Morphology and Histology of the Female Reproductive System of Abedus ovatus Stal (Belostomatidae: Hemiptera: Insecta)

Abstract

Morphological and histological studies on reproductive system of insects have called the attention of several investigators (Snodgrass 1935, Bonhag 1958, Davey 1965, Wigglesworth 1965 Bryan (1954)

Redescription of Megamelus scutellaris Berg (Hemiptera: Delphacidae), a Candidate for Biological Control of Water Hyacinth

“…1), a thinner proximal segment that expanded into a calyx where the pedicels attached and an enlarged distal portion that connected to the common oviduct. Megamelus scutellaris ovarian morphology was similar to other delphacid planthoppers (McMillian 1963;Mochida 1973;Szklarzewicz et al 2007) and other hemipteran species (Becker 1980;Lalitha et al 1997;Hummel et al 2006;Szklarzewicz et al 2007). …”

Morphology of the Female Reproductive System and Physiological Age-Grading of Megamelus scutellaris (Hemiptera: Delphacidae), a Biological Control Agent of Water Hyacinth

“…1), a thinner proximal segment that expanded into a calyx where the pedicels attached and an enlarged distal portion that connected to the common oviduct. Megamelus scutellaris ovarian morphology was similar to other delphacid planthoppers (McMillian 1963;Mochida 1973;Szklarzewicz et al 2007) and other hemipteran species (Becker 1980;Lalitha et al 1997;Hummel et al 2006;Szklarzewicz et al 2007).…”

Gross morphology and ultrastructure of the female reproductive system of Diaphorina citri (Hemiptera: Liviidae)

“…The basal location of the arrested oocytes in the trophic chamber of D. citri follows the common pattern described for telotrophic ovaries (BÜNING 1994, with only one oocyte developing per reproductive cycle. This reproductive strategy is also observed in Megoura viciae Buckton, 1876 (Homoptera: Aphididae) (BROUGH & DIXON 1989) and Adelges laricis Vallot, 1836 (Hemiptera: Adelgidae) (SZKLARZEWICZ et al 2000), and may be an adaptation to space or nutritional limitations, given that other insects have the capacity to produce several eggs per cycle (LALITHA et al 1997, SZKLARZEWICZ et al 2008, WINNICK et al 2009). …”

“…The number of ovarioles per ovary varies considerably among different taxa, ranging from a single ovariole in aphids (BÜNING 1985(BÜNING , 1994 to thousands in termite queens and coccids (BÜNING 1994, GILLOT 2005. Auchenorrhyncha may have from one to 15 ovarioles per ovary, whereas members of Heteroptera commonly have seven ovarioles per ovary (BÜNING 1994, LALITHA et al 1997, HODIN 2009. Plasticity in the number of ovarioles has been documented for aphids and scale insects in Sternorrhyncha, and the ovary of psyllids can contain up to 100 ovarioles (BÜNING 1994, HODIN 2009).…”

“…Plasticity in the number of ovarioles has been documented for aphids and scale insects in Sternorrhyncha, and the ovary of psyllids can contain up to 100 ovarioles (BÜNING 1994, HODIN 2009). The structure of the reproductive apparatus and the process of oogenesis in Heteroptera (Hemiptera) have been extensively studied (LALITHA et al 1997, CAPERUCCI & CAMARGO-MATHIAS 2006, but information for the remaining suborders is scarce (BUNING 1985, SZKLARZEWICZ et al 2008. In order to increase the overall knowledge on the reproductive system of sternorrhynchans, we characterized the morphology and ultrastructure of the female reproductive apparatus of Diaphorina citri Kuwayama, 1908 during oogenesis.…”
