"The aim of the present work is to determine harmful and beneficial insects associated with tomato greenhouse cultivation in arid region El-Outaya (Biskra, Algeria). Insect trapping was conducted using yellow water plates glue traps. Faunistic data have revealed presence 2754 individuals distributed on seven orders, 33 families 38 species insects. From specific point view, majority these were r...

Because of the well established predictive association between plasma cholesterol concentration and ischaemic heart disease, we are apt to think of cholesterol as a harmful substance that we might be better without. It must be remembered, however, that cholesterol is essential for the normal functioning of the animal body. Herbivorous animals must satisfy all their requirements for cholesterol ...

The experiment was carried out in the conventional and organic experimental fields of Institute Agriculture - Karnobat, period 2019 2022. aim to study influence weed infestation cropping system pea (Pisum sativum (Linn.)) on beneficial harmful entomofauna. Six seven species insects from families three orders were found damage farming, respectively. Their density higher farming. most economicall...

The paper presents research related to the harmful effects of snowfall in Austrian pine and Scots plantations western part Republic Srpska. most common types tree damage are snow break snowfall. effect is more present at lower altitudes. Also, reflected reduction vitality damaged trees, which become suitable for attack other biotic factors, primarily insects fungi.

Pollination is the mechanical transfer of male pollen of a flower on the female stigma.This process has a fundamental role to survive the plants species.Since this process is invisible ,its importance has been ignored.Insufficient pollination can be harmful for the farmer instead of being useful.Pollination can be done via some ways.The most important ways are done by insects and wind.Pistachio...

Few investigations have been made of the species description trend of scale insects. The present study reports the discovery pattern and taxonomic efforts for this group based on global species and a literature dataset. In addition, three asymptotic models (Logistic, Gompertz, and Extreme Value) based on a discovery curve were used to predict the species number of scale insects. Our results sho...

In this study, we provide a discretized system of continuous dynamical model for enhancing crop production in the presence insecticides and insects. Crops are assumed to grow logistically but limited by an insect population that entirely depends on agriculture. To protect crops from insects, farmers use insecticides, their overmuch is harmful human health. We external efforts proportional gap b...
