Abstract
Recently, we reported brood parasitism in the tiny predatory mite Neoseiulus californicus (Acari: Phytoseiidae); adult females of this species prefer to add their eggs to a cluster of eggs of another predatory mite species, Gynaeseius liturivorus (Acari: Phytoseiidae), which guards its own eggs against egg predators.
Here, we investigated the cues used by the blind N. californicus to detect eggs of G. liturivorus.
We show that N. californicus locates oviposition sites of G. liturivorus using volatiles emanating from eggs of the latter species.
Adult female G. liturivorus spent more time guarding oviposition sites that contain more eggs, which resulted in a higher per capita survival of the eggs. We therefore hypothesized that N. californicus would prefer oviposition sites with more G. liturivorus eggs.
Indeed, N. californicus preferably laid their egg at oviposition sites containing more than six G. liturivorus eggs, which corresponds to the average number laid by a female G. liturivorus during one day.
Our results suggest that N. californicus uses egg volatiles to localize oviposition sites of G. liturivorus, where the eggs of the former are effectively protected against egg predators.

6. File overview
Each data sheet is associated with data in the above paper.
Data on residence time of hosts on oviposition sites and predation on host eggs by thrips larvae are shown in the sheets residence time and egg predation respectively.
Data Sheet of Fig. 1
"treat" means two types of odour source (i.e., the presence and the absence of egg odour). "eggs" means the number of parasite eggs laid on sites with either of two odour sources.
Data Sheet of Fig. 2
"bars" means the order of choice tests shown in Fig. 2 of the paper from the top. "treat" means the number of host eggs on each oviposition site, and "eggs" means the same as Fig. 1.
Data Sheet of residence
"treat" means the number of host eggs on oviposition sites. "time" means residence time when host females remained on oviposition sites
Data Sheet of egg predation
"treat" means the number of host eggs on oviposition sites. "eggs" means the number of eggs killed by thrips larvae.
