Susceptibility of certain cantaloupe hybrids to major pests infestation in Sohag governorate

الملخص EN

Cantaloupe (Cucumis melo var.

cantalupensis, galia type) is an important cucurbitaceous vegetable crop sown in Egypt.

The present study was conducted at Shandweel Agricultural Research Station, Sohag Governorate during two summer successive seasons of 2017 and 2018 to investigate the population density of the aphid, Aphis gossypii Glover (Hemiptera: Aphididae); the whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae); the spider mite, Tetranychus urticae (Koch) (Acari: Tetranychidae) and the leafminer, Liriomyza trifolii (Burgess) ( Diptera: Agromyzidae) on cantaloupe crop and the susceptibility of ten local cantaloupe hybrids to infest by the previous pests, in addition to determine some yield characters.

Also, the effect of hair density on the infestation with piercing sucking pests was studied.

Data revealed significant differences between the tested hybrids in case of all pests and all horticultural characters during two successive seasons.

It was evident that number of hairs on cantaloupe leaves had positive effect on the aphid and two spotted spider mite, and negative effect on whitefly.

The present study can be suggest that the best hybrids are Shahd Zaman followed by Hybrid No.

8 and Hybrid No.

22, because of their high yield and their moderate infestation by most pests.

This recommendation was built up on the data of two seasons under experimental conditions at Sohag Governorate
