Study about Trioza erytreae: An Approach to Feeding and Oviposition Preference on Conventional Citrus Rootstocks | Chapter 4 | New Visions in Biological Science Vol. 8

 The Mediterranean Basin is the world's second-largest citrus-producing region, with Spain as the leading producer. Huanglongbing (HLB) is the most common and deadly citrus disease in the world, with three bacteria species belonging to the Candidatus Liberibacter genus as the causative agents. Diaphorina citri and Trioza erytreae, two psyllid vectors, are the major vectors for these infections.

T. erytreae is a pest of the Rutaceae family of plants, which includes cultivated citrus. This bug has lately been discovered in nations around the Mediterranean Basin, particularly in Spain and Portugal. The threat of HLB development has heightened concerns in the citrus-growing regions of Spain and Portugal, necessitating a performance study of T. erytreae on conventional citrus rootstocks as a strategy of lowering the bug population. T. erytreae survival, development, oviposition, and feeding preferences in non-grafted conventional citrus rootstocks were investigated in this study.

The preference of T. erytreae in potted plants of several standard citrus rootstocks is investigated in this study. Carrizo citrange, Citrus macrophylla, Citrus macrophylla, Citrus macrophylla, Citrus macrophylla, Citrus macrophylla, Citrus macrophylla, Citrus macrophylla, Citrus macrophylla, Citrus macrophylla, Citrus macrophylla, Citrus macrophylla, Citrus macrophylla, Citrus macrophylla, Citrus macrophylla, Citrus macrophylla, Citrus macro The feeding preference of T. erytreae adults for different rootstocks, as well as oviposition and survival of T. erytreae adults on various citrus materials, were used to assess the psyllid's behaviour and survival. T. erytreae had a strong preference for C. macrophylla as a host and food source, while Carrizo citrange was the best rootstock for insect reproduction and survival, followed by C. macrophylla. P. trifoliata, on the other hand, was the least appealing rootstock to T. erytreae adults, resulting in significantly decreased T. erytreae survival. Our findings show that traditional citrus rootstocks like Carrizo citrange and C. macrophylla may help to boost T. erytreae populations.
