C-banding, fluorescent staining and NOR location in holokinetic chromosomes of bugs of the Neotropical genus Antiteuchus (Heteroptera: Pentatomidae: Discocephalinae) [PDF]

open access: yes, 2006
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 diversity of feeding habits recorded for water boatmen (Heteroptera: Corixoidea) world-wide with implications for evaluating information on the diet of aquatic insects

open access: yesEuropean Journal of Entomology, 2017
Food webs are of crucial importance for understanding any ecosystem. The accuracy of food web and ecosystem models rests on the reliability of the information on the feeding habits of the species involved.

The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach

open access: yesInsect Molecular Biology, EarlyView.
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

open access: yesEuropean Journal of Entomology, 2003
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?

open access: yesJournal of Applied Entomology, EarlyView.
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]

open access: yesنامه انجمن حشره‌شناسی ایران, 2008
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
