Abstract Native to the neotropics, the avocado seed moth Stenoma catenifer Walsingham (Lepidoptera: Elachistidae) is a specialist pest of the family Lauraceae and considered one of the most important pests of avocados worldwide. However, little is known regarding its spatial distribution within a single tree. Therefore, we designed a study to evaluate the effects of canopy height and aspect (i.e., side of the tree) on fruit infestation by S. catenifer larvae in avocados. The study was conducted in three commercial organic avocado orchards located in São Paulo, Brazil. At each orchard, 40 fruit from 30 random trees were sampled weekly from October 2017 through February 2018, evaluating the number of fruits infested by S. catenifer larvae at three tree heights (bottom, middle, and top). In addition, fruits on the ground were also sampled. We also evaluated the effect of the side of the tree where the fruits were collected, i.e., whether they were on the side facing the east (sunrise) or the west (sunset). Within the avocado canopy, the level of fruit infestation by S. catenifer larvae was significantly higher at the top of the trees than in the middle and bottom. Fruit on the ground had lower levels of infestation than those on the tree canopy. The level of fruit infestation was also higher on the side of avocado trees facing the east (sunrise). Understanding the within-tree distribution of S. catenifer will help to better target monitoring and control activities against this pest in avocados.

Fruit flies belong to the Tephritidae Family which is one of the largest within the Order Diptera. This family is among the pests with the greatest economic expression in the world's fruit industry, as they attack the reproductive organs of plants, fruits with pulp and flowers. These insects are an important group of pests in the fruit industry worldwide, as they have a life cycle in which their larval period develops especially inside the fruits, feeding, in general, on their pulp. The objective of this study is to report the Ecology and Biology of Tephitidae. The research was carried out in studies related to quantitative aspects of the Family, Subfamily and Species (taxonomic groups) and conceptual aspects such as: biology, geographical distribution, methodologies, and traps for collecting and their parasitoids and strategies for Drosophlidae with control, species, life cycle, damage, economic importance, medicinal importance, biological aspects, monitoring and control and reproduction. A literature search was carried out containing articles published from 1993 to 2021. The mini-review was prepared in Goiânia, Goiás, from September to October 2021, through the.

Bat (Chiroptera) are a type of mammal that has an important ecological role for the sustainability of the forest, including helping to spread seeds, flower pollination, and control insect population. Bats have adapted well to various habitats, including urban forests. The purpose of this research is to search bats diversity data in the area of Tanjungpura University, Pontianak. Method of this research using the capture and release by using a mist net, placed purposively, by looking at the bat path. The Mist net was installed around tree canopy layers at 3 research locations, new campuses, old campuses, and the Arboretum. Based on the location of the observation, the number of species and types found in three locations is the same. There are 2 species of the family Pteropodidae including the sub-order Megachiroptera, Cynopterus brachyotis and Cynopterus minutus. Data analysis results show that no type of bat dominates from three observation locations, the dominance index is < 1. Diversity of Bats from all three locations shows < 1 which includes low diversity index criteria. The evenness of bats from all three observation locations has a criteria value of > 0.5 meaning the community at all three observation locations is the lability community to the stable.

Hippoboscidae Samouelle, 1819 is a family of flies (Diptera) consisting of species that are obligatory parasites of several species of mammals and birds. The family includes winged species, with good or reasonable flight capacity, and species with vestigial or even absent wings, incapable of flight and with strong apomorphy. The objective of this collection consists of bibliographical research on the Muscoid dipterans of the Hippoboscidae Family. The research was carried out in studies related to quantitative aspects of the Family, Subfamily and Species (taxonomic groups) and conceptual aspects such as: biology, geographical distribution, methodologies, species, life cycle, damage, economic importance, medicinal importance, biological aspects, monitoring and control and reproduction. A literature search was carried out containing articles published from 1940 to 2021. The mini-review was prepared in Goiânia, Goiás, from September to October 2021, through the.

Oestridae is a family of flies, which includes species whose larvae are internal parasites of several species of mammals. Some species settle in the host's flesh, while others occur in the viscera. This study objective to report the characteristics of the Family Oestridae. The research was carried out in studies related to quantitative aspects of the Family, Subfamily and Species (taxonomic groups) and conceptual aspects such as: biology, geographical distribution, species, life cycle, damage, laboratory creation, economic importance, medicinal importance, biological aspects, monitoring and control and reproduction. A literature search was carried out containing articles published from 1950 to 2021. The mini-review was prepared in Goiânia, Goiás, from September to October 2021, through the Online Scientific Library (Scielo), internet, ResearchGate, Academia.edu, Frontiers, Publons, Qeios, Portal of Scientific Journals in Health Sciences, Pubmed, Online Scientific Library (Scielo), internet, ResearchGate, Academia.edu, Frontiers, Biological Abstract, Publons, Qeios, Portal of Scientific Journals in Health Sciences, and Pubmed, Dialnet, World, Wide Science, Springer, RefSeek, Microsoft Academic, Science, ERIC, Science Research.com, SEEK education, Periódicos CAPES, Google Academic, Bioline International and VADLO.

Personal computers (PCs) are a powerful resource in the EM Laboratory, both as a means of automating the monitoring and control of microscopes, and as a tool for quantifying the interpretation of data. Not only is a PC more versatile than a piece of dedicated data logging equipment, but it is also substantially cheaper. In this tutorial the practical principles of using a PC for these types of activities will be discussed.The PC can form the basis of a system to measure, display, record and store the many parameters which characterize the operational conditions of the EM. In this mode it is operating as a data logger. The necessary first step is to find a suitable source from which to measure each of the items of interest. It is usually possible to do this without having to make permanent corrections or modifications to the EM.

A modern dairy farm is a complex biotechnical “man-machine-animal” system, where purposeful human activity concentrates mainly on the control of the “machine” and “animal” subsystems, thus making the whole system ergatic. Increasing the interaction effi ciency of machine subsystems with biological objects (animals) requires an in-depth study of the properties and characteristics of the latter, their behavior, adaptive and refl ex mechanisms that ensure the mutual adaptation of machine and biological subsystems. The paper considers general functionality of the “animal” subsystem, which includes lists of monitored parameters (functions) in pre-weaning, pre-lactation and lactation periods. In a similar way, functionals of the subsystems of the general musculoskeletal development of the animal’s body, respiratory and digestive organs, comfort of the habitat, development and control of the reproductive organs of lactating cows were obtained accompanied with a list of controlled functions and parameters. To carry out a set of research activities in this fi eld, FSAC VIM is planning to carry out a complex project that will increase the levels of automation, digitalization and intellectualization of animal husbandry, provide for comfortable environment, optimal rediced-impact service modes for animals and their extended productive longevity, increased quality of milk and autonomous functioning of individual local biotechnical subsystems.
