Rhyzobius lophanthae Behavior is Influenced by Cycad Plant Age, Providing Odor Samples in a Y-tube Olfactometer [PDF]
Insects, 2018 The scale predator Rhyzobius lophanthae Blaisdell was introduced to Guam and Rota to control invasive Aulacaspis yasumatsui Takagi armored scale infestations on the native Cycas micronesica K.D. Hill populations.

Forests, 2023 The natural distribution of Cycas micronesica includes three island groups. Damage to the widespread tree from the armored scale Aulacaspis yasumatsui was initiated with the 2003 invasion of Guam and the 2007 invasion of Rota. This herbivore has threatened the unique gymnosperm species with extinction.

Three invasive insects alter Cycas micronesica leaf chemistry and predict changes in biogeochemical cycling [PDF]
Communicative & Integrative Biology, 2016 Leaf litter chemical traits were measured for Cycas micronesica plants in Guam following leaf herbivory by the scale Aulacaspis yasumatsui, the butterfly Chilades pandava caterpillar, or the leaf miner Erechthias sp. to determine the influence of the non-

Host specificity of parasitoids (Encyrtidae) toward armored scale insects (Diaspididae): Untangling the effect of cryptic species on quantitative food webs. [PDF]
Ecol Evol, 2018 A high degree of cryptic species in host–parasitoid systems refines the true network structure and may cause us overestimating the stability of these interaction webs. Abstract Host specificity of parasitoids may be measured by various specialization indices to assess the variation of interaction strength among species and the structure of the wider ...

Temperature-dependent demography of Aulacaspis yasumatsui (Hemiptera: Diaspididae).
Journal of economic entomology, 2012 Aulacaspis yasumatsui Takagi continues to threaten the extinction of the endemic and endangered Cycas taitungensis (Shen et al.) in Taiwan. Failure to understand its population demographic parameters in detail will continue to hinder the success of pest management practices.

The Florida Entomologist, 1999 Observations were conducted in southern Florida on Aulacaspis yasumatsui Takagi (Hemiptera: Sternorrhyncha: Diaspididae), a recently introduced armored scale insect native to Southeast Asia. The insect's host plants, exclusively cycads, were identified in the following genera: Cycas (Cycadaceae); Dioon, Encephalartos, Microcycas, (Zamiaceae), and ...
