Gene Expression in the Salivary Gland of Rhipicephalus (Boophilus) microplus Fed on Tick-Susceptible and Tick-Resistant Hosts

Frontiers in Cellular and Infection Microbiology, 2020
The success of cattle tick fixation largely depends on the secretion of substances that alter the immune response of the host. The majority of these substances are expressed by the parasite salivary gland and secreted in tick saliva.

Functional and Immunological Relevance of Anaplasma marginale Major Surface Protein 1a Sequence and Structural Analysis. [PDF]

, 2013
Bovine anaplasmosis is caused by cattle infection with the tick-borne bacterium, Anaplasma marginale. The major surface protein 1a (MSP1a) has been used as a genetic marker for identifying A.

Morphology of the Preimaginal Stages of Lasioptera donacis Coutin (Diptera: Cecidomyiidae), a Candidate Biocontrol Agent for Giant Arundo Cane

Psyche: A Journal of Entomology, 2015
The larval stages of Lasioptera donacis Coutin consist of three instars which develop within the mesophyll of the leaf sheaths of Arundo donax (L.) (Poaceae). The larvae feed aggregatively on mycelia of an ambrosia fungus.
