Abstract

Bemisia tabaci is one of the limiting factors in chili farming, because it can cause damage both directly and indirectly as a vector for the Pepper yellow leaf curl virus (PepYLCV). Intercropping chili with corn is one of the efforts to control B. tabaci. Physically, corn plants are able to withstand the presence of B. tabaci, in addition to producing volatile compounds that are repellent to B. tabaci. This research was conducted to determine the optimal age of corn plants to be intercropped with chili plants. The research was conducted in Pleret District, Bantul Regency by testing five different ages of corn: 2 weeks after planting, 6 weeks after planting, 8 weeks after planting, 10 weeks after planting and control (without intercropping with corn). Weeks after planting are counted from the first day the corn seeds were planted. Yellow sticky trap (YST) was used to determine the presence of B. tabaci population in each treatment plot. YST was tied to bamboo sticks and placed on treatment beds with as many as 2 (two) traps per treatment plot. The distance between the yellow sticky trap and the plant was 30 cm, so the height of the trap was always adjusted according to the height of the plant. Observation of B. tabaci population was carried out every 5 days by counting the number of B. tabaci caught in yellow sticky traps. The results showed that the population of B. tabaci in the chili plots intercropped with corn was lower than that in the control plot, especially at the age of 6 weeks after planting (WAP). However, the intercropping of chilies and corn had no significant effect on the incidence of yellow disease in chilies.

Abstract

Fruit flies (Diptera: Tephritidae) are major pests in the horticultural sector. However, comprehensive information on their distribution across different habitats in Central Sulawesi is still lacking. This study aimed to assess the species diversity of fruit flies in three habitat types—urban, agricultural, and forest areas—in Central Sulawesi, Indonesia. Collections were conducted from November 2022 to May 2023 using Steiner traps baited with cue lure (CUE) and methyl eugenol (ME). Fruit fly specimens were identified to the species level, and diversity, dominance, and evenness indices were calculated. A total of 32 species and 10,393 individual fruit flies were collected across the three habitat types. The forest habitat exhibited the highest diversity and evenness indices, followed by agricultural and urban areas. In contrast, the urban habitat showed a higher dominance of certain species. The most dominant species were Bactrocera dorsalis (ME trap) and B. albistrigata (CUE trap). Notably, the presence of rare species found exclusively in forest habitats contributed significantly to the higher species richness observed there.

Abstract

Salicylic acid is one of the elicitor substances that can be used to reduce the level of damage of plants, both by pathogen and herbivore. The application of salicylic acid also affects plant growth and productivity. The impact of the salicylic acid application on a plant varies, such as depending on concentration, mode of application, and plant species. This research aimed to know the effect of different salicylic acid concentrations on mealybug development and papaya growth. The results showed that salicylic acid at concentrations of 100 mg/l slowed mealybug development and suppressed the amount of fecundity. Still, it caused a plant to grow smaller relatively. The application of salicylic acid at a concentration of 50 mg/l was the best treatment because it provided the best growth of papaya plants and suppressed the fecundity of mealybug.
