| Abstract | ||
| A field experiment was carried out at the farm of Agriculture College University of Baghdad during the season 2007 to study the density of insects bests on 10 local melon cultivars (9 were collected from 5 provinces Baghdad, Babylon, Anbar, Dyala, Musel and imported cultivar Ananas). The results showed that the cultivar Hafez nafsah was the less preferring cultivar by the insects and recorded the less infections by all studied insects comparing with the other cultivars. The cultivar Shaoky was the most preferring cultivar by Raphidopalpa foveicollis (Lucas) and Epilachna chrysomelina Fab., they gave the highest means of infections which were 9.16, 5.46 insect/3 plants respectively, While the insects Aphis gossypii Glover and Thrips tabaci Lind. and Bemisia tabaci Genn. preferred the cultivar Ananas and gave the highest means of adults and nymphs numbers which were 41.66 , 207, and 98.80 insect/3 plants respectively. Results showed that Myiopardalis pardalina(Bigot) was prefer the cultivar Sukary, the highest mean of adults number was 5.20 insect/3 plants | ||
