African citrus psyllid or the two-spotted citrus psyllid (the latter name is in reference to a pair of spots on the base of the abdomen in late stage nymphs). These two psyllids are the only known vectors of the etiologic agent of citrus greening disease (Huanglongbing), and are the only eco- nomically important psyllid species on citrus in the world. Six other species of Diaphorina are reported on citrus, but these are non-vector species of relatively little importance (Halbert and Manjunath 2004). -

Pear Sawfly Caliroa Cerasi Order Hymenoptera, Family Tenthredinidae; Common Sawflies Introduced Pest
Pests of Trees and Shrubs Pear sawfly Caliroa cerasi Order Hymenoptera, Family Tenthredinidae; common sawflies Introduced pest Host plants: Cherry, cotoneaster, hawthorn, mountain- ash, pear and plum Description: Adult sawflies are 5–8 mm long, black and yellow, and stout bodied. Larvae are slimy, slug-like, and shiny olive-green to blackish in color. They are 12 mm long when full grown. Life history: Adults emerge early in June and lay single eggs on leaf undersides. Larvae appear in June, feed for about a month, then drop to the soil to pupate. A second generation can begin in early August. Overwintering: Prepupae in the soil. Damage symptoms: Larvae feed on upper leaf surfaces, Scorched leaves caused by pear sawfly larva defoliation leaving only the leaf veins. Heavy defoliation gives the damage.

Acquisition of Las by D. citri appears to be variable, and this variability may be due to the suitability of the host plants and their tissues for acquisition. Therefore, this study aimed to determine the effect of symptom severity of the disease on the feeding behaviour of D. citri. Use of an electrical penetration graph showed that the pathway phase of D. citri consisted of four waveforms, A, B, C, and D; wave- forms A and B have not been reported for D. citri before. The remaining waveforms, E1, E2, and G, conform to those described before for D. citri. The duration of the non-penetration period did not differ between healthy or infected plants. However, in moderately and severely symptomatic plants, the duration of the pathway phase increased, whereas the phloem phase was shorter. -
