Meiotic behavior and karyotypic variation in Acledra (Pentatomidae, Heteroptera)

Meiotic behavior and karyotypic variation in Acledra (Pentatomidae, Heteroptera).

Acledra comprises 15 taxonomically identified species, most of which are crop pests. This is the first cytogenetic study of species of this genus. Acledra kinbergii and A. modesta showed the modal number of the Pentatomidae (2n = 14 = 12 + XY), while A. bonariensis had a reduced complement (2n = 12 = 10 + XY), with a markedly larger autosomal pair. Meiotic behavior follows the general pattern o...

First report on meiotic behavior of chromosomes in three species of subfamily Pentatominae (Pentatomidae: Heteroptera).

Regardless of rich biodiversity, cytogenetic reports on Pentatomidae refer to less than 400 species. This paper reports, for the first time, course of meiosis of three species of subfamily Pentatominae viz., Tolumnia antennata Distant, Cahara jugatoria (Lethierry) and Cahara confusa (Distant). Species-specific variations observed with respect to association pattern of X and Y during prophase, a...

Biology and Reproductive Behavior of Murgantia histrionica (Heteroptera: Pentatomidae)

Life history parameters and reproductive behaviors of the harlequin bug, Murgantia histrionicaHahn (Heteroptera: Pentatomidae), were determined. Total developmental time from egg to adultwas 48d.After a sexualmaturationperiodof 7d, both sexesmated repeatedly,with females layingmultiple eggmasses of 12 eggs at intervals of 3 d. Adult females lived an average of 41 d,whereas adult males lived an ...

The Relationship between Dna Content and Alternative Meiotic Patterns in Certain Discocephalinids (pentatomidae; Heteroptera)

Mini Review: Karyotypic Survey in Triatominae Subfamily (Hemiptera, Heteroptera)

Triatomines are insects that are taxonomically included in the Hemiptera order and the Heteroptera suborder within the Reduviidae family and in the Triatominae subfamily [1]. These organisms are of great medical importance, because all of the species that belong to the Triatominae subfamily are both bloodsucking and susceptible to infection from the protozoan Trypanosoma cruzi Chagas, 1909 (Kin...
