The silk industry in the Philippines is characterized by various activities such as silkworm egg production, cocoon production, reeling operation, weaving and made-up goods manufacturing.

Involved in the breeding and production of silkworm eggs of multivoltine and bivoltine strains are government institutions like the Philippine Textile Research Institute (PTRI) and the Serculture Research and Development Institute (SRDI). State Colleges and Universities (SCUs) such as the University of the Philippines at Los Baños (UPLB) and Central Luzon State University (CLSU) also handle egg breeding and production to ensure that silkworm eggs are diseased-free.

Together with FIDA, these government agencies are also involved in the hatching and rearing of silkworm eggs and rearing of silkworms up to the third instar before these are farmed out to cocoon growers. Third instar is an active period of growth during the larval stage occuring after the second molting which lasts from 3-4 days.

Cocoon production is possible through farmers' cooperatives or individual farmers who tend mulberry farms. Mulberry leaves are the sole food of the silkworms.

At present, there are about 12 cooperatives in the country that are engaged in cocoon production.

Since the closure of Ang Puno Silk (APSI), the only filature plant in the Philippines, on July 1997, conversion of cocoons into raw silk/silk yarn through reeling is now being done locally by PTRI, SRDI, some cooperatives and NGOs. Silk yarn productions by these agencies are primarily for research and development purposes although recently, they have partially supplied the needs of handloom weavers. PTRI can process about 545 kgs of dried cocoons per month while SRDI's monthly volume requirement is 2,520 kgs. The production of cooperatives and NGOs are limited because they only use hand reeling devices.
