Sažetak
Aphids (Insecta: Aphidoidea) are one of the most important group of agricultural pests worldwide. They have often caused serious, economic damages on variety of crops. Control is sometimes very difficult mainly due to resistance to conventional pesticides. Unlike chemical pesticides, plant extracts showed many benefits to environment, biodiversity and human health. This research was conducted to determine the efficacy of different water and alcohol concentrations of indigenous (local variety) and imported garlic (Alium sativum L.) extracts on aphid (Hyalopterus pruni Geoffr.). Experiment was performed in laboratory conditions, using Petri dishes previously sheathed with filter paper, in which aphids were transferred. In each Petri dish 15 individuals were placed. Water and ethanol garlic extracts were dissolved in three concentrations (100%, 50% and 25%). Insects mortality was checked after 24h and 48h. The percentage mortality was calculated and corrected using Abott’s formula. Significant differences among treatments and control were found. Within 24h the highest effect (>80%) on aphids showed 100% water concentration, aswell as all ethanol solutions. After 24 h 25% water concentration showed very low efficacy (9.99%). After 48 h mortality was higher, more than 75% at all concentrations.
