Investigations on the forecasting and warning possibilities for the control of Cereal weevil [<em>Pachytychius hordei</em> (Brullé) (Col.:Curculionidae)] harmful on cereal in Central Anatolia.

Abstract

The movement of the fourth instar larvae of the cereal Weevil [(Pachytychius hordei (Brullé)] from the cereal spike to soil was followed in Sivrihisar (Eskişehir) in one barley and wheat field, next to each others in 1995. According to the results obtained from the studies, it was observed that the number of the spike with larvae has been decreased during the yellow maturing period, while the individuals caught by the sticky traps have been increased. 95.5% of the individuals (701 individuals) in the barley field were caught in 12 days and 4.5% (34 individuals) were caught in 7 days' time. 94.9  of the individuals (655 individuals) in the wheat field were caught in 10 days and the rest 5.1% (35 individuals) were caught in the 11 days time. It was determined that 745 individuals/m2 in barley field and 690 individuals/m2 in wheat field of the P.hordei fourth instar larvae for overwintering pupae has been found. This period lasted for 18 days on barley spikes. Only 3-9 individuals were found during the inspections in the barley field soil. As a result, it was shown that, the movement of the last instar P. hordei larvae from the spikes to soil for overwintering purpose has to be followed by means of the sticky traps and the relations between the unfavourable soil conditions that effect the population and the spring adult counts must be put forward. It was also conduced that this method could also be used for the forecasting and warning studies of the pest, for the IPM purposes.
