Many fig wasp species have dimorphic males. These males often mate in
different localities; one typically disperses before mating whereas th
e other does not disperse. In 1979 a model was developed for offspring
allocation in dimorphic fig wasps, but it assumed that females only l
ay a single egg per fig. This assumption is not realistic and preclude
s any effects local mate competition (LMC) may exert on morph abundanc
e. I develop a model without these restrictions and show that the opti
mal proportions of each morph is determined by two parameters. Firstly
, the proportion of the non-dispersing morph is affected by the mean n
umber of females that oviposit in a patch. This effect is due to the n
egative correlation between LMC between brothers and the number of fem
ales that oviposit in a patch. Secondly, the proportions of both male
morphs correlate with the expected proportion of females which will ma
te with each morph. The separation of the two parameters generalizes t
he model to any other species which is spatially structured and which
has two male morphs or even two alternative mating strategies. A compa
rison of two models shows that parent-offspring conflict involving mor
ph ratios will not have far reaching consequences. I test these models
using the 1979 model's data and both models accurately predict the va
riation in morph ratios in six species of dimorphic fig wasps.
