INVESTIGATIONS ON FECUNDITY OF APHELENCHUS AVENAE

Aphelerachus avenae feeding on fungal cultures in petri dishes responded to adverse conditions by slowing egg laying not by laying fewer eggs. The females required a continuous supply of food to produce eggs; after starving they resumed egg laying when given food and laid at the same rate as nonstarved individuals and for the same length of time. The different hosts tested did not affect the average number of eggs laid per female but did affect the rate eggs were laid. Individual females laid more eggs when there were 4 in a petri dish than when they were alone. © 1969 BRILL.
