However, adult eclosion did not always occur from cocoons derived from hosts that had been parasitized at the later time points. Six days later the female was supplied with similar cocoons and with one not covered with strawboard. However, second and fourth instars were also readily attacked, together contributing almost 50% of the final number of parasitoid cocoons produced. Under natural conditions, most cocoons were found in the upper 1 cm of sand within a radius of 500 cm from the nest. The host larvae hatched, entered the apples, and when fully fed, emerged and made their cocoons. Therefore, a second set of parasitized cocoons was left intact until the seventh day after oviposition and then carefully opened. Parasitized cocoons were put into a climate chamber immediately after the female completed oviposition. The cocoons were transferred to ventilated plastic containers for adult emergence and mating. The cocoons were collected and placed in clean containers for adult emergence. On the other hand, the soil was less compressed in the frames than in the field, making access to host cocoons easier. Each generation, 150-200 cocoons were chosen at random from more than 1000 cocoons to produce adults for maintaining the culture. Parasitoid cocoons were weighed, the wasp development time calculated and adult emergence monitored. To make silk, the filaments from several cocoons are unwound and reeled together, resulting in fibres of extraordinary strength. All cocoons that formed from parasitized hosts were removed from the stems and kept separately in vials plugged with cotton wool. All individuals emerged from the same sample of cocoons. A third set of parasitized cocoons was left intact from the time of oviposition until emergence of adults. Protective silken cocoons around the pupae were not removed during exposure to the high temperatures because we wanted to simulate natural conditions for pupal exposure. When parasitism and infection were concurrent, parasitoid larval development was significantly faster in infected hosts, and cocoons were significantly heavier. Adults remain inside their cocoons in a dormant stage throughout the wintering period. On collection, the larvae were put in mailing tins, containing strips of corrugated cardboard, and there allowed to remake their cocoons. Production of silkworm cocoons was also running at less than half the 1933 level. To ascertain the host of this species, searches were made for the cocoons of the parasite in the cages concerned, some two months later. The short wet and dry seasons were characterized by a large number of cocoons hatching and a high proportion of immatures and juveniles in populations. Micro-dissecting scissors were used to open the cocoons to follow development of the pupae and prepupae. The exposed larvae were reared until parasitoid cocoons developed. Similarly, the parasitoids that developed in infected hosts also formed significantly larger cocoons. Afterwards, cocoons were checked daily until the host larvae were completely consumed. All larvae were removed twice a day and allowed to burrow into soil in plastic cylinders (1.3 l) where they formed cocoons. In laboratory observations, females did not show orientated movements towards host cocoons. Both cocoons were defective, and contained no larval skins. There was a preponderance of female fleas available during the first days of emergence from a batch of cocoons. Dead or diseased larvae, cocoons of parasitoids, predators and pupae were placed in empty 30 ml plastic vials, and sealed with the perforated lid. The purpose of covering the cocoons with sand grains is probably to escape detection and provide protection from enemies. Total no. of cocoons reared = 928. From the 9996 nymphs taken into rearing, 1464 parasitoid cocoons were collected, from which 1142 (78%) parasitoids emerged either in the same year of collection or following overwintering. However, as the time interval between infection and parasitism increased, parasitoid larval development was significantly extended by up to two days, and the cocoons formed were significantly (c. 20%) smaller. First, where the soil under the trees is cultivated, many larvae which have made cocoons in the soil, or in rubbish at the base of the tree, must be destroyed. Females continued to oviposit for 4-5 days, but the highest numbers of cocoons reared per female were obtained from those ovipositing within 48 h of mating. Any host larva that died before parasitoid larvae were able to emerge or form cocoons, escaped or were injured, were excluded from the calculation of developmental time. With respect to tree functional type, in all three regressions the cocoons on primary host trees were significantly higher than they were on non-hosts (table 3). In addition to determining expression levels in plants, this method was also used to detect the presence of the transgene in host larvae, parasitoid cocoons and adults. After an exposure period of about six weeks, cocoons were brought into the laboratory, washed out of the soil and kept under near field conditions in an insectary. The larvae construct silken cocoons, to which the soil adheres, usually below the surface of the soil but occasionally, in captivity, under dead leaves.
