Abstract

The presence of synaptonemal complexes were checked in dividing chromosomes as evidence for meiotic division in germinating sporangia. Continuous urografin gradients were used to separate out the various phases of germinating sporangia, the nuclei were removed and embedded for ultrastructural studies. Meiotic inhibitors were applied to germinating sporangia to retard meiotic division to highlight the synaptonemal complexes. At an early phase of sporangial differentiation dividing nuclei developed with synaptonemal complexes. Meiotic inhibitors and stimulators may be used to control sporangial germination for an induction of a high meiospore count. This may be of crucial importance in the utilization ofCoelomomyces spp. as a biological control agent of mosquito species.
