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.
eques

Females
oviposit 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.
