Abstract:

In the prevention of parasitic diseases, an important place is occupied by the search for new chemical preparations for disinvasion. The selection criterion is often the ovicidal efficacy of drugs against helminth eggs. The study of ovicidal efficacy is a rather laborious process that requires certain skills. In publications devoted to this topic, very little space is given to methodological issues. The traditional methods of testing and selection of drugs for disinfestation, proposed by the guidelines, have not changed much over the years. This article describes a new improved method for dete

Abstract:

Equine farming faces growing challenges with helminthoses, aggravated by the indiscriminate use of anthelmintics without technical criteria. This practice favors resistance to these drugs, generates residues in animal products, compromises food safety and human health, and, when excreted in large quantities, negatively impacts environmental health by affecting invertebrates and fecal microorganisms. This highlights the importance of the One Health approach. A promising alternative is biological control with nematophagous or helminthophagous fungi such as Duddingtonia flagrans, Pochonia chlamyd

Abstract:

ABSTRACT Incident Action Plans (IAPs) are one of the most effective ways for an Incident Commander (IC) or Unified Command (UC) to convey to the established response organization the goals and objectives that must be accomplished to mitigate an event. These plans come in many forms, from simple ones written on a blank sheet of paper to book size plans produced by a computer. Regardless of the form used, they must all successfully convey the IC's or UC's intentions, while being flexible enough to handle changes brought on by unseen events. If the plan is not “user-friendly,” then field personne

ABSTRACT: The red mite Oligonychus yothersi is one of the main pests of yerba mate in Brazil The damage this mite causes leads to leaf drop and decreased production. There are no registered acaricides for use in yerba mate; thus, laboratory and field experiments were performed to evaluate the effect of azadirachtin (Azamax(r), 250mL 100L-1) for the control of the red mite in yerba mate. In the laboratory, azadirachtin was applied to yerba mate leaf disks before (residual contact) and after (direct contact) infestation with 15 newly emerged red mite adult females.

Abstract:

Dysdercus peruvianus is a hemipteran insect known as arrebiatado or cotton stainer bug that, due to its habits and morphological characteristics, affects the quality of fiber in cotton crops, with synthetic pesticides being the first barrier to control. However, excessive use has adverse effects on health and the environment. Therefore, plant extracts represent a sustainable alternative for pest control. In this study, the in vitro ovicidal activity of “matico”, Piper tuberculatum, on D. peruvianus was evaluated, determining the ovicidal effectiveness, lethal concentration (LC50) and lethal ti

Based on the results obtained during the experiments, carried out under in vitro conditions it was found that 3.0% and 5.0% solutions of the deltatrine preparation destroy nematode eggs by 100%, and 3.0% and 5.0% solutions of the citrine preparation by 72.2-80.0%. In a concrete test object, with a 3-hour exposure, helminth eggs (1200 eggs) were destroyed by 100% from the impact of a 3.0% deltathrine preparation, by 63.6

The mosquito species Aedes aegypti is one of the main vectors of arboviruses, including dengue, Zika and chikungunya. Considering the deficiency or absence of vaccines to prevent these diseases, vector control remains an important strategy. The use of plant natural product-based insecticides constitutes an alternative to chemical insecticides as they are degraded more easily and are less harmful to the environment, not to mention their lower toxicity to non-target insects.

This suggests they have strong fumigant and ovicidal properties. While camphor oil @ 5 ml per Kg also showed some effectiveness, it has low potency compared to other treatments, resulting in only 75 per cent adult mortality and allowing some new ad

The widespread use of synthetic chemical pesticides beginning in the late 1930s has contributed to the development of insecticide resistance of many important species of pest insects and plants. Recent trends in pesticide development have emphasized the use of more environmentally benign control methods that take into consideration environmental, food safety, and human health. Biopesticides (e.g., naturally occurring pesticidal compounds) are alternative pest management tools that normally have no negative impact on human health or the environment.
