A taxonomic reassessment of the triozid genusBactericera(Hemiptera: Psylloidea)

Abstract

Problem Statement: Psyllids as a small group of insects with plant feeding adult and nymphal stages, not only could have direct feeding damages but they could also transmit plant diseases especially viruses. Bactericera tremblayi had recently increased to high densities in onion fields in East Azarbaijan province in Iran and the pest had become widespread. This was the first study of the biology of the pest in Iran and probably in the world. Approach: After collection of the adult insects from infested onion fields, they were then reared in laboratory under controlled conditions (at 21±3°C, 60±10% RH and under a 14:10 (L: D) light regime) and different life stages of the pest were studied. Results: The lifespan of adult male and female psyllids was 33.63±2.36 and 39.94±2.64 days respectively. The preoviposition period was 3.75±0.14 days. The total number of eggs laid per female was 625.5±53.9. Egg incubation took 7.44±0.15 days and a mean of 90.3% eggs hatched. The nymphs passed through five instars before reaching the adult stage and the development time for the nymphal stage was 17.71±0.61 days. The sex ratio was estimated as 1:1. Conclusions: The results of the present study could successfully be applied to future IPM strategies in order to effectively control this pest with relatively unknown biological characteristics and decrease the damages observed in onion fields.

Biological properties of the endemic and threatened shrub in Iberia Vella pseudocytisus subsp. paui Gómez Campo (Cruciferae) and implications for its conservation

“…A sucking specialist triozid psilid in the genus Bactericera has been recently described from the taxon, B. vellae by Burckhardt and Lauterer (1997). The most similar taxon to this psilid is B. polygoni from Tadzhikistan (Burckhardt & Lauterer 1997).…”

Other Hemiptera Sternorrhyncha (Aleyrodidae, Phylloxeroidea, and Psylloidea) and Hemiptera Auchenorrhyncha. Chapter 9.4

“…Psylloids associated with such host-plants, have become established outside their native range and are sometimes responsible for severe damage to such plantations (Burckhardt and Elgueta 2000). One such psylloid is Blastopsylla occidentalis described from Australia, New Zealand and California, and subsequently reported from Mexico, Brazil and Chile (Burckhardt and Lauterer 1997). Th e species was recently reported in Italy (Laudonia 2006) and most likely this psylloid is already established in other Mediterranean countries.…”

The jumping plant-lice (Hemiptera: Psylloidea) of the Tatra National Park

“…With only some 2500 species, the jumping plant lice are not a very numerous group of insects (BURCKHARDT & LAUTERER 1997). They are found all over the world.…”
