Abstract

Mango (Mangifera indica Linn.) has been cultivated in the study area for several years and considered by some farmers as primary source of their income. There are about 104 thousand of mango trees grown commercially in Nueva Ecija, General Trinio and Peñaranda in particular low and quality harvests, pests and diseases occurrence and cost of production inputs are among the problems claimed by the growers. There have been efforts to develop suitable crop production technologies to address the problems and improve the quality through pest management. These technologies are promoted through S and T [Science and Technology] based project by PCAARRD [Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development] to different regions. This study assessed the influence of integrated crop management technologies on the occurrence of insect pests and diseases and yield in mango in General Trinio and Peñaranda, Nueva Ecija. The pests were monitored and yield was taken in two production cycles 2013 to 2014. The six insect pests monitored in the study included leafhoppers (Idioscopus clypealis Lethierry), thrips (Scirtothrips dorsalis Giard), cecid fly (Procantarinia spp.), fruit fly (Bactrocera philippinensis Drew and Hancock and B. occipitalis Bessi), seed borer (Noorda albizonalis Hampson) and twig borer (Callimtopus capito Pascoe), while three on diseases, the scab (Sphaceloma mangiferae Bitanc) and Jenkins, anthracnose (Colletotrichum gloeosporoides Penz.), and stem end rot (Lasiodiplodia theobromae (Pat.) Griff and Maubl.). Results revealed that the level of insect pests and disease occurrence was influenced by extent of crop management technologies (such as pruning, growth regulation, flower induction, nutrient management and pest disease management) followed by the farmers. Likewise, the fruit yield was increased and quality profile of fruits were improved, hence farmers must be encouraged that these technologies must be properly implemented.
