the insecticides.…”

“…Most insect species are poikilothermic creatures; thus, daily temperature affects the existence and position of the insect within the plants (Nowinszky & Puskás, 2013). A study conducted by Nurmasyah (2014) on applying citronellal extract to control Helopeltis antonii on cocoa revealed that the late-afternoon spraying gave different mortality on the insects than morning and mid-day applications. This research evaluated the efficacy of leaf extracts of T. sinensis and T. diversifolia and A. indica applied at different times to control aphids Macrosiphoniella sanborni Gillete in chrysanthemum considering the effects of botanical and time of application.…”

Pest management in the agricultural process has faced worldwide economic and ecological issues related to chemicals usage. Botanical insecticides have long been considered promising alternatives to control pests because botanicals reputedly pose a minor threat to the environment and human health. Some studies have evaluated several botanical insecticides to control aphids in chrysanthemum. The research was conducted under plastic house conditions at the Indonesian Ornamental Crops Research Institute from January to December 2018. Leaf extract of T. sinensis, T. diversifolia and A. indica at the concentration of 3 and 3.5 g/l, processed oil of C. nardus at the concentration of 2.5 and 5 g/l and synthetic insecticide Imidacloprid 1 g/l were sprayed in the morning or late afternoon. The results showed that aphid attacks severity and percentage of attacked plants were lower when the insecticides were applied in the late afternoon. Slightly softer than synthetic chemicals, the leaf extract of T. sinensis at 3 g/l suppressed the aphid development more effective for about 55.93% than other botanicals treatments. On reproductive properties, the leaf extract of T. sinensis at 3 and 3 g/l and T. diversifolia at 3 g/l induced a higher percentage of open flower for more than 65% than synthetic insecticides, Imidacloprid.

One of the problems in papaya cultivation is the high attack of pests and diseases. The mealybug, P. marginatus L (Hemiptera: Pseudococcidae) is currently found to attack papaya plants. The infestation of mealybugs greatly affects the yield and quality of fruits. The purpose of this study was to determine the effect of the concentration of citronella oil on mealybugs on papaya plants. The study for the observation of mortality and fecundity used a Randomized Block Design (RAK), with 4 treatment levels of citronella oil concentration, namely 0 (control), 0.5 mL/L, 1 mL/L and 2 mL/L. Observation parameters included preference level of papaya mealybugs on the aroma of citronella oil, repellency, fecundity and mortality of mealybugs, with the application of citronella oil. The results showed that citronella oil has the potential to be used to control papaya mealybugs. The application of citronella oil at concentrations of 0.5, 1 and 2 mL/L showed repellent activity against mealybugs, reducing fecundity and causing mortality. The higher the concentration of citronella oil applied, the more potential to control mealybugs. However, the application of citronella oil must be considered for its impact on plants. Too high a concentration can cause toxicity to plants. Keywords: Citronella oil, mealybug, papaya ABSTRAK Salah satu kendala dalam budidaya pepaya adalah tingginya serangan hama dan penyakit. Kutu putih, P. marginatus L (Hemiptera: Pseudococidae) saat ini ditemukan banyak menyerang tanaman pepaya. Infestasi hama kutu putih sangat berpengaruh terhadap produksi dan kualitas buah. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh konsentrasi minyak serai wangi terhadap kutu putih pada tanaman pepaya. Penelitian untuk pengamatan mortalitas dan keperidian menggunakan Rancangan Acak Kelompok (RAK), dengan 4 taraf perlakuan konsentrasi minyak sereh wangi, yaitu 0 (kontrol), 0,5 mL/L, 1 mL/L dan 2 mL/L. Parameter pengamatan meliputi preferensi (tingkat kesukaan) hama kutu putih pepaya terhadap aroma minyak serai wangi, daya repelensi, keperidian, serta tingkat kematian (mortalitas) hama kutu putih dengan pemberian minyak sereh wangi. Hasil penelitian menunjukkan bahwa minyak sereh wangi berpotensi digunakan untuk pengendalian hama kutu putih pepaya. Aplikasi minyak sereh wangi pada konsentrasi 0.5, 1 dan 2 mL/L menunjukkan aktivitas repelen (penolak) terhadap kutu putih, menurunkan angka keperidian dan menyebabkan kematian (mortalitas). Semakin tinggi konsentrasi minyak sereh wangi yang diaplikasikan, semakin berpotensi mengendalikan hama kutu putih. Namun, aplikasi minyak serai wangi harus diperhatikan dampaknya pada tanaman. Konsentrasi terlalu tinggi bisa menyebabkan toksisitas pada tanaman. Kata kunci: Kutu putih, minyak sereh wangi, pepaya
