From theCambridge English Corpus Addition of vials with honey had no direct effect on the bruchid population or on theparasitoidprogeny. From theCambridge English Corpus These spores would probably accumulate in the occluded midgut of the developingparasitoid. From theCambridge English Corpus The longevity and daily fecundity of each femaleparasitoidwere recorded. From theCambridge English Corpus On several occasions, dissection revealed that hosts contained more than oneparasitoidlarva, indicating that superparasitism had occurred. From theCambridge English Corpus The identification by theparasitoidof the parasitized hosts was evident either during antennation or probing. From theCambridge English Corpus The diversity of parasitoids recorded here facilitates exploration of a number of issues associated withparasitoidassemblages on concealed hosts. From theCambridge English Corpus The proportion of eachparasitoidspecies relative to the total number of parasitoids that emerged was then calculated. From theCambridge English Corpus Similarly, the interaction between time ofparasitoidrelease and age of the berries at the time of infestation had no effect on rates of parasitism. From theCambridge English Corpus For this, six to eight-day-old experiencedparasitoidfemales from the no-choice tests and second to third instar nymphs were used. From theCambridge English Corpus As long as nontarget hosts are common and parasitoids can be reared in high numbers, the impact of theparasitoidmay be easily assessed.

From theCambridge English Corpus Aparasitoidof a polyphagous host might not be able to find or to access the host in all its feeding niches. From theCambridge English Corpus The effect of the plant on theparasitoidmay be manifested directly by the plant's physical and chemical characteristics. From theCambridge English Corpus Although no formal study ofparasitoidbehaviour was made, the search pattern of the parasitoids in this experiment appeared to be random. From theCambridge English Corpus These small differences favoured the co-occurrence of the twoparasitoidspecies on the same attacked trees. From theCambridge English Corpus Neitherparasitoidrefrained from oviposition in situations where its progeny were very unlikely to develop. From theCambridge English Corpus High bruchid populations in treatments withparasitoidintroduction were reduced by 50-75% compared to the control treatments without parasitoids. From theCambridge English Corpus Both species ofparasitoiddelay larval development until the host has reached full size and has entered the ground to pupate.
