"Biology of the invasive shell lerp psyllid, Spondyliaspis cf. plicatuloides (Froggatt) (Hemiptera: Aphalaridae)"

Spondyliaspis cf. plicatuloides (Froggatt) (Hemiptera: Aphalaridae) is native to Australia but was first detected outside its range in 2014, South Africa. It feeds on eucalypt species and thus has the potential become a pest commercial Eucalyptus plantations. Information basic biology of this insect, which important for development surveillance management strategies, lacking. To investigate life cycle general S. plicatuloides, psyllid reared under controlled glasshouse conditions potted red-flowering gum, Corymbia ficifolia. The egg incubation period, number nymphal instars their developmental time, adult fecundity, longevity duration were determined. major diagnostic features used differentiate five antennal segments, wing pad body length. Females reached reproductive maturity 2.3 ± 0.47 (mean SD) days after eclosion laid 16.2 3.9 eggs average. Reproduction sexual. instar took 10.7 1.2 hatch from egg. completed 22.6 1.4 brown scalloped shelters they secrete. insect's total lasted 37.37 1.17 death. Males females lifespan also reported. study provides information that will be useful future studies strategies.
