Abstract

Eggs and pupae 01 the Coccinel/a septempunctala L., Coccine/la
undecimpunclata l. and Chi/acarus bip < /em>uslu/afus L. can be stored al 8°C .. below their
zero of development. for several days. In general, viability of both stages decreased
by increasing the storage period. For eggs, the maximum or storage period. for the
three species, was detected after 3 days (71-83%) and decreased gradually to reach
(1-9%) after 15 days. For pupae, viability was 100 % up to 6 days and decreased to
(71-75%) after 27 days and reached (1.6-2.Y%) after 39 day of storage, The
relationship between number of living eggs and pupae with time obey the sigmoid
Saltzman equation.
