Components of the female sex pheromone of the yellow stem borer, Scirpophaga incertulas

AbstractA commercially-available, hand-applied PVC resin formulation of the sex pheromone of the striped rice stem borer, Chilo suppressalis (Walker) was used to control the yellow stem borer, Scirpophaga incertulas (Walker), in a 20 ha mating disruption trial in West Bengal, India, in 1992. Indirect measures of mating disruption were used to compare the pheromone-treated plot with an untreated control plot and a farmers' practice plot where a conventional pesticide control regime was practised. The results showed that the level of ‘white head’ damage in the pheromone-treated plot was significantly lower than that recorded in other treatment plots and that the relative percentage of the larvae of the two major stem borer species, S. incertulas and Chilo polychrysa (Meyrick) found in the region changed from 88% S. incertulas in the farmers' practice plot to 65% in the pheromone-treated plot. The yields of grain and straw recorded in the pheromone-treated plot were significantly higher than in the untreated control plot but not significantly different from those recorded in the farmers' practice plot.

Natural Parasitism

Three species of parasitoids viz., Telenomus dignus Gahan, Trichogramma japonicum, Ishii and Tetrastichus schoenobii Ferriere were recorded from the egg masses of rice yellow stem borer, Scirpophaga incertulas (Walker) in a field study. The extent of parasitism was high during Rabi (43.33 – 93.33 %) and low during Kharif (0 - 40.00 %). Parasitism by T. dignus was maximum in October (50.00 %), T. japonicum, in November (23.08 %) and T. schoenobii in February (55.55 %). dignus and T. schoenobii in combination parasitized maximum number of egg masses (41.82 %). Multiple parasitism by the three species was high in December (8.33 %) and January (7.14%). Parasitic potential was maximum, when T. schoenobii alone parasitised the egg masses followed by T. dignus and T. schoenobii in combination. Host density in the field influenced the extent of parasitism.
