The reproductive biology of flesh fly, Boettcherisca peregrina (Robineau-Desvoidy, 1830) (Diptera: Sarcophagidae)

The reproductive biology of the flesh fly, Boettcherisca peregrina (Diptera : Sarcophagidae ) was studied in the blowfly laboratory (25 -30ºC, 60 - 80% RH and 12 hrs light and 12 hrs dark) of the Institute of Food and Radiation Biology, Atomic Energy Research Establishment, Dhaka. The female reproductive system of B. peregrina comprises of two ovaries, two lateral oviducts, a common oviduct, three spermathecae, and a pair of accessory gland, a bilobed incubation pouch, vagina and genital opening. The male reproductive system B. peregrina consists of a pair of testes, a pair of vasa deferentia, a pair of accessory gland, a median ejaculatory duct, an ejaculatory sac and aedeagus. There is a general trend of gradual development of different organelles of the male and female reproductive systems from adult emergence to reproductive maturity. Protein diet was essential for proper development of female reproductive system. Oocyte development was apparent in both protein fed and protein unfed females. The mean sex-ratio of male to female was 20.2 : 14.2.

Male To Female

AbstractCalling by newly emerged female Lambdina fiscellaria lugubrosa (Hulst) began the first evening and commenced 15 h after the onset of light in nature and in a 14L:10D photoperiod regime in the laboratory. Copulation began 0.5 to 1.5 h later, and moths remained in copulation an average of 3.45 h. The internal reproductive system is typical of ditrysian-type Lepidoptera. Mating usually resulted in the transfer of a single, spheroid spermatophore with a long collum. The spermatophore was placed in the bursa copulatrix in such a position that spermatozoa could leave through the aperture into the ductus seminalis. The greatest mating success occurred between 2- to 4-day-old males and females up to 4 days old. Maximum oviposition occurred on the day after mating. Numbers of eggs maturing and being laid were increased after mating. Mean longevity of mated and unmated females in the laboratory was 18.1 and 20.8 days, respectively. Mating success was greatest at a 6:1 male to female sex ratio, and progressively less at a 1:1 and 1:6 sex ratio. Males mated only once in a 24-h period, but were capable of multiple mating. Females usually accepted one spermatophore but occasionally up to three were found.

Accessory Glands

In the male larva of Ctenicera aeripennis destructor (Brown), the reproductive system consists of paired mesodermal gonads situated in one of the second to fifth segments of the abdomen, an ectodermal genital capsule and paired mesodermal ampullae situated in the ninth segment of the abdomen, and a pair of mesodermal cell strands that connect the gonads to the ampullae. In the female larva, the reproductive system consists of paired mesodermal gonads situated similarly to those of the male, paired mesodermal ampullae situated at the posterior margin of the seventh segment, and a pair of mesodermal cell strands that connect the gonads to the ampullae. During the larval stage, prepupal period, and pupal stage, the gonads and cell strands of the male develop into testes and vasa deferentia, respectively, and those of the female, into ovaries and lateral oviducts, respectively. In the male, during the prepupal period and pupal stage, the ampullae develop into the paired spermatophoral and accessory glands and the seminal vesicles; the genital capsule develops into the ejaculatory duct and external genitalia. In the female, during the prepupal period and pupal stage, the ampullae develop into the common oviduct; the vagina forms from a groove in the ventral epidermis of the eighth and ninth abdominal segments; the uterus, spermatophoral receptacle, spermatheca, accessory gland, and its duct develop from invaginations in the vaginal groove in the eighth abdominal segment; the external genitalia develop from ridges on the sternal epidermis of the ninth abdominal segment.

Male To Female

The abdomen of the adult of the prairie grain wireworm, Ctenicera aeripennis destructor (Brown), consists of 10 segments, the posterior 3 of which are modified for reproduction in both sexes. Distinctive features of the male reproductive system are a pair of large spermatophoral glands that secrete the spermatophore, and a bilaterally symmetrical, trilobed phallic organ. Characteristics of the female reproductive system are egg tubes of the acrotrophic type, and a spermatophoral receptacle with a distinctively spinose intima.Neither the male nor the female mate more than once. The spermatophore, within which the seminal fluid is transferred from male to female, is slowly dissolved in the spermatophoral receptacle during the oviposition period and the gelatinous fluid is applied to the eggs as they are laid. This species does not reproduce parthenogenetically.

In both the male and female adult midge, the posterior three abdominal segments are modified for the reproductive function, and the musculature of these segments is modified accordingly. Main features of the male internal reproductive system are testes consisting of one sperm tube each, in which spermatogenesis is complete, and a glandular ejaculatory duct of four sections. The muscles of the posterior pregenital segments are modified for torsion. The muscles of the terminalia are described. Those of the ninth segment are greatly modified for the genital function. The female has numerous three-chambered polytrophic ovarioles extending radially from a common central egg passage in the ovary, and there is a single accessory gland. The muscles of the female terminalia are described. The reproductive system of several specimens parasitized by a nematode worm is discussed.

Physiological Dose

ABSTRACT The present investigation deals with the oestrogen-sensitivity of the female reproductive system during the neonatal period. Newborn female guinea pigs were used as test animals. At different times after a single subcutaneous injection of a physiological dose of 0.1 μg or an unphysiologically high dose of 10 μg 17β-oestradiol/100 g body weight, the RNA- and protein-synthesis was examined in the hypothalamic region, pituitary, cerebral cortex, liver, adrenal gland, ovary and uterus. With a physiological dose an increase in organ weight, protein content, RNA-and protein-synthesis was found only in the uterus. These alterations turned out to be dose-dependent. In addition to the findings in the uterus an inhibition of the aminoacid incorporation rate occurred in the liver following the injection of the high oestradiol dose. As early as 1 hour after the administration of 0.1 μg 17β-oestradiol an almost 100% increase in uterine protein synthesis was detectable. This result demonstrates a high oestrogen-sensitivity of this organ during the neonatal period. All the other organs of the female reproductive system such as the hypothalamus, pituitary and ovary did not show any oestrogen response. Therefore the functional immaturity of the uterus during post partem life is not the result of a deficient hormone sensitivity but is correlated with the absence of a sufficient hormonal stimulus at this time. The investigation on the effects of actinomycin resulted in different reactions in the uterus and liver. In contrast to the liver a paradoxical actinomycin effect was found in the uterus after treatment with actinomycin alone. This effect is characterized by a small inhibition of RNA-synthesis and a 50% increase in protein synthesis. The treatment of the newborn test animals with actinomycin and 17β-oestradiol together abolished the oestrogen-induced stimulation of the uterine RNA-and protein-synthesis. Consequently, the effect of oestrogens during the neonatal period is also connected with the formation of new proteins via an increased DNA-directed RNA-synthesis.
