Normally a female lays eggs repeatedly at 6-9 day intervals and about 10 times in a season.

If there is more than one egg, hatching occurs at 5 day intervals.

The nestlings hatch in approximate 3 to 5 day intervals.

The sulfur is applied shortly after flowering, followed by two more applications at 15 day intervals.

At two day intervals, cells were trypsinized and counted with a hemacytomter.

Each egg is laid at 2 to 3 day intervals.

Plumer planned four steps at six day intervals, to give time to move artillery and supplies forward.

Females continue to lay subsequent egg pods at 18 day intervals until they are killed by the freeze in November.

That being said, I have seen lower-security settings (such as 90 day intervals) used with success as well.

Four additional doses are then given at 14 day intervals following transplantation.
