“…The time needed for 150-200 individuals to enter the harvesting bottle was 10-12 min. In contrast, in the mass-production process of leafminers parasitoids, the time of harvesting was one of the main constraints; more than 50% of the time required for the production of Diglyphus begini (Ashmead) was devoted to the tedious task of aspirating adults into vials (Parrella et al 1989). Plants were successfully improved through nitrogen fertilization; it shortened significantly the larval and pupal stages of leafminer, suggesting that development responds rapidly to change in leaf nitrogen.…”

A method for mass rearing the parasitoid Neochrysocharis formosa (Westwood) was developed, using the leafminer Liriomyza huidobrensis (Blanchard) as insect host, and the Phaseolus vulgaris L. bean as host plant. About 1,500 parasitoids per tray of 84 plants emerged from about 2,000 leafminer larvae; 70% of these were females. The most suitable release density of host was two pairs of leafminer adults per bean plant, and that of parasitoid was three pairs per 24 leafminer larvae. Adult parasitoids were harvested based on positive photo-tactic response with 94.5% efficiency. Plants were improved by trimming their tips to increase the leaf area. The trimming process increased the number of leafminer larvae by about 32%. Furthermore, nitrogen fertilization of plants overcame the size reduction of the insects due to continuous rearing. Rearing of leafminer under light-dark (16:8 h) cycle decreased the development period of larvae and pupae. In addition, it restricted the time and duration of larval emergence and adult eclosion. Storage of parasitoid males and females at 7 and 10°C ± 0.5, respectively, proved to be optimal. The fertility of the massproduced parasitoids after 1 year of rearing reduced by about 23%, and the sex ratio shifted toward males. In conclusion, successful mass production of N. formosa was achieved through designing suitable rearing cage and an efficient harvesting device, improving the host plant, and determining the age and the conditions for cold storage of the parasitoid and its host. Next, we checked the characteristics of the massproduced wasps to ensure the efficacy when used in the field.

“…Pots were exposed to adults of Liriomyza in colony cages for oviposition which produced 357.4 ± 25.1 larvae/pot. Plants containing late 2 nd to early )'d instar larvae were exposed to D. begini adults in parasitoid colony cages for 24 h. The number of adult parasitoids emerging per pot was 99.7 ± 9.7, 47% of these were females (Parrella et al 1989).…”
