Abstract

Strawberry (Fragaria x ananassa Duch) is a horticultural crop whose pollination partly depends on insects. Study was conducted in a strawberry field in Ciwidey-Bandung, with the objective to assess the contribution of flower-visiting insects to strawberry pollination. In this study, the contribution was assessed by pollinators abundance, duration of visits to flower, and pollination efficiency i.e. number of developed achenes, fruit weight and size, and ripening time. The study recorded four most frequent strawberry flower visiting insects which were two hoverfly species:  Episyrphus balteatus (Deg.) (47.3%) and Melanostoma sp. (33.8%); and two bee species: Lasioglossum sp. (7.0%) and Asian honey bee Apis cerana Fabricius (5.3%). Duration of visit per flower by the hoverflies was 7.75–10,00 minutes and by the bees was 0.25–0.79 minutes. Fruits developed from flowers that had received a single visit by each insect species had more number of developed achenes (1.6-1.8 times), higher fruit weight (1.8–2.3 times), bigger fruit size (1.2–1.3 times), and shorter ripening time (1–3 days), compared to those fruits developed from flowers not visited by the insect. The presence of bees and hoverflies play an important contribution to strawberry pollination in Ciwidey. Our findings have implications for increasing strawberry yield through management of insect pollinators.

Abstract

Ladybird beetle, Henosepilachna vigintioctopunctata Fabricius (Coleoptera: Cocinellidae) has a wide host plants belonging to family of Solanaceae. The species can be a serious pests of solanaceous crops, such as, eggplants and potatoes. The aims of the research were to study life table and to measure demography parameters of H. vigintioctopunctata fed by leaves of Solanum torvum, S. nigrum, S. melongena, and Brugmansia suaveolens. Results showed that the highest longevity (68.7 days, male and 79 days, female) occurred in H. vigintioctopunctata fed by leaves of  S. nigrum, followed by S. torvum (20.6 days, male and 31.7 days, female), S. melongena (1.5 days, male and 2.5,0 days, female, and B. suaveolens (1.8 days, male and 1.7 days, female). Based on demography parameters, the highest net reproductive rate occured in H. vigintioctopunctata fed on leaves of S. torvum (R0 = 2.11 individu), followed by S. nigrum (R0 = 0.64 females/female), S. melongena (R0 = 0.06 females/female), and B. suaveolens (R0 = 0.006 females/female). Generation time was high in H. vigintioctopunctata fed by S. nigrum (28.53 days) and S. torvum (27.42 days) compared to S. melongena (5,9 days) and B. suaveolens (2.5 days). Intrinsic growth rate of H. vigintioctopunctata was highest in S. torvum (r = 0.0094 females/female/day). Based on the life table and demography parameters, S. torvum is the most suitable plant for growth and development of H. vigintioctopunctata.

Abstract

This study examines the potential for rearing Apis cerana Fabricius honey bees in Taman Kehati Kiarapayung, West Java. Observations were conducted by installing 39 beehive in various locations and observing the flora that serve as bee food sources. A total of 50 plant species from 24 families were identified as bee food sources. Out of the 39 beehive, only 4 were successfully inhabited by bee colonies, showing a success rate of 10.3%. The observed colony growth ranged from 3 to 9 honey combs per hive. The main challenges in cultivation are the decrease in food availability during the dry season with very low rainfall, and pest disturbances such as wax moths (Galleria mellonella), wasps (Vespa sp.), and ants (Formicidae). The results of this study indicate that A. cerana beekeeping has the potential to be implemented in specific locations with sufficient food availability and effective pest management. This potential can serve as an additional source of income for the local community and support environmental conservation efforts by utilizing biological resources and biodiversity in a non-destructive manner at conservation sites.
