Asclepias curassavica L. plant is toxic for vertebrates, and little is known about its effects on invertebrates, as well as whether its secondary metabolites have an influence on food preference and survival of insects. Thus, a study was conducted to verify the action of A. curassavica on Spodoptera frugiperda J.E.Smith. The plants were collected, dried and ground to compose a crude ethanolic extract. Food tests were carried out with and without opportunity of choice, using corn leaf discs immersed in the extract at concentrations of 1%, 2% and 4%, for assessment of food consumption (g) and preference index. Later, the extract was topically applied on second- and fifth-instar caterpillars, at concentrations of 1%, 2%, 4% and 6%, in order to observe its effect on survival. In parallel, analysis was conducted to verify the presence and measure the amount of total polyphenols and flavonoids in the extract. There was contact action between the extract and second-instar caterpillars at all concentrations, with treatment 6% causing 100% of mortality 72 hours after application. None of the treatments promoted contact action on fifth-instar caterpillars. In food tests with and without opportunity of choice, all treatments caused reductions in consumption, which classified all as phagodeterrent, with treatment 4% standing out as the least favorite. The presence of total polyphenols and flavonoids was found in the extract, presenting 58.75 ug/mL and 150.1 ug/mL, respectively. The A. curassavica extract proved promising in S. frugiperda control.

Lipid metabolism and dietary choices directly affect the outcome of overall weight management in both lean and non-lean individuals. However, the perception of consuming spicy foods has diverse meaning among people. To understand this, it is essential to have thorough knowledge on how food preference is tied to health outcomes. The aim of this study is to enhance the understanding of how food preference affects the health outcome and perception in lean and non-lean populations. A mixed methods study was conducted via analysis of consumers’ food choices and compared the data based on age, gender, and body weight. The participants in audio recorded interviews were comprised of residents from a single town in a rural state. The study shows that most participants were aware of the implications that food choices had on their health status and it emphasizes the importance of understanding the differences between consumption of spicy and non-spicy foods. Spicy food consumption was associated with decreased overall portion size as well as increased satisfaction following the meal. Environmental factors, such as the influence of family and friends, impacted spicy food consumption according to most participants. The outcome of the study provides a comprehensive understanding of food preferences from a relatively large exploratory study. The observations made here show rudimentary associations between physical attributes and levels of food consumption. Future studies could further identify how certain attributes relate to food choices and levels of spicy food consumption in greater detail.

The scarabaeid <em>Leucothyreus femoratus</em> (Burmeister) is described as causing damage to oil palm leaves, marking its first report as a pest in Colombia. The presence of this insect has necessitated determination of its life cycle, biometrics and food consumption as important aspects of its biology. Experiments were conducted under laboratory conditions in the municipality of San Vicente, Santander, Colombia. Mass rearing of <em>L. femoratus</em> was conducted, simulating field conditions and eating habits under laboratory conditions. Its life cycle and description of its developmental stages were determined, taking into account stage-specific survival. The duration of the life cycle of <em>L. femoratus</em> was determined to be 170.4&plusmn;6.53, with an overall survival rate of 96.7%. Biometrical measurements were taken of the insect&rsquo;s width, length and weight. Adults are black, and males and females are differentiated by size and by colour of their legs. The width, length and weight of the insect are proportional to the growth stage. Daily food consumption rate was evaluated in adult <em>L. femoratus</em>, and damage to leaves of <em>Elaeis guineensis</em> is described. Adult <em>L. femoratus</em> consumed 13 mm<sup>2</sup> of foliage per day, and injury to leaves of <em>E. guineensis</em> was square or rectangular in shape. This insect&rsquo;s life cycle duration and size are factors that could be considered in determining its feeding habits and pest status. Details of the life cycle, physical description and consumption rate of <em>L. femoratus</em> can help in the development of strategies to manage its populations in oil palm plantations.

Konsumsi makanan seseorang dipengaruhi oleh faktor ekonomi, faktor budaya, ketersediaan pangan, tingkat pendidikan, dan gaya hidup. Pengenalan berbagai jenis makanan tertentu sejak usia dini oleh keluarga mempengaruhi remaja dalam memilih makanan yang tergambar dari rasasuka atau tidak suka terhadap makanan secara kuat. Sekolah Menengah Atas (SMA) Adabiah merupakan salah satu sekolah swasta ternama yang ada di Kota Padang dan lokasi SMA tersebut cukup strategis berada di pusat Kota Padang. Berdasarkan hasil penelitian sebelumnya di SMA Adabiah tahun 2008 didapatkan sebesar 16% siswa mempunyai status gizilebih. Tujuan penelitian ini untuk mengetahui faktor-faktor yang berhubungan dengan pemilihan makanan pada siswa SMA Adabiah Padang. Desain penelitian ini adalah cross sectional dengan sampel siswa kelas 1 dan 2 yang berjumlah 111 orang. Hasil penelitian menunjukkan dari semua jenis makanan, responden paling menyukai buah-buahan (86,5%) dan paling tidak suka pada makanan sumber protein nabati (63,1%). Faktor-faktor yang berhubungan secara bermakna dengan pemilihan makanan adalah alergi terhadap pemilihan makanan sumber protein hewani, remaja pria terhadappemilihan buah-buahan, dan aroma makanan terhadap pemilihan makanan pokok. Oleh karena itu, perlu dilakukan pendidikan kesehatan kepada remaja mengenai konsumsi makanan yang bervariasi dan seimbang.Kata kunci: Konsumsi makanan, pemilihan makanan, remaja, status giziAbstractFood consumption was associated to economic, culture, education and life style. Introducing variety of food in early age influences teenager in choosing food. Food preferences was the degree of like or dislike for food. Adabiah Senior High School is one of famous schools in Padang, located in center of Padang town which is very strategic. In this school, last researchindicated that 16% students were overweight. The aim of this research is to know factors related with student food preferences at Adabiah school in Padang. A cross sectional study was conducted with 111 samples. The result showed that 86,5% of respondents like fruits very much, while 63,1%dislike non-animal protein Factors related with food preferences were allergy to animal protein, boys for preferences of fruits and food smell for preferences of main food. Our suggestion are health education to teenager about variation and balance of food consumption for their nutritional and health status.Key words: Food consumption, food preference, teenager, nutrition status
