| description | Studies on the nutritional requirements of the ladybird Menochilus
sexmaculatus were conducted with the objective to develope a chemicallydefined
artificial diet suitable for the growth and development of larvae and
adults of M. sexmaculatus
The formulated diet was presented following the paraffin coating
droplet technique. A diet of 1:3 dilution (1 part ingredients and 3 parts
water) was used for feeding the first instar larvae, while 1:1 dilution was for
later instars and adults.
Studies on yeast requirement showed that 7 g yeast hydrolysate
improved survivorship, growth performance and longevity of M.
sexmaculatus. As such this amount of yeast was mixed with 2 g casein
hydrolysate, 5.5 g sucrose and 15 ml distilled water in a paraffin-vaseline ratio of 2:1 to form the basic diet. In the study on amino acid requirements,
02 g of each of the 1O-essential amino acids was added to the basic diet
either together or separately. In a similar study on vitamin requirements,
02 g of different vitamins were added to the basic diet either together or
separately. Results showed that M. sexmaculatus required methionine and
histidine for the longest longevity, and pantothenic acid for the highest
survivorship. |
