Abstract

Mango farmers in Indonesia rely heavily on pesticides to control a variety of pests and diseases, with tephritid fruit flies being a major pest of the crop. To reduce pesticide use, Area-Wide Integrated Pest Management (AW-IPM) to control fruit flies was trialed and introduced in 2015 and has now been successfully implemented in several districts in West Java, Indonesia. This study surveyed pesticide use in mango farms adopting AW-IPM and those practicing conventional pest control methods. Purposive and Snowball sampling methods were used to select and interview 83 mango farmers to assess farmers knowledge and practices of pesticide use between the two groups. The farmers surveyed consisted of those that have adopted AW-IPM of fruit flies and conventional farmers, meaning those that did not adopt AW-IPM. The results of the survey revealed that compared to conventional farmers, the AW-IPM farmers had a high level of knowledge of pesticides and most of them were aware of pesticide-related environmental risks and adopted better and safer practices. Overall, storage of pesticides within living areas was reported by 10% of respondents, and most respondents (75%) adopted unsafe practices when disposing of used pesticide containers, such as selling them to plastic waste collectors. Half of all the respondents reported and experienced at least one symptom of a pesticide-related health problems. This study contributes to a better understanding of potential pesticide exposure and risks to mango farmers in Indonesia. A pesticide management training program for the mango farming community is badly needed.

Abstract

Formerly, the mirid bug has not been recorded for Hydrangea macrophylla (Thunb.), in Indonesia. Infestation of mirid bug was found on the leaves of Hydrangea in the vegetative growth phase from July 2023 to July 2024 in five hamlet fields at the ornamental farming center in Batu City, East Java. Plant samples were observed diagonally and five plants in each point were selected for samples. On each of the top ten leaves of the sample plants, the percentage of attack symptoms was carefully observed. Nymphs found during the observation were reared to imago, and adults were identified as Helopeltis cinchonae Mann (Hemiptera: Miridae). Insect pests, infestation symptoms, and egg locations were documented during the study. This is the first report of a pest causing significant damage to commercial Hydrangea plants in Batu, East Java, indicating the need to develop an integrated pest management strategy to support increased Hydrangea cut flower production in Batu.

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.
