Klambothrips myopori

Mound & Morris, 2007

Naio Thrips

Klambothrips myopori is a -forming in the , described by Mound and Morris in 2007. to Australia and New Zealand, it invaded California in 2005 and has since become established in Hawaii and the contiguous United States. The is obligately associated with Myoporum plants, inducing galls on foliage. It has emerged as a significant pest of ornamental plantings in California, with documented variation in host suitability across different Myoporum .

Identification

As a member of , this can be distinguished from other by the presence of an aptergite ( on the eighth abdominal ) and a tube-like abdominal segment. Species-level identification requires examination of antennal segmentation, , and male . Within Klambothrips, K. myopori is distinguished by its specific association with Myoporum plants and . Distinguishing it from congeneric species and other gall-forming thrips on Myoporum requires taxonomic examination.

Habitat

Associated with Myoporum shrubs and ground covers in urban and ornamental landscapes. In its invaded range, found in southern California where Myoporum laetum and such as 'Pacificum' are planted. suitability varies: successfully colonizes M. laetum and M. 'Pacificum', fails to complete development on M. 'Clean n Green' and M. 'Putah Creek'.

Distribution

to Australia and New Zealand. to North America: first detected in California in 2005. Established in Hawaii and the conterminous 48 United States. Predicted by CLIMEX modeling to have potential for establishment in many regions globally.

Diet

; feeds exclusively on Myoporum (Lamiales: Scrophulariaceae).

Host Associations

Myoporum laetum - primary Most suitable ; extensive damage observed
Myoporum 'Pacificum' - Suitable ; damage observed
Myoporum 'Clean n Green' - unsuitable Development failed in laboratory trials
Myoporum 'Putah Creek' - unsuitable Development failed in laboratory trials

Life Cycle

Development from to occurs between 15°C and 35.5°C. Temperature-dependent developmental rates have been modeled; the Briere-1 model best describes cumulative development. Specific durations and not documented in available sources.

Behavior

Induces on foliage. Exhibits host plant recognition , with demonstrated preference for certain Myoporum in laboratory and field trials. Second- appear most vulnerable to .

Ecological Role

; inducer. Serves as for a diverse complex in California, including from five and from five . Documented predators include Orius spp. (), Chrysoperla spp. (), , Franklinothrips orizabensis (), and Salticidae spiders.

Human Relevance

pest of ornamental Myoporum plantings in California. Causes extensive damage to susceptible , particularly M. laetum and M. 'Pacificum'. Subject to research; Orius insidiosus and Chrysoperla rufilabris identified as potential agents, with both displaying that suggest efficacy at low pest .

Similar Taxa

Other PhlaeothripidaeMay induce similar ; requires microscopic examination of morphological characters for differentiation
Other Klambothrips species may occur on related plants; boundaries require taxonomic assessment

More Details

Predator Functional Responses

Orius insidiosus displays a II to K. myopori, while Chrysoperla rufilabris displays both Type II and Type III responses depending on stage. Both consume more second- than other stages and consume higher proportions of prey at lower pest , suggesting optimal release timing early in the growing season when are low.

Invasive History

First recorded in California in 2005; subsequent spread to Hawaii and other parts of the contiguous United States. CLIMEX modeling predicts substantial global potential, though Maxent predictions differ.
