    Coevolution? Insect/plant interactions have been important in defining models of coevolution and cospeciation. In the Canary Islands metapopulation structures combined with local variation in host plant ecology and habitat/island fragmentation may support Thompson’s ‘geographic mosaic theory of coevolution’ (Thompson ; Gomulkiewicz et al. ; Thompson & Cunningham . The leucaena psyllid (Heteropsylla cubana) causes defoliation and the death of leucaena. The insect is native to Central America, and has spread in the s across the Pacific to Asia, where it is now a serious pest and may spread to Africa. The biology of this pest is reviewed.

leucaena psyllid Native to Central America and Caribbean islands where the genus Leucaena occurs naturally. Leucaena (notably Leucaena leucocephala) has been used as an important agroforestry shrub throughout the tropics and subtropics and during the s and s the leucaena psyllid has rapidly followed this spread (Geiger and Gutierrez.

Psyllidae, the jumping plant lice or psyllids, are a family of small plant-feeding insects that tend to be very host-specific, i.e. each plant-louse species only feeds on one plant species (monophagous) or feeds on a few closely related plants (oligophagous). Together with aphids, phylloxerans, scale insects and whiteflies, they form the group called Sternorrhyncha, which is Class: Insecta.

The rapid spread of the leucaena psyllid, Heteropsylla cubana, across the Pacific Islands, Australia, southeast Asia and the Indian subcontinent durin the mids is legendary in the annals of modern economic entomolgy. The purpose of this sub-regional workshop was to bring together research scientists, forest pest management specialists and foresters from African.

Psyllid definition is - psylla. Recent Examples on the Web For the next 15 years, Baumann, Moran, and their colleagues used similar DNA analyses to document equally long-term relationships between bacteria and white flies, spittlebugs, cicadas, leafhoppers, and psyllids.

Six- and twelve-month results are reported from this trial in Hawaii, which is part of the International Leucaena Psyllid [Heteropsylla cubana] Trial Network established in by the NFTA.

Each trial had a standardized design in which trees were managed as hedgerows for fodder production (in order to maintain high psyllid populations).Cited by: Treatment for Psyllids.

Psyllid control information available online may recommend a wide range of chemical sprays, monitoring and beating of the bushes, but in practice, psyllids on most plants can be ignored so long as you put the broad-spectrum insecticides away and allow beneficial insects to feed in your garden.

Psyllids (Hemiptera: Psylloidea) are small insects that suck plant juices. The adults resemble miniature cicadas and are sometimes called jumping plantlice.

Over psyllid species occur on native or introduced landscape plants in California. Several psyllid species are pests of crops such as citrus, olive, pear, potato, and tomato.In Uganda, the productivity of leucaena has been drastically reduced by a psyllid. If left unpruned it will grow into a small to medium tree, but it it is often managed as a shrub.
