Graphical AbstractAbstract.The increase in the volume of agroindustrial, agricultural and domestic solid wastes entails a series of implications related to health and environmental aspects. The objective of this research was to determine the chemical composition of agroindustrial residues of shelled peanuts, peanuts in shell, banana peels, cassava peels, shelled beans and beans peas for use in pig feeding. The contents of matter (DM), organic matter (OM), crude protein (PB), crude fiber (FB), ashes, ethereal extract (EE), nitrogen free extracts, ELN and gross energy EB, were determined in agroindustrial residues by the use of descriptive statistics, and mean and standard deviation were determined. Peanut and shelled peanut residues showed the highest content of MS (91. ). Shelled beans had an acceptable ELN content (62.66%). In relation to the FB, the bean peel had the highest content (49.03 %). The banana peel and cassava presented the highest ash content (8.82 and 8.49 %) respectively. The agroindustrial by-products of shelled peanuts, peanuts, banana peels, cassava peels, peas and shelled beans presented a significant content of MS, MO, PB, ELN, EE, Ashes and EB, all suitable for use in pig feeding.

Abstract:Many amazon producers used to apply various agrochemicals on crops of naranjilla (Solanum quitoense Lam.) with the objective of controlling different pests, and also increasing the size of the fruit. This kind of crop has a very high acceptance among the producers of Pastaza province. The low level of identification of Trips Palmi leads us to believe that the symptomatology and damages are associated with the phytotoxicity of the plant caused by the various pesticides, masking the high incidence of this pest and generating a decline in yields. This has an impact on economy of producers and for this reason, it was necessary to carry out this research in order to determine the impact of T. Palmi on crops of naranjilla. This experiment took place in two different productive farms located in the community of San Cristoball, canton of Santa Clara in Pastaza province. A sample of 35 plants was taken to identify the pest first. It was indispensable to know the specific location for which quantity and quality variables were proposed. It was demonstrated that, in the quantity variable (plant height), there were highly significant differences, in comparison with the average values between farms at all times (days: 1, 8, 16 and 24). It became apparent that there is a 100% impact of Thrips Palmi in both farms. This pest is located on the upper side of young leaves causing chlorotic and rosulate yellowing in upper, middle and lower leaves as well.

Graphical Abstract AbstractThe objective of this research was to accelerate the composting process of solid waste generated in the agroindustry of the Amazon by inoculating composting beds with a solution of isolated native microorganisms on the surface of the CIPCA forests. The microorganisms identified in this work were 2 fungi Aspergillus fumigatus, Penicillum sp. And the bacteria Bacillus subtillis and Pseudomos fluorences. A biomass of microorganisms with a concentration of 1 X 10 7 CFU*mL -1 per isolated microorganism was applied and sprayed 4 L*m -1 3 of substrate to compost. The following variables were evaluated: temperature, humidity, pH, C/N texture and physical structure, organic matter, electrical conductivity and cation exchange capacity. The results indicated that the beds inoculated with the microbial solution reached the physical, chemical and biological characteristics of a mature compost with the difference of five weeks before the control bed. The response in these characteristics indicated that the inoculum solution significantly accelerates the composting process.

Several pulmonary snails search for and / or follow trails left by their species for purposes such as feeding, aggregation and reproduction. In the project characterization of the ecological behavior under controlled conditions among the individuals of the species Lissachatina fulica to know the frequency with which they follow the trail and directions made by their congeners, and with that to plan a later control of this pest, for these Variables such as the age, size and condition of the snail and the receiving snail were proposed. Nine treatments were performed during the day and at night. The directions chosen by the recipient snails were observed during the experiments, followed by statistical analysis of the data using the chi-square test, obtaining results in relation to the treated individuals versus the total of the repetitions of the treatments and the control. From the statistical processing, the three more significant treatments(C, D, H) were selected, which were repeated at night. The results show that the treatment C is significant and its ecological behavior indicates that a number of snails follow the trail, concluding that there is a chemical communication between juvenile snails, being designated as the best treatment, nevertheless treatment H was also statistically significant. However it was defined as the worst treatment, since its ecological behavior is similar during day and night, the individuals don't follow the trace demonstrating that there is no chemical communication between adult and juvenile snails. Between adult and juvenile snails.
