As the eggs of this species hatch over a period of ten or more days, undoubtedly the last stem mothers to hatch are still producing during the last week of June. However, the maximum period of productive activity is during the last week of May and the first week of June, that is, while the young fruits are beginning to set and start active growth.

Page 751 - ... accurately determined. The eggs begin hatching in the spring from a week to ten days earlier than those of the green apple aphis or the rosy apple aphis. In the past three years the first eggs hatched on April 19 (1916), April 17 (1917), and April 15 (1918). Hatching continues over a considerable period, usually about ten days if the weather is favorable. The stem mothers become mature during the last few days of April and the first week of May.

While this is in accord with the three-factor hypothesis, • it is, of course, equally in keeping with a two-factor or even a one-factor hypothesis. None the less, white segregates from supposed 27:37 lots afford the most nearly crucial test of the hypothesis. It is well known...
