The control of Parlatoria pergandii (Comstock, 1881) was studied in citrus orchards at Belksiri (Gharb area), Morocco. Three concentrations Spirotetramat (T0 = 0 L/Ha, T1 0.625 T2 0.755 and T3 1 L/Ha) were applied to 4 ha Valencia late orchard (each dose for citrus). insecticidal evaluated on two stages larvae (L1 L2) P. three females, F1, F2, F3. Similarly, the rates parasitism by Aphytis hisp...

Abstract Citrus vein phloem degeneration (CVPD) is the Indonesian name for Asian form of devastating and incurable citrus disease known internationally as huánglóngbìng. It associated with a phloem-limited pathogen, ‘Candidatus Liberibacter asiaticus’ (CLas) transmitted by Asiatic psyllid (ACP), Diaphorina citri. ACP originated in South Asia but was first observed on 1900 Java to where it may h...

The biology and behaviour of the psyllid Diaphorina citri Kuwayama (Hemiptera: Sternorrhyncha: Liviidae), the major insect vector of bacteria associated with huanglongbing, have been extensively studied with respect to host preferences, thermal requirements, and responses to visual and chemical volatile stimuli. However, development of the psyllid in relation to the ontogeny of immature citrus ...

The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama, is the key pest of citrus wherever it occurs due to its role as vector of huanglongbing (HLB) also known as citrus greening disease. Insecticidal vector control is considered to be the primary strategy for HLB management and is typically intense owing to the severity of this disease. While this approach slows spread and also decreases s...
