Pulse beetle, Callosobruchus chinensis is one of the major stored pests pulses. There were various factors that influence ovipositional behaviour C. chinensis. The preference host specificity for oviposition by female pest very important to lay maximum number eggs and also survival a species. Bigger size, smooth surface, deep coat coloured seeds are most suitable oviposition. combination temper...

Chrysomya albiceps specimens were derived from colonies kept under laboratory conditions. The oviposition period, total number of eggs-mass and the weight of the eggs-mass (average/female) presented significant differences between colonies regarding the sexual ratio of 1 male/1 female (situation 1), when compared to the other ratios (1 male/3 female, situation II), (1 male/5 female, situation I...

Oviposition and egg quality traits were studied in dwarf and naked neck layers in Maputo (Mozambique) during a 28-d period at 35 weeks of age. Birds were caged individually in a laying house with natural light and ventilation. Average daylight length during the study was 11.2 hr and minimum and maximum temperature was 19.6 °C and 30.1 °C, respectively. The main results show that the sex-linked ...

Bovine blood inoculated with bacteria isolated from screwworm [Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae)]-infested animal wounds was tested as an attractant for oviposition for gravid screwworms. Eight species of gram-negative coliform (Enterobacteriaceae) bacteria mixed with bovine blood singly or all species combined and incubated for various times produced volatiles that at...

Gravid females of 2 sand fly species, Phlebotomus papatasi and P. perniciosus, were exposed to carbon dioxide anesthesia for 5, 10 and 20 minutes. Recovery time, mortality at 0 min and 24 h, percentage of females laying eggs, time to oviposition, and egg productivity for each exposure time were registered. Survival, fecundity and oviposition time in the 2 species were not adversely affected by ...

BACKGROUND: Anopheles gambiae Giles is the most important vector of human malaria in sub-Saharan Africa. Knowledge of the factors that influence its daily oviposition pattern is crucial if field interventions targeting gravid females are to be successful. This laboratory study investigated the effect of oviposition substrate and time of blood feeding on daily oviposition patterns of An. gambiae...

the laelapid mite, gaeolaelapsaculeifer (canestrini) is widespread in soil habitats and feeds on different small arthropods, fungi and nematodes. the development and fecundity of g. aculeifer feeding on rhizoglyphus echinopus (fumouze & robin) as prey was studied at eight different constant temperatures which include: 16, 17.5, 20, 22.5, 25, 27.5, 30 and 32.5 ºc, with relative humidity of 6...

Flight and reproduction are usually considered as two life history traits that compete for resources in a migratory insect. The beet webworm, Loxostege sticticalis L., manages the costs of migratory flight and reproduction through a trade-off in timing of these two life history traits, where migratory behavior occurs during the preoviposition period. To gain insight into how migratory flight an...

This study examined the fecundity, oviposition, nymphal development and longevity of field-collected samples of the tropical bedbug, Cimex hemipterus (Fabricius) (Hemiptera: Cimicidae). Under environmental conditions of 26+/-2 degrees C, 70 +/- 5% relative humidity and a 12-h photoperiod, with bloodmeals provided by a human host, six strains of tropical bedbug had a fecundity of up to 50 eggs p...

the life history of an acarid mite, tyrophagus putrescentiae (schrank), on fusarium graminearum clade was investigated at 25 â± 1â°c, 60 â± 5% rh and a photoperiod of 16: 8 (l: d) h. incubation period for egg hatch, larval and nymphal periods and adult longevity were 2.22 â± 0.06, 3.46 â± 0.12, 4.84 â± 0.16 and 10.05 â± 0.9 days, respectively. the average life span of males and females were 22....
