Estimativa de entropia de Muscina stabulans (Fallén) (Diptera, Muscidae) em condi??es artificiais
Krüger, Rodrigo Ferreira;Erthal, Simone Giehl;
Revista Brasileira de Entomologia , 2006, DOI: 10.1590/S0085-56262006000200009
Abstract: entropy estimation in muscina stabulans (fallén) (diptera, muscidae) under laboratory conditions. entropy (h) as a concept in demography was adapted from that of physics to quantify the impact of mortality on life expectancy and to quantitatively demonstrate mortality tendencies in experimental populations. entropy was estimated for 160 pairs of muscina stabulans (fallén, 1817) in a climate-controlled chamber (24.8oc ± 0.6oc, relative humidity 70 - 80%, 12 h photophase). both sexes had h values intermediate to those theoretically expected (0.0 - 0.5), showing that the survival curve is rectangular. the age-specific mortality distribution shows that mortality affects adults of this species in two ways. first, mortality is higher for 10 days from pupal emergence. second, mortality again increases between 20-30 days after emergence. small differences in mortality rates cause a greater overall impact on the survival of females.

Abstract: the development of muscina stabulans (diptera, muscidae) after exposure to metarhizium anisopliae (cg34 isolated) fungi under laboratory conditions was evaluated. suspensions of spores were prepared in concentrations of 105, 106, 107, and 108conidia/ml-1. ninety postfeeding larvae per treatment, divided into five treatments and three repetitions, were dived for one second in the respective suspensions, and transferred to petri dishes with humidified filter paper and maintained in bod at 25 oc with 80% relative humidity and a 12:12h photoperiod, until the emergency of adults. the rate of pupal mortality and the period of pupal development were evaluated. the larvae showed susceptibility to the action of m. anisopliae in different levels of concentration. the pupal mortality increased accordingly to the increase in the conidia concentration (from zero to 47%), as well as prolonged the time of development of the pupae (from 8.8 to 10 days). the application of m. anisopliae in this phase of the biological cycle compromised the development of m. stabulans and interfered in the natural control of pests that develop in the same environment.

Abstract: a study was conducted to investigate the thermal constant in an experimental population of muscina stabulans (fallén 1817). a natural population was obtained from a livestock and their f1 generations were maintained at four constant temperatures (16°c, 20°c, 26°c and 31°c). the thermal constant was calculated by the hyperbole method using the base temperature, tb = 4.4°c and the thermal constant k = 35.3 gd. ricker's geometric regression, considering tb = 7.8°c and k = 28.9 gd was also calculated.

Comportamento de propaga??o radial de larvas de Muscina stabulans (Fallén) (Diptera: Muscidae) em condi??es de laboratório

Neotropical Entomology , 2010, DOI: 10.1590/S1519-566X2010000200008
Abstract: muscina stabulans (fallén) is a synanthropic fly commonly found in decomposing animal matter. once food resources are exhausted, larvae will disperse in search for a suitable place to pupariate or for an additional source of food. the behavior of propagation of postfeeding l3 larvae was studied by analyzing the distance of propagation, the depth of pupariation site, the pupal weight and sex ratio using a 50 cm circular arena divided in four quadrants, and filled with a 10 cm thick layer of humid sawdust. the total of 70.9% of the larvae pupariate up to 20 cm away from the arena's center, with 41.8% of them from 2.1 cm to 4.0 cm deep. pupae that did not yield adults were lighter, and were originated by larvae that moved longer away and dug deeper to pupariate in relation to those from which adults emerged.
Intestinal myiasis caused by Muscina stabulans  [cached]

Indian Journal of Medical Microbiology , 2008,
Abstract: Intestinal maggots were isolated from a patient, who had reported to the Department of General Medicine of Sri Manakula Vinayagar Medical College, Puducherry, in southern India with complaints of abdominal distress, bloating of abdomen and intestinal hurry following a meal. He was diagnosed as a case of intestinal myiasis. Maggots obtained from his stool were identified to be Muscina stabulans based on characteristic patterns of posterior spiracles. He was treated with purgatives and albendazole. This intestinal myiasis case caused by M. stabulans is reported here because of its rare occurrence and the need to establish a correct diagnosis.

Ciência Rural , 2010, DOI: 10.1590/S0103-84782010000300030
Abstract: this is the first published report concerning reproduction and survival using life table analyses of fertility and survival for muscina stabulans maintained under laboratory conditions with artificial diets. the intrinsic rate of growth, reproduction rate and average generational time were obtained, suggesting a rapid population growth under these rearing conditions. these findings permitted the creation of time models of survival and oviposition, as well as a quantitative estimate of the adaptation capacity of this species.

Effect of the Non-steroidal Ecdysone Agonist, RH-5849, as a Control Agent Against the False Stable Fly, Muscina stabulans (Falle`n)  [PDF]

Abstract: The non-steroidal ecdysone agonist, RH-5849, was assessed as IGR against the false stable fly Muscina stabulans (Falle`n). A dose range of 0.025, 0.100, 0.400, .000 and 4.000 μg/insect was topically applied on 1 day old 3rd larval instar and the newly moulted pupae. The larval mortality was increased by increasing RH-5849 doses. While the pupal and adult mortalities which resulted from treated larvae were increased by decreasing doses. On the other hands, the higher of pupal deformation (40.3%) was obtained due to effect the dose of 1.000 μg/larva. Although some various deformities of the adult stage, there is no certain trend could be encountered for the adult deformities. No perfect adults could be emerging as affected by RH-5849 at the dose levels of 4.000 and 1.000 μg/larva. In case of treated pupae with RH-549 the percentage of pupal mortalities were increased by increasing the dose levels. Such relation could not determine completely for the adult mortalities or even the adult deformities. It is noteworthy to mention that, sex ratio of adults was encountered as two fold males than females after treating the newly moulted pupae with 1.000 μg /pupa. Some other data of sex ratio indicated the male predominance after treating the larvae with 0.025 or 0.100 μg/larva. RH-5849 was severely suppressed the reproductive performance of M. stabulans, particulary at the two higher doses of 1.000 and 4.000 g/larva or /pupa. Also the resulted deformed females were not lay eggs.
