Environmental Health Perspectives, 1994 On page 390 of the October issue of EHP (volume 101, number 5), there is a graph that purports to show the intake of pesticides by children in milligrams per kilogram per day. I think you owe a prominent correction/explanation to your readers. The original figure in the National Academy of Sciences report (figure 5-1, p.

On the paradox of pesticides [PDF]
arXiv, 2013 The paradox of pesticides was observed experimentally, which says that pesticides may dramatically increase the population of a pest when the pest has a natural predator. Here we use a mathematical model to study the paradox. We find that the timing for the application of pesticides is crucial for the resurgence or non-resurgence of the pests.

Modelling the inhibiting effect on a microbial pesticide model [PDF]
arXiv, 2022 Microbial pesticides can avoid many of negative effects of traditional chemical pesticides. To modelling the inhibiting effect, in this paper we propose a model of entomopathogenic nematodes killing the target insects, and inhibiting the birth rate of the target insects simultaneously.

A smartphone application to measure the quality of pest control spraying machines via image analysis [PDF]
, 2017 The need for higher agricultural productivity has demanded the intensive use of pesticides. However, their correct use depends on assessment methods that can accurately predict how well the pesticides' spraying covered the intended crop region. Some methods have been proposed in the literature, but their high cost and low portability harm their ...

Öffentliche Daten auf die nächste Stufe heben -- Vom RESTful Webservice für Pflanzenschutzmittelregistrierungsdaten zur anwendungsunabhängigen Ontologie (erweiterte Version) [PDF]
arXiv, 2023 During the application of chemical pesticides, distance requirements have to be considered. However, these have to be determined and considered by the farmer manually. To support the farmer the Pesticide Application Manager (PAM)-Projects were conducted and a decision support system was developed.

Binding proteins of destruxin A from Metarhizium against insect cell
BMC Microbiology, 2023 Destruxin A (DA) is a cyclo-hexadepsipeptidic insecticidal mycotoxin isolated from the entomopathogenic fungi, Metarhizium spp. However, its mode of action is unknown. In this study, we isolated 149 candidate DA-binding proteins by drug affinity response

Mediation Analysis using Semi-parametric Shape-Restricted Regression with Applications [PDF]
arXiv, 2023 Often linear regression is used to perform mediation analysis. However, in many instances, the underlying relationships may not be linear, as in the case of placental-fetal hormones and fetal development. Although, the exact functional form of the relationship may be unknown, one may hypothesize the general shape of the relationship. For these reasons,

Acta Neuropathologica, 2019 Pesticides are unique environmental contaminants that are specifically introduced into the environment to control pests, often by killing them. Although pesticide application serves many important purposes, including protection against crop loss and against vector-borne diseases, there are significant concerns over the potential toxic effects of ...
