Effects and tissue pathology of an unidentified microsporidium from the convergent lady beetle, Hippodamia convergens Guérin-Méneville (Coleoptera: Coccinellidae), on three non-target coccinellids

Saito, Taro (Halifax, N.S. : Saint Mary's University, 2008)

A microsporidium from H. convergens was transmitted horizontally to three non-target coccinellids (Adalia bipunctata L., Coccinella septempunctata L. and Harmonia axyridis Pallas) under laboratory ...
Effects of the microsporidian pathogen, Nosema adaliae on the seven-spotted lady beetle, Coccinella septempunctata L. (Coleoptera: Coccinellidae)

Elkabir, Entisar (Halifax, N.S. : Saint Mary's University, 2016)

Lady beetles play an important role in the regulation of aphids and other soft-bodied insects in nature. A noticeable decline in lady beetle populations in North America in recent years has become a significant cause for ...
Intraspecies transmission and effects of an unidentified microsporidium on the convergent lady beetle, Hippodamia convergens Guérin-Méneville (Coleoptera:Coccinellidae), used for biological control

Joudrey, Philip E. (Halifax, N.S. : Saint Mary's University, 2006)

Convergent lady beetles, Hippodamia convergens Guérin-Méneville, are often used for aphid control in agriculture and in home gardens. Beetles are collected from overwintering sites in California and are customarily released ...
Ultrastructure and tissue pathology of two microsporidia infecting the two-spotted lady beetle, Adalia bipunctata L. (Coleoptera: Coccinellidae) and the green lacewing Chrysoperla carnea Stephens (Neuroptera: Chrysopidae), used for biological control

Steele, Thomas Jean (Halifax, N.S. : Saint Mary's University, 2013)

Two undescribed microsporidia were found in insects that are commercially available for biological control: one from field-collected Adaliae bipunctata and another from Chrysoperla carnea purchased from a commercial ...
Ultrastructure of an unidentified microsporidium from the convergent lady beetle, Hippodamia convergens Guérin-Méneville

Le, Jeffrey (Halifax, N.S. : Saint Mary's University, 2009)

An unidentified microsporidium was found in adult Hippodamia convergens Guérin-Méneville that were obtained from a commercial insectary for aphid biological control. Ultrastructure of the microsporidium was examined by ...
