Farmers must conform to Best Management Practices in fish production such as the development of non-antibiotic dietary supplements for growth and health management. We determined effects increasing levels mannan oligosaccharides on growth, immune system intestine integrity Nile tilapia. Fish (49.6 ± 10.8 g) were randomly distributed into 12 tanks (250 L; 20 per tank) fed during 60 days with a practical diet supplemented 0.0, 0.2, 0.4 0.6% (n = 3). not affected (P > 0.05) by treatments....
The aim of this study was to assess the effects three strains Bacillus thuringiensis (Bt) on longevity workers Africanized honey bee. Solutions at a concentration 3 × 108 spores.mL-1 (dosage) were prepared for each strain Bt (IPS 82, BR 81, and 147). Three bioassays performed as follows: spraying bees, contact with sprayed surface, candy paste incorporated Bt. bees bioassay submitted histological analysis mesenteron. assessed from one 120 hours using different ranges. It found that exposed...
ABSTRACT: The present study had the objective of evaluating longevity A. mellifera workers fed on a diet incorporating commercial entomopathogens, Beauveria bassiana, and Bacillus thuringiensis. It also aimed at verifying possible morphological alterations in midgut. To this purpose, entomopathogens used were B. bassiana (Product A) (5.0 × 1011 viable conidia.kg-1), thuringiensis B) (2.5 109 spores.g-1), C) (1.0 spores.g-1); two controls: T1: sterilized distilled water, T2: water + Tween 80®...
Brazil became the largest consumer of pesticides in world 2021. These products, although necessary, can cause significant damage to non-target organisms and agroecosystems. From this perspective, search for new, safer products gains prominence every year. It is essential understand how react contact with these novel verify their safety. Therefore, vertebrate models, such as embryo Gallus gallus domesticus L., 1758 (Galliformes: Phasianidae), an organism from which results be extrapolated...
Techniques for counting ovariole number in virgin and mated Apis mellifera L. queens have been described previous studies. Having a systematic fast way to collect this measurement can help accelerate bee breeding programs, because selection decisions be taken faster. The aim of work was develop an efficient histological method preserve ovaries that allows assessing the ovarioles newly emerged queens, also shorter time than methods already published. proposed resulted images suitable both...
This work aimed to evaluate the antimicrobial effect of Ganoderma lucidum mycelial growth filtrates (MGF) on phytopathogen Erysiphe diffusa and their potential effects embryonic development Gallus gallus. The activity was evaluated E. spores by microdilution broth method. To embryotoxic teratogenic effects, fertile eggs G. gallus received injections solutions containing through air chamber. After three days incubation, we opened egg viability, embryo survival, malformation occurrence, staging...
Honey bees are the main pollinators, but they in decline and synthetic phytosanitary products (SSPs) suspected to be related. Therefore, this study aimed evaluate effect of three commercial SPPs, used control stink bug soybean, formulated with Acetamiprid + Alpha-cypermethrin; Imidacloprid Beta-Cyfluthrin Fenitrothion Esfenvalerate, on adult worker Africanized Apis mellifera. For this, honey was exposed SPPs through bioassays: 1) sprayed bees, 2) Petri dishes which subsequently placed, 3)...
