The continuation of the ‘Hatay Yellow’ generation will be ensured by scientific studies


In the production of “Hatay Yellow”, a local silkworm breed under protection in Hatay, with the joint scientific work of 4 universities, measures were taken against disease factors seen in larvae, and healthier cocoons that knit faster were obtained.

Expert academics have rolled up their sleeves to revive the “Hatay Yellow”, which was widely cultivated in Hatay in the past but is in danger of extinction because it is not maintained.

Working in collaboration with Emel Duman, who has been breeding silkworms for three generations in Hatay last year, the academics focused on “Hatay Yolk” both biologically and morphologically, from egg to cocoon, from cocoon to caterpillar and weaving.

As a result of the studies, the academics, who obtained healthy cocoons that knit faster by taking precautions against the disease factors seen in the larvae, and that they could also be knitted twice a year, shared this information with the producer Duman.

Growing “Hatay Yellow” in the basement of his house, Duman combined his academic knowledge with his experience, and this year he increased the production area to 100 square meters and obtained approximately 270 kilograms of product from the Hatay Yellow cocoon, which he bought 75 kilograms in a 30 square meter area last year.

Hatay MKU Agriculture Faculty Plant Protection Department Lecturer Prof. Dr. Feza Can told Anadolu Agency that “Hatay Yellow” is actually a cultural heritage.

Stating that “Hatay Yellow” is the 3rd local breed after “Bursa White Pied” and “Bursa White” in Turkey, Can continued as follows:

“Hatay Yellow was a breed that was produced until 45 years ago, but then it has not been produced for half a century, it is a bit sensitive and almost in danger of extinction because it is a domestic breed. Some studies were carried out on this issue years ago and these studies were limited with little information, “There has been almost no production and scientific studies for years. Here, together with our local producer Emel Duman, we are working to improve the growing conditions of the caterpillars of Hatay Yellow, to re-join production in Hatay and to protect this cultural heritage.”

It has been determined that cocoon is obtained twice a year.

Stating that they have obtained very new information in their studies, Can said that in a study conducted 50 years ago, it was stated that the color of the “Hatay Yellow” cocoon was orange, but they found that they could spin cocoons in more than 20 different color tones ranging from orange to orange yellow.

Stating that their most important finding is that the “Hatay Yellow” spins cocoon twice a year, Can continued his words as follows:

“It was known that these butterflies give offspring once a year. As a result of our research, we found that they can spin cocoons from Hatay Yellow twice a year. This means that the butterfly lays eggs, caterpillars hatch and spins cocoon once, but if the conditions of the larvae are improved in our studies last year, After a butterfly emerges from a good cocoon, we had the chance to obtain larvae and cocoons for one more season from the eggs laid by that butterfly, we brought this information to the literature as new information, and we turned these results into a scientific article, which was published and shared it with all researchers and producers. We have taken really big steps in improving the production conditions. This year’s production is already many times higher than last year, we have very beautiful cocoons and healthier butterflies. In the next production, we share this information with all producers who want and encourage everyone in Hatay to breed this breed. and protect our cultural heritage We want the bee.”

The increase in yield made the producer happy

Producer Duman said that he started growing “Hatay Yellow” last year and that the academic support provided motivated him a lot.

Explaining that he produces in the basement of his house, Duman said, “Hatay Yellow was a breed that I was a foreigner, I only saw when I was a child, but I never bred it. It both excited and worried me. We started last year with the support of my teachers, and even though it was the first year, everything went well, this year. Thankfully, we have achieved much better results.Last year, we grew a cocoon of 75 kilograms in an area of ​​30 square meters, and this year, we produced it more professionally in an area of ​​100 square meters, and the cocoon we obtained was 250-270 kilograms, that is, 3-4 times more in a year. We got the cocoon.” said.

Noting that 5 to 10 meters of fabric can be obtained from one kilo of “Hatay Yellow” dry cocoon, Duman added that the fabrics obtained from “Hatay Yellow” will be in great demand both in the country and abroad in the future.
