Larval surveillance is the central approach for monitoring dengue vector populations in Indonesia. However, traditional larval indices are ineffective measuring mosquito population dynamics and predicting transmission risk. We conducted a 14-month ovitrap surveillance. Eggs immature mosquitoes were collected on weekly basis from an urban village of Bandung, namely Sekejati. Ovitrap-related indices, positive house index (PHI), (OI), density (ODI), generated correlated with environmental...

Farmers’ satisfaction with new superior varieties (NSVs) is a critical strategy for boosting their adoption. Out of 48 national NSV hybrids produced, only three, including Nasa-29, JH-37, and Bima-10, have been widely distributed at the farmer level. However, no studies carried out to establish farmers’ any three hybrid maize varieties. As result, main aim this study three-hybrid maize. The survey was conducted in South Sulawesi production districts: Bone, Gowa, North Luwu, representing...

Abstract One of the main obstacles to maize farming is extensive loss yields caused by investment Sitophilus zeamais (Motschulsky) (Coleoptera: Curculionidae) during storage period. This pest attacks kernels in active larval stage; they burrow, attack, and hide seeds. Some research reports that this attack can cause damage between 18-20%; conditions high water content, rate reach 30-40%. In addition direct damage, reduce product nutritional quality, seed weight, percentage germination, which...

Abstract In tropical climates, Sitophilus zeamais Motsch is the main pest of maize, often found when plants are still in field or storage warehouses. Damage to products stored materials has a significant effect on economic value because 1) ready for consumption and 2) have cost lot money from seeding, tillage, planting, maintenance, harvesting stage. Thus, slight damage due pests can cause losses compared attacks by other plant-disturbing organisms. Moreover, these insects will reduce...

Line (L)×tester (T) analysis is one of the breeding approaches to select inbred with good combining ability. Maize varieties erect and narrow leaf angles can increase yield under high-density populations. This study used line x tester assess ability gene action from several S5 lines idiotype high LxT maize hybrids. The research evaluated 44 hybrids derived crossing between 11 4 testers four commercial as controls February May 2022 using alpha lattice design three replications. results showed...

South Sulawesi is one of the largest rice production centers in Indonesia. Several important diseases plants, such as those caused by viruses and phytoplasmas, can be transmitted insect vectors, especially leafhoppers stem plant.
