The body of a grooved mealybug usually has colors between reddish and brownish, measuring approximately half a centimeter in its adult stage. Its back has a covering, as if it were a white waxy shellwhich has grooves throughout, a characteristic from which it derives its name.

Metamorphosis and reproduction

The metamorphosis of the canalada mealybug pest is recognized as incomplete. This usually makes three changes during its existencetransforming them into the type of mealybug that moves the most. Newly hatched nymphs will be housed on the underside of the leaves of our plant, showing a color closer to orange than to the brownish that they show in the adult stage.

In its adult stage, these move to the branches and trunks of plants and treeswhere they will begin the breeding process. Incredibly, no males are needed for this reproductive process to take place, as there is very little male population in corrugated mealybug colonies.

The mechanism of reproduction without the intervention of the male is called Parthenogenesis, whereby the unfertilized ovum is segmentedfor different reasons ranging from chemistry, temperature and electricity among others. In this way, the female sex cells will be able to develop a being without the intervention of fertilization.
