Abstract

The experiment was conducted in the Hamelmalo Agricultural College, Eritrea, from January 2017 to May 2017. This was done to study the attraction of major insect pest and diseases in three solanaceous crops (tomato, chilli and brinjal) grown singly and with mix cropping pattern. In Eritrea, solanaceous crops are important vegetables grown in different areas of the country.  Insect pest and diseases are the major biotic factors that limit the production of these vegetables in the country, these are recorded at the vegetative, flowering and fruiting stages for all three crops. The major insects pest, that is white fly, African boll worm, tomato fruit borer and leaf miner, were recorded on tomato followed by chilli and brinjal; whereas lace wing bug, leafhopper was attracted more on brinjal crops. Tomato and chilli were more susceptible for leaf curl virus and collar rot, while intensity of powdery mildew was maximum on tomato and minimum on chilli, whereas brinjal was least susceptible to any kind of diseases.

Key words: Tomato, Chilli, brinjal, incidence, severity, insect pest, diseases.
