Vector Control by Removal Trapping

The American Journal of Tropical Medicine and Hygiene, 1994
The classic approach to vector control where large tracts of land are treated with an insecticide has many shortcomings. These include high cost, chemical resistance of target species to many of the widely used insecticides, a lack of public acceptance, and the detrimental effect of sprays on nontarget species.

The biological control of disease vectors

Journal of Theoretical Biology, 2012
Vector-borne diseases are common in nature and can have a large impact on humans, livestock and crops. Biological control of vectors using natural enemies or competitors can reduce vector density and hence disease transmission. However, the indirect interactions inherent in host-vector disease systems make it difficult to use traditional pest control ...

Vector control

1998
Abstract The origin of vector control dates from the 1970s with the work of Professor Leonhard [1] and his student Blaschke [2]. An earlier dissertation described work of a similar nature by Hasse [3] who was a student of Professor Joetten at TH Darmstadt. Originally the approach was referred to as ‘field oriented control’.

Vector Control in Transportation Osteogenesis

Journal of Oral and Maxillofacial Surgery, 2005
To evaluate the ability to control vectors in the technique of transportation osteogenesis using 4 principles.Sixteen defects measuring approximately 30-180 mm were retrospectively evaluated. Vector control was attempted using a single or combination of the following principles: multiple linear vectors, exaggerated linear distraction ("sausage effect"),

Key processing with control vectors

Journal of Cryptology, 1991
A method is presented for controlling cryptographic key usage based on control vectors. Each cryptographic key has an associated control vector that defines the permitted uses of the key within the cryptographic system. At key generation, the control vector is cryptographically coupled to the key by way of a special encryption process.

Malaria vector analysis and control

Parasitology Today, 1992
Antivector measures in malaria control should aim for a cost-effective reduction of the transmission potential ideally to below the critical level for sustained transmission. The available measures include those that decrease vector abundance, vector-human contact and vector survival rate or that increase the length of the sporogonic cycle.

A method is presented for controlling cryptographic key usage based on control vectors. Each cryptographic key has an associated control vector that defines the permitted uses of the key within the cryptographic system. At key generation, the control vector is cryptographically coupled to the key via a special encryption process. Each encrypted key and

[Vector control and malaria control].

Medecine tropicale : revue du Corps de sante colonial, 1991
Vector control is an integral part of malaria control. Limiting parasite transmission vector control must be considered as one of the main preventive measure. Indeed it prevents transmission of Plasmodium from man to vector and from vector to man. But vector control must be adapted to local situation to be efficient and feasible.

Vector Control

2018
Abstract The chapter begins with a description of the scalar control of PMS motors. The fundamentals of PMS motor vector control (VC) are then presented with an eye on the analogy with DC motor operating principles. The VC of surface-mounted permanent magnet pole motors and interior permanent magnet (IPM) motors are presented in various ...

The Role of Sampling in Vector Control

The American Journal of Tropical Medicine and Hygiene, 1994
In most disease vector control programs of the world, little attention is given to sampling methodology for surveillance against importation of vectors, determination of vector distribution, vector incrimination, monitoring of entomologic risk factors, and evaluation of control.
