Abstract
A study was conducted to investigate the synchronize effect of intercropping and insect growth regulator (IGR) for the management of apple codling moth Cydia pomonella. The results revealed that Apple + Trifolium (Trifolium alexandrinum) + Match� (T3) afforded minimum mean fruit drop (2.07) and lower percent infestation (36.41%), followed by Match� (T1) (46.74%), Apple + Trifolium (T2) (59.49%) and maximum were in control plot (T4) (67.36%). Likewise, minimum mean number of C. pomonella adults (1.30 male moths/traps) were monitored in the Apple + Trifolium + Match� (T3), whilst all other treatments including control were the maximum number of C. pomonella adults male moth catch in the traps. The percent parasitism of Ascogaster quadridentata (Hymenoptera: Braconidae) and Hyssopus pallidus (Hymenoptera: Eulophidae) were significantly higher in the treatment T3 i.e.32.83 and 34.66% respectively. Maximum yield were recorded in the T3 (94.75 � 0.62 kg/plant) followed by the plots treated with T1 (83.75 � 1.19 kg/plant), T2 (77.00 � 1.17 kg/plant) and Apple sole (T4) (57.75 � 0.14 kg/plant). Maximum losses (39.05%) were avoided in T3, whilst the percent gain in yield (64.07%) due to control measures was also attributed to T3. Hence, application of Match� sprays in the presence of Trifolium alexandrinum as intercrop in the apple orchard play pivotal role in the management of C. pomonella.
