Laboratory biology and rearing of leiophron uniformis hymenoptera braconidae a parasite of lygus spp hemiptera heteroptera miridae



Laboratory biology and rearing of leiophron uniformis hymenoptera braconidae a parasite of lygus spp hemiptera heteroptera miridae



Annals of the Entomological Society of America 74(3): 334-337



Leiophron uniformis (Gahan) attacked all 5 host (Lygus hesperus Knight) nymphal instars, successfully parasitizing instars 1-4. Time to parasite emergence increased when younger instars were attacked. Parasite larvae emerged from host instar 3 through adult. The most cocoons per female parasite were produced when host instars 2 or 3 were attacked. All host instars yielded similar numbers of female offspring per female parasite. No increase in offspring per female parent was found when nymphs were exposed for periods > 1 h. The most cocoons per female parasite were obtained when 75 hosts per parasite female were exposed. There was no increase in female offspring with more than 50 hosts per parasite female. A successful rearing procedure was developed with the aid of these data.
