Theses and Dissertations
The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama (Hemiptera: Liviidae), vectors “Candidatus Liberibacter spp.”, the causative agent of Citrus Greening Disease. Managing ACP is imperative given the continuous increase in HLB positive trees. An aspect of integrated pest management (IPM) is the use of entomopathogenic fungi for the biological control of D. citri.
In order to identify endemic entomopathogenic fungi actively infecting D. citri, ACP were collected from local residential areas, surface sterilized, and plated on a semi-selective agar medium. Collection of over 9,300 samples from 278 sites throughout the LRGV led to the positive identification of …

Aquatic Stage Mosquito Biocontrol: Effects Of Entomopathogenic Fungi Blastospores And Conidia On Aedes Aegypti Pupae, Ricardo Alberto Ramirez Garcia Rojas
Theses and Dissertations
Fungal entomopathogens present an opportunity to produce mosquito controls on-site, from remote locations to developing communities. Locally produced biopesticides have the potential to empower communities to develop internal disease vector control initiatives to protect local public health. We tested the effectiveness of the conidia solution and blastospore solution of Metarhizium anisopliae E9, Metarhizium anisopliae E1037, Isaria fumosorosea A97, and Isaria fumosorosea 9901 in controlling Aedes aegypti pupae. We observed that entomopathogenic fungi liquid blastospore solution induce mortality in Aedes aegypti pupae at a significantly greater rate than conidia solution and control treatment.
However, further analysis of testing methods used in …
