To ensure oviposited
eggs were flushed into pitchers and those eggs had a chance to hatch, this experiment was conducted 3 d after a heavy rain.
The Chrysididae female takes more time to crawl through the nest than to oviposit
. After which, she quickly leaves the nest, crawling along the roof without the male noticing her.
However, pure or almost pure male clutches may be also produced when many foundresses (5+) oviposit
simultaneously in a one-foundress syconium (Ramirez-Benavides, pers.
in September and October, whereas R.
alone and unguarded, unlike other UAE Anax spp.
In this paper, we adopt the second approach and compare the phenotypic variance in offspring sex ratios produced by females of different pollinating fig wasp species when they enter a fruit and oviposit
alone (defined as single foundress sex ratio).
Parasitoids were significantly more likely to oviposit
(rather than host feed) when they had higher egg loads and when they encountered larger hosts (Table 2; [ILLUSTRATION FOR FIGURE 1 OMITTED]).
No non-native mosquito has ever been found to oviposit
and survive to adult eclosion within the pitchers in nature (Petersen et al., 2000).
solidaginis host races due to plant preference: each host race preferentially mates and oviposits
on the host plant from which they were reared.
It is not clear how many eggs a female wasp oviposits
at one time, but Lathrop and Newton (1933) reported commonly finding multiple eggs and up to four first instar wasp larvae in one maggot.
The probability that the second pair oviposits
in either of the two empty plots (1-1-0 or 1-0-1 pattern) = 2/3.
Differential mortality of the sexes might occur within a host if a female oviposits
at least one offspring of each sex in a single host.
