The two-spotted spider mite, tetranychus urticae koch, is a phytophagous pest that can cause significant yield losses in cotton fields, and pathogenic organisms are very important to control them.

a study was conducted in some cotton fields at al-Hassakeh province through season 2019 to survey pathogenic organisms associated with two-spotted spider mite.

results showed the isolation and diagnosis of five types of pathogenic fungi with an infection rate of 13.33% results showed that five fungal species of 4 genera and one bacteria were identified.

the aspergillus Niger was the most frequently isolated fungus with 23.33 % frequency, followed by, neozygites floridana, aspergillus terreus, beauveria bassiana, penicillium sp.

and bacteria bacillus thuringiensis with a frequency of 18.66, 14.66, 13.33, 6.66 % and 23.33%, respectively.
