Abstract

Development in the agricultural sector is dominant in the Maluku Province region, because the majority of the population works in agriculture. One of the agricultural locations is Telaga Kodok Hamlet which has a fairly large planting area, so people tend to cultivate vegetable crops such as chickpea plants (Phaseolus vulgaris). In the cultivation of bean plants, both quality and quantity are affected by pest attacks, so it is necessary to pay attention to proper control techniques. One of the pests that attack chickpea pods is pod borer (Etiella zinckenella). This study aims to determine the intensity of damage to chickpea pods and to determine the crop cultivation system to suppress the development of Etiella zinckenella pests. This research was conducted in farmers' plantation areas in Telaga Kodok Hamlet, Hitu Lama Village, Leihitu District, Central Maluku Regency in March 2024. The research methods used included surveys and direct observations in bean planting areas to observe Etiella zinckenella pest attacks and assess the intensity of damage. The results of this study showed that the type of pest that attacked bean plants in the farmers' area in Telaga Kodok Hamlet was pod borer (Etiella zinckenella) with an average attack intensity of 48.13% and was classified as moderate. Bean cultivation techniques such as tillage, fertilization, use of varieties, sanitation, pest control have not been implemented properly. In controlling pests, farmers rely more on the use of synthetic pesticides with concentrations and mixing methods that are not in accordance with the rules of use.

Abstract

The cacao pest MOT (Conopomorpha cramerella) is the main pest of cocoa plants. The damage caused by this pest to cocoa plants in West Seram Regency, Inamosol District is unknown. This research aims to determine the size of the population and the intensity of damage caused by the pest Conopomorpha cramerella. This research uses a survey method with a simple random pattern, while the sample plants are determined by as many as 10 plants found on each sample farmer randomly. In contrast, the sample fruit is determined by as many as 3 fruits found on each sample tree. Data taken includes variety, seed origin, land area, planting pattern, plant age, plant spacing, pruning, sanitation, weed cleaning, fertilization, insecticide application, and general condition of the research location. This research shows that the intensity of damage to cocoa pods in Uraur village is (62.72%) and is classified as severe. The total larval population in Uraur village is 8.63 individuals.

Abstract

This study aims to obtain the types and morphological characteristics of fruit fly pests and compare the number of fruit fly populations trapped in various types of chili plants. This study used Methyl Eugenol with a dose of 1.5 ml / cc in three chili planting locations: Poka, Taeno and Kranjang. Observations of the population of fruit fly pests caught were carried out on the 3rd day after the trap was installed and repeated every 3 days until the 42nd day. Observations were carried out in the morning at 07.00 - 09.00 WIT. The results of the study showed that fruit flies found in chili plantations in Poka, Kranjang and Taeno villages, namely B. dorsalis and B. umbrosus were found in the three sample villages, while B. carambolae was only found in Taeno village. The highest population was in Taeno village 2,027 with an average of 289,57 individuals, then Kranjang village at 1,294 individuals with an average of 184, 86 individuals and the lowest in Poka village with a population of 852 individuals, with an average of 121,71 individuals.
