In these Lethocerus species, their chromosome numbers vary. Middle and hind legs distinctly banded see Figure 6below ; interocular space not over imdicus width of an eye; costal margin almost straight see Figure 7below and subparallel. Their body length can be up to 12 cm. The taste of the flight muscles is often compared to sweet scallops or shrimp. Sex chromosome evolution in cotton strainers of the genus Dysdercus Heteroptera: Male wingspot color Odonata. Only Editorial Filters by editorial images, which excludes images with model releases.

During mating season they fly from pond to pond or pool of water. The kinetochore of the Hemitera. All autosomes contained one indius two DAPI-bright bodies, while m-chromosomes showed relatively less brightly. Arrows indicate neo-XY chromsomes and arrowhead point to m-chromosomes. The remaining three Lethocerus species, L. Lethocerux Cytogenetics, Volume 3: In Heteroptera, chromosome polymorphism has been reported in some species.

These small, dark bugs, commonly found in tropical regions, range between 5 and 16 millimetres 0. Ventral view lethocerys the head of an adult Lethocerus sp. The presence of chromosome univalents and the behavior of chromosomes during spermatogenesis were also discussed.

Therefore, it was difficult to determine the exact locations of the nucleolar organizing regions on the chromosome. The females of some genera e. We gratefully thank Dr.

Ripple communication in aquatic and semiaquatic insects. Paratergites distinctly separated from the sternites. It is impossible to prove this possibility, because the previous one was studied long time ago. One was always associated with the neo-XY chromosome, and the other one could be located either close or far from the chromatin Figure 2e.

Lethocerus indicus, a giant water bug on hand. Ibdicus by the open source Biodiversity Informatics Platform.

The cytogenetics of Heteropteran insects are interesting primarily because they possess holocentric chromosomes. However, the chromosomal behavior during spermatogenesis of the Lethocerus species has not been described, except the chromosome formula, because the cytogenetics of most species were studied during andand the original papers are difficult to access Papeschi and Bidau ; Papeschi and Bressa Instead, the occurrence of m-chromosome univalents was the result of desynapsis, not of asynapsis Nokkala and Nokkala The origin of univalent chromosomes is the result of homologous chromosomes asynapsis or desynapsis White Green Papaya Salad and Lethocerus indicus with lettuce, long-beans, roasted peanuts, tomatoes in white plate and cool water.

Univalent chromosomes In the testis of an individual male, four cell types, designated A, B, Pethocerus and D, with different patterns of chromosome univalents were observed. Lethocerus indicus isolated on white background.

Lethocerus indicus on white background, giant water bug in Thailand. Bill Length Birds cm. The appearance of an m-chromosome bivalent indicated that m-chromosomes behaved like other autosomes undergoing synapsis in prophase I to form a bivalent. Nomenclature and Classification Nomenclature and Classification.

Belostomatidaea native species of Southeast Asia, is one of the largest insects belonging to suborder Heteroptera. Views Read Edit View history. Moreover, some families also possess a pair of m-chromosomes, which are also achiasmatic.

Meiotic sister chromatid cohesion in holocentric sex chromosomes of three heteropteran species is maintained in absence of axial elements. In the other sex chromosome, two big, bright bodies were located close to the middle, and the small one was next to one of the big bodies Figure 1a. Social interactions involving the costs and benefits of parental care characteristics of Heteroptera In heteropteran. Because they are attracted to light these insects are sometimes called electric-light bugs.
