Dr. J. E. McPherson, Educator and Researcher Extraordinaire: Biographical Sketch and List of Publications [PDF]
(excerpt) Like many outstanding naturalists, John E. (“Jay”) McPherson grew up with a strong interest in the natural world, especially insects. This innate curiosity led him to enroll as a zoology major at San Diego State University in 1959.

C-banding, fluorescent staining and NOR location in holokinetic chromosomes of bugs of the Neotropical genus Antiteuchus (Heteroptera: Pentatomidae: Discocephalinae) [PDF]
Different cytogenetic techniques including C-banding, base-specific fluorochromes and silver nitrate staining were used to compare the karyotypes of three species of bugs, representatives of the Neotropical genus Antiteuchus, namely A.

The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach
Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce

Pedicellar structures in Reduviidae (Heteroptera) - comments on cave organ and trichobothria
Sensillar structures of the antennal pedicel are investigated in Reduviidae and Pachynomidae. The cave organ, a presumably chemoreceptive structure, previously reported only for haematophagous Triatominae, is described here also for representatives of ...

What Are the Phylogenetic Limits to Pollinator Diversity?
ABSTRACT Although huge progress has been made over the past 200 years in identifying the diversity of pollinators of angiosperms and other plants, new discoveries continue to be made each year, especially in tropical areas and in the fossil record. In this perspective article I address the following questions: Just how diverse are the pollinators and ...

Comparison of development time and reproduction of typical and melanic Eurygaster integriceps (Heteroptera: Scutelleridae) under laboratory conditions [PDF]
Among the sunn pest populations, melanic phenotype of Eurygaster integriceps Puton is a distinct colour morph. A set of experiments were performed to examine possible differences between typical and melanic phenotypes of E. integriceps using overwintered
