Biological Control of Aphids

1999
Research into biological control of aphids continues. However, because of the high growth rates of aphid populations, it is unlikely that they can be fully controlled in all cases. Correct cultural practices (e.g. avoiding nitrogen overfertilization) may reduce the rate of increase of aphid populations and enhance the effectiveness of biological ...

Biological Control in the Phyllosphere

Annual Review of Phytopathology, 1992
This article considers biological control in the leaf-surface habitat within a broad ecological context, with emphasis on plant-microbe interactions. The form of biocontrol discussed is microbial antagonism by epiphytes or en­ dophytes. Thus, for the sake of some focus, I do not consider mechanisms such as induced resistance, cross protection, and ...

Biological control.

2019
Abstract Parthenium weed (Parthenium hysterophorus) is susceptible to herbivory, but there are no herbivores or pathogens in the introduced ranges that are known to exert any critical impact on parthenium weed. Classical biological control, using host-specific (highly selective) natural enemies introduced from the native range of the plant, to ...

Chitinases in biological control

1999
The public concern over the harmful effects of chemical pesticides on the environment and human health has enhanced the search for safer, environmentally friendly control alternatives. Control of plant pests by the application of biological agents holds great promise as an alternative to the use of chemicals.

Biological control in Jamaica.

2020
Abstract Jamaica has a rich history of successful biological control of more than 25 pests of economic and quarantine importance. Approximately 14 classical, 13 natural and six augmentative biocontrol programmes were recorded, as well as two fortuitous introductions.

VEGF in biological control

Journal of Cellular Biochemistry, 2007
AbstractVascular endothelial growth factor A (VEGF‐A) belongs to a family of heparin binding growth factors that include VEGF‐B, VEGF‐C, VEGF‐D, and placental‐like growth factor (PLGF). First discovered for its ability to regulate vascular endothelial cell permeability, VEGF is a well‐known angiogenic factor that is important for vascular development ...

Biological Control

2011
Ecological problems created by chemical insect control methods and their relevance to human health are receiving serious attention everywhere. There are two types of economic problems caused by insects. One concerns the loss of production that results from damage to crops and the effect on the health of human beings and also the health of domestic ...

Biological control of helminths

International Journal for Parasitology, 1999
As a potential component in future integrated parasite-control strategies, biological control by means of predacious fungi seems to be moving from a promising possibility toward becoming a reality, and the netforming nematode-destroying fungus Duddingtonia flagrans appears to be the candidate of choice.

Biological control in Belize.

2020
Abstract Parasitoids were first introduced into Belize in 1969 for control of Anastrepha spp. fruit flies, but although this and other classical biocontrol attempts sometimes resulted in establishment, control was insufficient. During the same period, natural control of the West Indian cane fly was documented.
