तेल ताड़ के बगीचों में लीफ वेबवर्म, एक्रिया मायरिकी (लेपिडोप्टेरा: डिप्रेसारिडे) के लिए जैव नियंत्रण एजेंट Oil palm, Elaeis guineensis Jacq.(Family: Arecaceae) is the richest source of vegetable oil with high yield levels of more than 5 tonnes of oil per ha per annum compared to other oil seeds crops that give less than 1 ton.  The productivity of the crop is often challenged by water stress, drought, biotic stresses like pests and diseases and constraints related with nutrient management. Since irrigation is given at regular intervals, the micro climate with high humidity is created, which makes congenial conditions for pests and diseases development. It is reported that the oil palms in...

तेल ताड़ का पत्ता वेबवॉर्म, एक उभरता हुआ गंभीर कीट और तेल ताड़ के बागानों में इसका प्रबंधन Oil palm (ElaeisguineensisJacquin: Arecaceae) is known to be the highest edible oil yielding perennial crop, capable of yielding 4-5 MT of palm oil and 0.4-0.5 MT palm kernel oil with good planting material, irrigation and proper management. However, the productivity is not achieved due to infestation by a wide range of fauna which include insects, birds, mites and mammals, apart from diseases, nutrient deficiencies, water stress etc. As the oil palms grow and attain tallness, the leaves of adjacent palms are overlapped, thereby preventing sunlight penetration in the plantations, a more favourable environment is...
