The COVID-19 pandemic poses a threat to global food security, and it changes consumers’ food buying and consumption behavior. This research not only investigates trends in Spanish consumers’ general food shopping and consumption habits during the lockdown, but also investigates these trends from the perspective of sustainable purchasing. Specifically, total food consumption (C), food expenditure (E), and purchase of food with sustainable attributes (S) were measured. Data were collected from a semi-structured questionnaire which was distributed online among 1203 participants. The logit models showed that gender, age, employment status, and consumers’ experiences were associated with total food consumption and expenditure during the lockdown. In addition, consumers’ risk perceptions, shopping places, trust level in information sources, and risk preference were highly essential factors influencing consumers’ preferences and sustainable behavior. Consumers’ objective knowledge regarding COVID-19 was related to expenditure. Furthermore, family structure only affected expenditure, while income and place of residence influenced food consumption. Mood was associated with expenditure and the purchase of sustainable food. Household size affected purchasing behavior towards food with sustainable attributes. This research provides references for stakeholders that help them to adapt to the new COVID-19 situation.

Total Food Consumption

Abstract The response of German cockroaches to MaxForce, a 0.05% hydramethylnon bait (Clorox Co.), in the presence of an alternate food source, was evaluated. Also, survivors were saved, mated, and progeny tested to investigate the possible development of either physiological or behavioral resistance. Cockroaches were from 5 field-collected strains from different geographic localities. Ten male and 10 female 6th instars were starved overnight, placed in 5 gal aquaria, and given a choice of dog chow or bait. Tests were run for 48 h. Mortality was recorded during and after the test until 2 d passed with no further death. Bait and dog chow consumption was determined (mg). Bait preference/avoidance was evaluated by dividing bait consumption by total food consumption (bait + dog chow). Six to 8 replicates were done on each strain in each generation.

The paper aims to analyse the contemporary situation on markets with selected organic products in the Czech Republic as well as in selected European countries. The attention is paid especially to the share of organic products´ consumption (cereals, potatoes, fruits, vegetables, milk, pork, poultry and eggs) in the total food consumption in the Czech Republic, in Spain, in Sweden, in the Netherlands and in Great Britain.

Total Food Consumption

Atlantic salmon (Salmo salar) alevins presented with lake zooplankton in still water readily consumed prey items, but only if the prey were nearby and moving. Feeding was initiated from the bottom or from midwater, but no search or pursuit behavior was noted. Stomach analyses of alevins exposed to lake zooplankton assemblages for 3 h in still and flowing (7.2 cm∙s−1) water revealed that the two groups consumed similar diets, but that the still-water group had a greater total food consumption. We conclude that for alevins to feed successfully, food need not be carried in a water current, but that motion of the prey is necessary. This motion can be provided by water current or by the prey. The role of prey motility in the feeding of young salmonids is briefly discussed. Key words: Atlantic salmon, alevins, feeding, water current

Total Food Consumption

In Vietnam, agricultural practices such as fertilizer and pesticide use affect the landscape as well as the availability and safety of food. For instance, pesticides and fertilizer end up in surface water used for drinking water, crop irrigation, and in fish tanks. However, the link to actual food consumption and health is complex and information is lacking. This study considers potential water-related exposure to toxic hazards in northern Vietnam food systems, through the consumption of food commodities and of water. Water pollution is operationalized by considering the following two channels: (i) pesticide and nutrient leaching to surface water (share of surface water) and (ii) industrial runoff from facilities located in urban areas (share of urban areas). We explore how potential exposure to toxic hazard is related to food consumption choices. Using a sample of the Vietnam Household Living Standard Survey (VHLSS) for 2014, we estimate how shares of food consumption categories in total food consumption are affected by household and landscape characteristics, the latter also reflecting potential environmental pressures. In districts with higher shares of surface water, the share of fish consumption is higher and the share of meat consumption is lower. From an environmental and health perspective, households in water-rich areas thus may have a higher probability of being exposed to toxic chemicals due to higher fish consumption. In districts with higher shares of urban areas, the shares of meat and cereals in total food consumption value were lower, and the shares of fish and fruit and vegetables were higher. The results indicate that food consumption is affected by landscape characteristics that may also influence the level of exposure to water-related environmental pressures, and that this combined effect may potentially exacerbate food safety and health risks. The actual impact is more complex and should be analyzed with more sophisticated data and methods.

AbstractAn adult of either Coleomegilla maculata lengi or C. m. medialis ate about 280 mg dry Acyrthosiphon pisum in its lifetime at various constant temperatures. Total food consumption and rate of intake increased with temperature and rate did not vary with age. The average ages attained by field-collected and laboratory-reared adults were greatest at temperatures of 17° and 23 °C, respectively, for C. m. lengi and at 23 °C for C. m. medialis. Neither subspecies laid any eggs at 17 °C, C. m. lengi laid some eggs at 23 °C, and both subspecies laid the largest number of eggs at 25 °C. Fertility as percentage of eggs hatched was lower in both subspecies at 34 °C (30%) than at 23° and 25 °C (100%). Ethanol extracts of teak, cinnamon, clove, guaiacol, and resorcinol were the most effective ovipositional stimulants for C. m. lengi when formulated in water. Exposure to the ethanol extracts of different plants increased the incidence of oviposition by 19% and the number of eggs/♀/day by 36% in C. m. lengi.

ABSTRACTTwenty-one mature ewes of each of two breeds, the Scottish Black-face and the Welsh Mountain, were allocated in equal numbers to three diets based on a complete cobbed feed with a 0, 5 and 15% inclusion of dried seaweed meal (Ascophyllum nodosum). All diets were made up to a Cu content of approximately 30 mg/kg by adding CuSO4 to the mix. Sheep were housed and fed individually for 15 weeks.There was a significant breed difference in the Cu level of the liver dry matter; the Welsh increased by 316 mg/kg compared with 240 mg/kg in the Blackface and the amount of Cu accumulated in the liver per kg feed consumed was 0·66 mg in the Welsh and 0·46 in the Blackface. Diets also had a significant effect; the Cu levels in liver dry matter rose by 323, 293 and 220 mg/kg for the 0, 5 and 15% seaweed diets respectively and the Cu stored per kg feed consumed was 0·66, 0·61 and 0·41 mg respectively. There was no corresponding effect of diet on plasma Cu level, but there was a breed difference with Welsh higher than Blackface. Cu level in kidney dry matter showed a breed-by-diet interaction. Total food consumption did not differ among the treatments, and live-weight and carcass-weight data suggested no adverse effects from the inclusion of seaweed meal in the diet.
