Larvae of Cucujus clavipes (Fabricius) and Dendroides canadensis (Latreille) are frequently found under bark of decaying hardwood logs and those of Pytho depressus (Linnaeus) under that of dead conifers, especially pine (Pinus spp.) (Anderson and Nilssen 1978). Larvae of all three species have a dorsoventrally depressed, orthosomatic body and are well adapted for activity in the cambial layer. In dead trees, this area contains partially decomposed wood and bark resulting from the activity of phytophagous insects and other small invertebrates. According to textbooks of general entomology and other entomological literature, species within the genera Cucujus, Dendroides, and Pytho are predacious on other insects found in the cambial layer (Arnett 1968; Borrer et al. 1976; Borror and White 1970; Essig 1926; Peterson 1951; Swan and Papp 1972). However, no specific references to original studies demonstrating this type of feeding behaviour could be found. The purpose of this study was to determine the type of food consumed by larvae of these species and to determine if the structure of their mandibles and other mouthparts were indicative of such food consumption.

Food consumption survey is an essential parts of nutrition surveys. It helps to determine the type and quantity of food consumed, assessing the balance of the diet, the relationship between nutrient intake and health, diseases, and economic status, culture society... There are many methods to investigate food consumption. 24-hour food record is a method that record all food consumed by the subject during previous 24 hours. Using this method in chidren helps to assess the their diet to see if it responses the demand in order to have proper nutrition. Objectives: 1. Calculating the number of each food groups consumed within 24 hours of children 1 to 5 years in Phuoc Vinh ward, Hue City; 2. Assessing the quality of their diet and some related factors. Methodology: A cross-sectional study was implemented on 200 pairs of children aged 1 to 5 and parents or caregivers living in Phuoc Vinh ward, Hue city and some related factors. Results: 82% of the children’s diets covered 4 food groups. Prevalence of glucide, protein, lipide out of the total energy intake were 44.1%, 19.5%, 36.3% respectively within group of 12-<48 months and 50%, 19.5%, 30.6% respectively within group of 48-<72 months. Total energy and protein intake were higher than demanded (p <0.05) while glucide and lipide were lower than demanded (p <0.05). Economical status of family was significant associated with variety of food (all 4 food groups) in the diet of children (p <0.05) and total energy consumed (p <0.05). Conclusion: The children did not have proper nutrition so further research need to be implemented to have suitable interventions. Key words: 24 hours food records, children aged 1 to 5, Hue city.

Feeding habits of Stellifer rastrifer (Perciformes, Sciaenidae) at Guaratuba mangrove, Parana, Brazil, were studied from February 1996 to February 1997. It was observed that its diet was based on invertebrates, mainly Decapoda non-Brachyura and Polychaeta. In a smaller proportion there were plants, Copepoda, Gammaridea and Mollusca. The level of contribution of each food item changed according to the season and the individual size. Such plasticity in feeding behaviour was similar to that described to some fish populations from other estuaries, and could be an indicator of the high level of instability presented by this kind of ecosystem.

Recently computerised pig feeding has attracted interest from pig breeding companies, to improve selection. Testing has in the past been carried out on Individually housed pigs, whereas on commercial farms pigs are group housed and correlations between these two environments can be poor. Practically this problem can be solved by group housing pigs with an electronic feeding station. This system allows one pig to feed at a time and records each pigs Identity and the amount of food consumed, making the selection environment similar to conditions found on commercial farms. This paper presents results showing the strong effect of social factors on the feeding behaviour of Individual growing pigs In such a system.The subjects were 30 male and 30 female Large White X Landrace pigs (Cotswold Pig Development Co. Ltd, Lincoln UK), divided Into six groups of ten, balanced for sex and initially body weight (mean starting and finishing weight 32.1 vs 68.5kg) within a pen but not between pens. Measurements of feeding behaviour (see below) were continuously monitored for an average of 38 days, by one electronic feeding station (Feed Intake Recording Equipment, developed by Hunday Electronics Ltd.) In each pen. The pigs were fed on a standard pelleted grower diet.

The rate of 22Na turnover was measured in 4 captive emus each fed on 3 diets. There was a close relationship between 22Na turnover and the intake of dietary sodium (r = 0.92), DM (r = 0.93), gross energy and metabolizable energy (r = 0.94). DM intake, estimated from 22Na turnover, accounted for 89% of the variation in actual DM intake, and suggested that 22Na turnover could provide a reliable method for estimating food consumption by populations of free-living emus. However, estimates of food consumed by individual animals may not be reliable.

The article is devoted to the assessment of food consumption in the region. The aim of the study is to develop the main directions of improving the food security of Kyrgyzstan in the future. It is revealed that the absolute number of the world population suffering from malnutrition, according to modern estimates, increased from about 804 million in 2016 to almost 821 million in 2017. This trend serves as a clear warning that, if not intensified efforts, the task of the SDGs to eliminate hunger by 2030 will not be achieved The research toolkit includes mathematical methods for processing statistical data, an assessment of the energy and nutritional value of food consumed by the population. The scientific novelty of the study is to identify the factors that limit food consumption and the assessment of the nutritional value of the products used. The research results can be applied to further scientific developments in the direction of providing the market with various types of products.

Food consuming behavior is a concern for good physiological, physical, psychological, and social health. An unbalanced eating habit may be related to several factors. The objective of the study was to investigate how the use of digital devices influences graduate students’ eating behavior. A cross-sectional study was conducted among 320 Masters of Philosophy (MPhil) scholars of Nepal Open University through an online survey. A Chi-square test and a binary logistic regression model were fitted to find the effect of digital devices on food consumption. There was a significant association between the duration of using a mobile phone, computer, and TV with the quantity of food consumed, preferred time of using a laptop with the quantity of food consumed, and the sitting position during the use of digital devices with the quantity of food consumed. The logistic regression model showed that individual’s sitting positions while using digital devices were significant predictors of food consumption at a 95% confidence level.

Predators of herbivorous insects play important roles in tropical ecosystems as herbivory may affect structure and diversity of plant populations. Although insectivorous bats are particularly abundant and diverse in the tropics, their impact on herbivorous insects is little understood. To assess prey consumption, we observed the gleaning bat Micronycteris microtis (Phyllostomidae) continuously for 3 mo including 16 full nights at a nightly feeding roost on Barro Colorado Island in Panama using infrared videotaping combined with collection of prey remains. Individual bats consumed about 61–84% of their body mass in arthropods per night. Diet analysis revealed a high percentage of herbivorous insects, constituting more than half (51%) of all prey and over 70% of prey biomass. Dominant prey were caterpillars (33% of prey biomass), and other herbivores including crickets, katydids, scarab beetles and phasmids. Furthermore, a novel feeding behaviour was observed as M. microtis selectively discarded parts of intestines of phytophagous insects before consumption, probably to avoid intake of plant material either for ballast reduction and/or for protection from secondary plant compounds. Combined with estimated feeding rates of insects in sympatric bat species, our data suggest that gleaning bats are important predators of herbivorous insects and might be under-estimated reducers of herbivory in the tropics.
