Özet

The Hatay yellow strain silkworm (Bombyx mori L.), which is in danger of extinction, is one

of the most important local cultural heritages of Türkiye. Bacterial pathogens of silkworm

are highly destructive and cause mostly acute diseases. The aim of this study was to

determine the bacterial diversity and potential pathogenic bacterial species in infected and

dead larvae of Hatay yellow race. A total of 16 bacterial isolates from Hatay yellow race

were identified according to their morphological, biochemical and molecular

characteristics. The bacterial isolates isolated from infected and dead larvae of Hatay

yellow race were Staphylococcus sp. (BM-1), Staphylococcus xylosus (BM-5),

Staphylococcus succinus (BM-7), Bacillus thuringiensis (BM-8), Bacillus subtilis (BM-9),

Bacillussp. (BM-10), Staphylococcus saprophyticus (BM-16, BM-19), Klebsiella sp. (BM-17),

Staphylococcus arlettae (BM-18), Pseudomonas aeruginosa (BM-20), Enterococcus mundtii

(BM-21), Pantoea agglomerans (BM-22), Kluyvera intermedia (BM-23), Serratia sp. (BM24), Mammaliicoccus sciuri (BM-25). The high bacterial density and number of species

indicate that Hatay yellow race is highly susceptible to bacterial diseases. Insecticidal

activity studies revealed that species belonging to Bacillus and Staphylococcus genera are

important pathogens of hybrid silkworm culture and Hatay yellow race.
