Mallada basalis (Walker) has the potential to be a valuable biological control agent because of its predatory abilities, strong reproductive capacity, and broad prey range. This study aimed to improve on a previously used artificial diet for M. basalis, to achieve a longer oviposition period and greater survival rate and fecundity. We analyzed the development, survival, longevity, and reproduct...

Phytoseiid mites are important for biological control of some pest species including phytophagous and small insects. The species, Phytoseius corniger Wainstein is one the most abundant predatory mite in fruit orchards urban green spaces Razavi Khorasan province, Iran. Biological parameters this feeding on two-spotted spider Tetranychus urticae Koch was studied first time under laboratory condit...

We investigated effects of temperature, at 70% RH, on the reproductive parameters of the parthenogenetic psocid Lepinotus reticulatus Enderlein (Psocoptera: Trogiidae). The lowest fecundity (21) was at 35 degrees C and the highest (41) at 27.5 degrees C. At 22.5, 25, and 27.5 degrees C, peak oviposition rates (eggs/female/week) occurred in week 3 and were 4.7, 6.6, and 7.8, respectively; also 5...

1. Plant defence of Viburnum shrubs against oviposition by its specialist herbivore, the viburnum leaf beetle [VLB Pyrrhalta viburni(Paykull)], involves an egg-crushing wound response in twigs. Although the response is variable among Viburnum species, it can have a strong impact on egg survivorship. Beetles typically aggregate egg masses with conspecifics along infested twigs, forming clusters ...

The mating behaviour and egg laying pattern of the areca nut white grub, Leucopholis lepidophora, were studied in Shivamogga district’s Hosanagara taluk. Females active between 18:40 19:20 hrs, when light intensity dropped to 83.62 lux. most males approached virgin female at 18:50 hrs (15.94 lux) session ended (0.26 lux). typical L. lepidophora was investigated. Female beetles began abdominal e...

Pre-larvae hatching fecundity and ovarian of narrow-clawed crayfish populations were estimated in the lakes reservoirs Belarus. Statistically significant differences females from various water bodies noted only for Lake Kichino. For all other bodies, dependence on length did not differ statistically was described by one equation. The greatest loss eggs during spawning period (oviposition), inse...

Schistosoma mansoni infection induces in their hosts a marked and sustained eosinophilia, which is influenced or modulated by complex mechanisms, that vary according to the phase of infection. To address this phenomenon, we used the air pouch (AP) model in control and infected Swiss webster mice, analyzing the cellular, tissue response and local expression of adhesion molecules [CD18 (beta(2)-c...

Physogastric queens of Melipona marginata were removed from their colonies in order to verify the acceptance of a new queen by workers. Colony strength was evaluated according to queen oviposition rate and comb diameters. Replacement was observed seven times. Its occurrence and speed related positively to colony strength, independently of queen's age. In weak colonies, queen replacement was obs...

This study was carried out to determine the effect of pre-incubation storage periods on egg weight loss, embryonic development and hatchability of hatching pullet eggs. Three hundred eggs were used for this experiment. The eggs were sourced on five different days (sixty eggs per day) at three days interval (day 0, 3, 6, 9, and 12) and weighed. The sixty (60) eggs collected on each day were subd...

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...
