Diamondback moth (DBM), Plutella xylostella L., is a devastating pest of cabbage worldwide whose feeding attributes are influenced by glucosinolate profiles of the plant. Identifying the specific glucosinolates associated with plants' resistance mechanism can provide cues to novel points of intervention in developing resistant cultivars. We studied the DBM larval feeding preference and extent o...

A study on symptoms of damage and ovipositional preference tea mosquito bug (TMB), Helopeltis antonii Signoret was done guava, moringa neem. survey conducted in villages Dindigul Theni districts Tamil Nadu, India for observing damage. In the feeds both new flush fruits, causing irregular necrotic spots young leaves corcky out growths fruits. moringa, flowers dry-up give wilted appearance. neem,...

Host plant water status is thought to influence dispersal of the xylophagous leafhopper Homalodisca vitripennis Germar, especially where plants are grown under high evaporative demand. Preference by adult H. vitripennis for plants grown under different water deficit and nitrogen form fertilization regimens was studied under laboratory conditions. Leafhopper abundance and ovipositional preferenc...

One of the most troubling aspects of ecosystem models is the use of rather arbitrary feeding and preference functions. The predictions of plankton functional type models have been shown to be highly sensitive to the choice of foraging model, particularly in multiple prey situations. Here we propose ecological mechanics and evolutionary logic as a solution to diet selection in ecosystem models. ...

To study the neuroendocrine mechanism of sugar preference, we investigated the role of glucose feeding in the regulation of expression levels of neuropeptides derived from proopiomelanocortin (POMC) in the lateral hypothalamus (LH) and nucleus accumbens (NAc) in fructose preference rats. Fructose preference rats were induced by using the lithium chloride backward conditioning procedure. The fru...

Optimal feeding is often constrained by predation avoidance, which may direct feeding to take place on more sheltered, but less profitable, parts of the habitat. Though constrained, feeding preferences and/or digestive capabilities should coevolve with the energetic and nutritional needs of the animal. These needs, as well as risk taking for these goals, may differ between the sexes. We studied...

Objective: The impact of different weaning methods on food preferences and body mass index (BMI) in early childhood is not known. Here, we examine if weaning methoddbaby-led weaning versus traditional spoon feedingdinfluences food preferences and health-related outcomes. Design, setting and participants: Parents (n1⁄4155) recruited through the Nottingham Toddler laboratory and relevant internet...

Abstract Date Presented 04/02/2022 The Child Assessment of Function Eating (CAFE) was designed to provide a comprehensive feeding assessment, with all major components (self-feeding, self-drinking, mealtime behavior, oral-motor skills, sensory food preferences, nutritional intake) in one assessment. This poster will present the normative data obtained from 63 children ages 3-7 years who were ev...

We have previously identified Usp46, which encodes for ubiquitin-specific peptidase 46, as a quantitative trait gene affecting the immobility time of mice in the tail suspension test (TST) and forced swimming test. The mutation that we identified was a 3-bp deletion coding for lysine (Lys 92), and mice with this mutation (MT mice), as well as Usp46 KO mice exhibited shorter TST immobility times...

Recent studies provide evidence that high-fat diets (HF) trigger both i) a deficit of reward responses linked to a decrease of mesolimbic dopaminergic activity, and ii) a disorganization of circadian feeding behavior that switch from a structured meal-based schedule to a continuous snacking, even during periods normally devoted to rest. This feeding pattern has been shown to be a cause of HF-in...
