Extract

The three species of Laemophloeus commonly associated with stored products have been shown, by a survey of recorded information, to be cosmopolitan and to occur on a large variety of foodstuffs.

The egg, four larval instars and pupa of L. minutus have been described briefly and the life-history outlined.

Mated females of Laemophloeus minutus lay eggs continuously throughout their long life at the rate of about 0·5 eggs per day at 17°C. rising to 4·0 eggs per day at 30°C. Humidity changes over the range 55–90 per cent. R.H. have little effect on the rate of oviposition. Oviposition is stimulated by the constant presence of the male.
