The number of circulating hemocytes is increased in cactE8/cact9 third instar larvae compared to wild-type.
cactE8/cact9 larvae are viable at 24 and 48 hours after fertilisation. More than 80% of the larvae survive to 120 hours after fertilisation and progress into pupal stages. Less than 1% of these animals eclose, the majority dying as pupae. Approximately 40% of larvae have melanotic capsules.
Strong ventralizing phenotype: lack of all dorsally and laterally derived structures and the expansion of the ventral epidermis around the entire circumference. Expansion of twi expression in terminal regions.
