Foreword The Insect Pest Control sub-programme of the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture has worked for many years on developing the sterile insect technique (SIT) for tsetse fly control. A standard rearing system was developed twenty years ago that allowed the rearing of sufficient flies for research, development and small field operations, such as the BICOT ...

The effects of light rearing regimen on distal retinal development and photoreceptor ultrastructure were investigated using light and electron microscopy. Zebrafish larvae were reared in constant light, control/cyclic light (14 hr light/10 hr dark), or constant dark conditions until 4 or 8 days postfertilization (dpf). Gross retinal morphology was not altered by light rearing conditions; howeve...

The West Indian sweetpotato weevil Euscepes postfasciatus (Fairmaire) (Coleoptera: Curculionidae) is a major pest of sweetpotato Ipomoea batatas (L.) Lam (Solanales: Convolvulaceae) in some countries. In order to improve mass-rearing for an eradication program employing the sterile insect technique (SIT), optimal population density of E. postfasciatus in an artificial diet was examined. Six pop...

Permanent effects of early postnatal nutrition on the development and function of tissues and organs have been previously demonstrated primarily in humans and rodents. The objective of this study in calves was to analyze the impact of rearing conditions during the first 3 wk of life on morphology of insulin-producing pancreatic β-cells. Forty-two male Holstein calves were raised during the firs...

   Stability of bacterial flora in fish intestine is very important, because the intestine is an important organ for outbreak of microbial infections and other fish diseases especially when the fish have not been vaccinated. The aim of this study was to determine the bacterial flora of intestine in sturgeon juvenile in earthen ponds. The results can be applied to prevent the diseases occurren...

The Role of Child-Rearing Practices in the Socialization Processes of Junior High School Students: A Socio-Cultural Perspective M. Hossaynnejaad H. Abdollaahzaadeh, Ph.D. From a Vygotskian perspective since children construct their value systems through interaction with others, they can become self-regulated if their culture emphasizes such a characteristic via the child-reari...

This study examines the consequences of relaxing birth quotas by exploiting an exogenous two-child policy adopted local Chinese governments on different dates. Using China’s 2015 population census combined with a difference-in-differences framework, we find that adoption substantially increases number second-child births. The impact is more pronounced among couples who have higher fertility pre...

Mass rearing methods on artificial diets and cruciferous seedlings for the diamondback moth, Plutella xylostella L, are reviewed and described briefly.

The purpose of the present study was to examine the effects of the phenylalkylamine class of the L-type voltage-dependent calcium channel antagonist, verapamil (1.0, 2.5, 5.0, or 10 mg/kg i.p.), administered immediately after the acquisition task, on memory consolidation of the open field habituation task, in male Wistar rats. On the 48 h retested trial, all tested parameters (ambulation in the...

The objective of this study was to evaluate the effects of three alternative (ALT) rearing systems for growing pigs (outdoor: 150 m2/pig; straw bedding: 1.30 m2/pig; and hut with access to a courtyard: 1.30 m2/pig) compared with a conventional system (fully slatted floor: 0.65 m2/pig, considered as control), on pre-slaughter stress indicators in relation with meat quality. To that end, the numb...
