  Sunflower plants also attract tremendous number of insects of beneficial nature (predators, parasites and pollinators including honey bees). To see which beneficial insects are attracted to which genotypes and to what extent, observations were made on different genotypes of sunflower and the bee pollinators (melittophily) and aphid feeders, Coccinella spp. (aphidophagy) found on different genotypes were recorded. The highest number of honey bees (Apis spp.) was attracted to Suncross-24 and the lowest to SF-187. On SMH-9706, SMH-9707, Parasun-1, SF-187 and Hysun-33, the number of honey bees attracted was the lowest. It was concluded that SMH-9707 attracted the highest number of lady bird beetles (Coccinella spp.).The genotypes SMH-9706, Parasun1, SF-187, Hysun-33 and Suncross-24 attracted statistically equal number of lady bird beetles. Hysun-33 had the highest number of aphids (Aphis gossypii) and on all other genotypes except SMH 9707, the number of aphids was intermediate. SMH 9707 had significantly lower number of aphids than Hysun-33. The lady bird beetles were found feeding on aphids on different genotypes of sunflower. These beneficial insects helped regulate the population of insect pests and also helped in the pollination of sunflower plants.

  Thirty four maize cultivars were evaluated to observe their relative resistance against maize stem borer (Chilo partellus ) during Kharif, 2001. The varieties studied were Sarhad Yellow, EV-1097, Kissan, Babar, Agaiti-85, Gauhar, Margala, EV-2097, NC Br-1, NC BR2, C 6765-28, NARC 25 FI, NARC 251-1, NARC 25 12-2, NARC 25 12-2, NARC 25 12-21, C 6765-9, C 6765-11, C 6765-40 I, C 6765-40, C 6765-24, C 6765-28L, C 6765-29, C 1751-147-3 I, C  1751-54-2,  C 175-223, C 1752-16-2 I, C 1752-23-2 I, C 1752-43-3 I, C 1752-44-2 L, C 1752-14-2, C 1752-16-1, C 1752-17-3 and NARC 25 E. Variety EV-2097 was found to be most susceptible with 3.57% tassel infestation. Varieties NC BR-1, NARC 25 F I, NARC  25 1-1, NARC 25  12-2,  NARC  25  12-2 I, C 6765-40 I, C 6765-24, C 6765-24, C 6765-28 L, C 6765-29, C 1751-147-3 I, C 1751-54-2, C 1652-44-2 L and C 1752-17-3 were found to be resistant. The maximum percentage of dead hearts (3.56%) was recorded on EV-2097 and was observed  as  most  susceptible variety.  The  highly  resistant  varieties  with 0.707% dead hearts include NARC 25 F I, NARC 25 1-1, NARC 25 12-2, NARC 25-2 I, C 6765-28 L, C 6765-40 I, C 1752-23-2 I and C 1752-44-2 L.

  Thirty four Maize cultivars were evaluated to observe their relative resistance against maize stem borer Chilo partellus (Swinhoe). The varieties studied were Sarhad Yellow, EV-1097, Kissan, Babar, Agaiti-85, Gauhar, Margala, EV-2097, NC BR-1, NC BR2, C6765-28, NARC 25 FI, NARC 251-1, NARC 25 12-2, NARC 25 12-2I, C6765-9, C 6765-11, C6765-40 I, C 6765-40, C 6765-54 L, C 6765-24, C 6765-28L, C6765-29, C 1751-147-3 I, C 1751-54-2, C 1751-223, C 1752-16-2 I, C 1752-23-2 I, C 1752-43-3 I, C 1752-44-2 L, C 1752-14-2, C 1752-16-1, C 1752-17-3 and NARC 25 E. In case of stem damage, EV-2097 with damage of 4.479% was comparatively susceptible. Varieties that showed more resistance were NARC 25 F I, NARC 25 1-1, NARC 25 12-2, NARC 25 12-2 I, C 6765-9, C 6765-11, C 6765-40 I, C 6765-54 L, C 6765-24, C 6765-28 L, C 6765-29, C 1751-147-3 I, C 1751-54-2, C 1752-16-2 I, C 1752-43-3 I, C 1752-44-2 L and C 1752-16-1 with 0.707% stem damage. In case of difference in the height of healthy and damaged plants, the maximum difference of 33 cm was found in C 1751-147-3 I and NARC 25 F I whereas the minimum difference of -5 cm was observed in C 1751-223.
