This study compared the effects of fresh and decomposed liver on aspects of reproduction of the blowfly, Chrysomya chloropyga to determine the possibility of multiple generations of the blowfly on a single cadaver. The total development time from egg to adult were 8.75 and 8.50 days in the flies fed on fresh and decomposed liver respectively and we...

First, second and third instar larvae of the blowfly, Chysomya chloropyga collected from laboratory stock were exposed to a mixture of ground rice and fish supplemented with 1, 2, 3, 4, 6 and 10 % concentrations of neem seed (NS) and neem seed kernel(NSK) powders respectively. Twenty pairs of laboratory-reared adult males and females were also main...

The study investigated the growth patterns, sex ratios, mean condition factor and proximate composition of the body fluid of male and female blue crab, Callinectes amnicola from tropical marine habitat. This is with a view to providing information for effective management of C. amnicola as a fish resource. One hundred and ninety-five (195) crabs we...

Objective: To determine the specific effect of leaf powder of Harungana madagascariensis (H. madagascariensis), Margaritaria discoidea (M. discoidea), and Antigonon leptopus (A. leptopus) on the life cycle of Musca domestica (M. domestica). Methods: We tested the effects of the powder extracts of H. madagascariensis, M. discoidea, and A. leptopus o...

In this study, the interrelationships between various morphometric characters, viz., carapace width and length and chelae propodus length in males, as well as carapace width and length and abdominal width and length in females, were estimated using a total of 97 freshwater crabs (Sudanonautes aubryi). The allometric relationships between the charac...

The direct effects of Petiveria alliacea, and Flueggae virosa were tested on the life cycle of Musca domestica. Leaf powders of P. alliacea, and F. virosa at various concentrations of 2, 5, 10, and 15 % (w/w) were added to the mixture of rice and fish paste and tested on the larval duration, pupation percent, pupal weight, pupal duration, and adult...

The effects of starvation, feeding, sex and oviposition on the longevity of adult Zonocerus variegates L. in isolation or in groups was investigated in the laboratory. Females lived significantly longer than males either in isolation or in groups during feeding and to some extent in starvation. Females in groups with a male-biased sex ratio lived s...

Pulver parts of 15 Nigerian plants were used to determine survival, oviposition and emergence of adult blowfly, Chrysomya chloropyga, in laboratory. Eight of the plant materials were incorporated individually into the diet at 5% concentration of extract and used for survival studies while all the 15 plants were used to determine oviposition. Differ...

Spermathecal secretion of the female Atractomorpha lata Motschulsky consists of variable prominent protein fractions ranging from 31 to 75 kD in 0 day-old females and from 30 to 140 kD in day 10 to 50 fernales. The number of prominent fractions in mated fernales at 20, 40, and 50 day-old were more than those of the unmated females of the same age....

Copulation and post-copulatory mounting behaviors of Atractomorpha lata MOTSCHULSKY were observed and described under laboratory conditions. Copulatory behavior was initiated by a male approaching a stationary or feeding female without any courtship behavior. Pair formation involved mounting of the female without genital contact followed by a brief...

Mla accessory glands of Zonocerus variegatus L. undergo no significant changes in size after emergence. However, their protein content nearly doubles during thesecond week, and again during the fifth week, after emergence. Copulation has little effect on the protein content

The free amino acids of the accessory glands of adult male variegated grasshopper, Zonocerus variegatus (Linnaeus) were investigated at five different ages after emergence of insects maintained oh cassava Manihot esculenta, Cranz using automatic amino acid analyser, Beckman 121 MB. Thirteen amino acid components were consistently detected from days...
