Abstract
Food type and light colour significantly affected population growth of Sancassania (= Caloglyphus) berlesei (Michael). It was found that when fertilized female of S. berlesei was fed on Baker's yeast, fish meal, meat meal, poultry feed and Rass cheese and exposed to a 14L : 10D h. photoperiod (L= light , D= Dark) of blue, green, red and yellow light colours during 40 days after treatment, Rass cheese and Baker's yeast harboured the highest numbers of mite individuals, while meat meal and fish meal gave significantly lower ones. The lowest value was recorded with poultry feed. Counts of S. berlesei on Rass cheese, Baker's yeast, meat meal, fish meal and poultry feed for 40 days after treatment were 8199.10, 7198.90, 725.70, 683.20 and 658.50, respectively. However, colour of light significantly affected numbers of S. berlesei . The highest values were counted with blue light (3730.68), followed by red (3470.36) and green (3403.88) lights, while the lowest value (3367.40) was recorded with yellow light. Formation of hypopial stage of S. berlesei as influenced by food type and colour of light during experimental time also was discussed. Generally, these results may be of practical implications in monitoring and management numbers of S. berlesei.
