Add a definition Percentage emergence of parasitized offspring was not significantly influenced by whether they developed in single or superparasitized mealybugs. From theCambridge English Corpus Encapsulation of parasitoids is a common feature ofmealybugparasitism and has been argued that it can increase the success of superparasitism. From theCambridge English Corpus Mortality from parasitism was determined by dissecting about 100 randomly selected mealybugs under a stereomicroscope on each sampling occasion. From theCambridge English Corpus This indicated that the difference inmealybugmortality from parasitoids and predators on the two host trees varied according to themealybugspecies. From theCambridge English Corpus There is one other feature of themealybuggenome that is of interest. From theCambridge English Corpus The ants sometimes remove the dead outer bark near soil level to facilitate the feeding of the mealybugs. From theCambridge English Corpus This suggested that there was a degree of synchrony between peak numbers of the threemealybughosts and the rates of parasitism and predation. From theCambridge English Corpus The results of this experiment suggest that on an average 25 186 plaque forming units represent the size of themealybuggenome. From theCambridge English Corpus All these mealybugs are normally ant-attended but are rarely associated with fungi. From theCambridge English Corpus Therefore, it appears that inoculative biocontrol programmes should be applied early in spring in order to curb the increasingmealybugdensity later in summer. From theCambridge English Corpus A female parasitoid was introduced into the oviposition arena containing two mealybugs (one from each host category). From theCambridge English Corpus The parasitized hosts were obtained by exposing an individualmealybugto a parasitoid female for the deposition of a single egg. From theCambridge English Corpus Because of the agility of predators,mealybughost mortality due to these agents could not easily be determined. From theCambridge English Corpus The rate of attack by parasitoids and predators of the various developmental stages of the threemealybugspecies differed. From theCambridge English Corpus Percentage predation was thus determined from direct counts of characteristicmealybugremains on sample units. From theCambridge English Corpus The effect of the time between ovipositions on the discrimination between unparasitized and conspecific-parasitized mealybugs was studied using these variable egg-load parasitoids. From theCambridge English Corpus Consequently, no insecticides were applied specifically for the control of mealybugs prior to the 1970s. From theCambridge English Corpus None of the threemealybugspecies sustained mortality from disease during the current study. From theCambridge English Corpus These results suggest that the proportion of coding sequences in the genome of themealybugis smaller than in the fly. From theCambridge English Corpus The rejection of parasitized mealybugs during antennation was more frequent than during probing in both high and low egg-load conditions (fig. 3).
