Abstract

The aim of the present work is to study the Biology and Economic damage of Panonychus ulmi (Koch) in the orchards of Ganderbal, Kashmir Valley, Jammu & Kashmir, India. For the sake of convenience 3 orchards were selected from Lar, 3 from Safapora and 3 from Kangan. According to the plan visits were conducted and the results were noticed. To obtain economic damage, the net productivity of selected orchards with heavy infestation was measured in relation to the non infested orchards of same area, containing equal number of trees. The binomial (Presence-Absence) of sampling scheme of European red mite was also done during the project. 5 to 10 leaves from five to ten trees scattered throughout a zone selected for investigation. Leaves were scanned with the help of hand lens to determine whether or not mites were present. The table results clearly indicate that the orchard selected from Kangan location was heavily infested followed by Safapora and, Lar was least infested. The results were f

Conclusion

The work undertaken was completed in the set time of 5 months and it was conclude that, European Red Mite ¬(Panonychus ulmi Koch) is a major tree fruit pest in Jammu and Kashmir attacking fruits particularly apple with specificity on its Red Delicious species. However, mild attack on apricot and peach was also been reported from various parts of valley including Ganderbal. Moreover its attack on some generas of Roseacea family in the vale has also been brought in notice. The fecundity of the European Red Mite (Panonychus ulmi) which was the core part of the study of biology of the said pest was determined in the laboratory. To calculate cumulative mite days, average number of mites per leaf of two successive mite counts was taken, it was multiplied by the number of days between the count, and the result was added to the running total. Since mite population have a single peak, the peak population level is related to the total number of mite days. The binomial (Presence-Absence) of sa
