Title: Integrated Management of the Green Pit Scale (Palmapsis phoenicis (Roa) (Homoptera: Asterolecaniidae) on Date palm in Abu Hamad (Sudan)
Author: Ali, Elhadi Ahmad Mohammed
Abstract: The present study investigated the extent of green pit scale insect in Abu Hamad area. A Series of small scale field experiments were carried out in Abu Hamad during Nov 2011 to June 2012 to evaluate the efficacy of two components of integrated management of green pit scale insect (Palmapsis phoenicis (Rao)). These are pruning and Imidacloprid as Confidor. The objectives of the study is to manage the numbers of insects. The pruning as 25% from the tree and insecticide 35ml/tree. The experiment was conducted in collaboration with four farmers, ten trees were chosen five treated and five untreated in every orchard were conducted. The counting was made before pruning, before insecticide application and also after insecticide application. This research was carried out under the infection pressure prevailing in the area of experimentation. Result indicated that the mortality of adult and immature stages were higher in pruning and insecticide application in treated than untreated ones. The study was also intended to assess and survey the spreading extent of green pit scale (Palmapsis phoenicis). The study also intended to show the effect of pruning and insecticide application (Confidor 200sl, the group Neonicatinoids, ai imidacloprid) and on productivity. The results indicated the percentage of the decreased number of insects was 30% when applying insecticide and pruning. The study indicated that the increase of production was 25% . Date palm trees which were treated with the pruning and insecticide developed normally, compared with untreated ones. These results were discussed and the main perspectives emerging from the thesis were concluded along with suggested future lines of the research. It was noticed through the survey that the insect is spreading very fast.
