Ecological and Biological Studies on some destructive and beneficial insects on tomato plants in Egypt
A survey and biology of both destructive and beneficial insects related to tomato plants besides susceptibility of different tomato varieties to infestation with these destructive insects were studied at two governorates (Giza and Assiut) in Egypt. Results of these studies could be summarized as follow: A general survey of destructive and beneficial insects related with tomato plants was done at two different regions in Egypt: Giza and Assiut governorates, during four consecutive plantations; summer plantation (2012), winter plantation (2012-2013), summer plantation (2013) and winter plantation (2013-2014). Two different methods were used for determining these insects: 1- Sweeping net technique 2- Sampling counting technique 1- Sweeping net technique :1-Giza governorate: The collective data revealed 12 main insect pests belong to 7 Orders, i.e. Thysanoptera (one species ) , Neuroptera (one species ), Hemiptera (three species ), Homoptera (three species ), Coleoptera (one species ), Diptera (two species ) and Hymenoptera (one species ) associated with tomato plants . 1-Thrips tabaci Lind. was the unique representative of Thysanopterous insects. The counted number of this species was 903, represented13.7% during summer plantation (2012), while in winter plantation (2012-2013) it was 591 insects, and represented 20.36%. In summer plantation (2013) it was 1132 insects, represented 17.88%. In winter plantation (2013-2014) it was 511 insects, represented 18.03% of the general total of insects.
