“…[4][5][6] Alternative measures include biological control methods such as pasture spelling 7 and artificial selection for tick-resistant cattle. 8,9 Such steps can reduce tick burdens, but enhancement of host resistance through immunization would constitute a major advance in control. [10][11][12][13] Several approaches have been used to actively immunize cattle against ticks, [14][15][16][17][18][19][20][21][22] and it has been reported that protective host immune responses can damage female ticks, reducing tick populations on immunized cattle by up to 70%.…”

“…27 Crossbred Holstein-Friesian dairy cows are abundant in Thailand, which is a concern owing to the high vulnerability of these breeds to ticks and tick-borne diseases compared to the native breed. 9 There are substantial losses in milk production associated with tick infestation of dairy cows in Thailand. For example, it has been estimated that each engorging adult female tick is responsible for the loss of 8.9 mL of milk and 1 g of live weight gain.…”

Boophilus microplus has a major impact on cattle production, and an antitick vaccine would be a valuable tool for control of this important ectoparasite in Thailand. Previous work has shown that immunization of hosts with different tick tissues has different implications regarding tick feeding and fecundity under experimental conditions. The purpose of this study was to assess the effects of immunization of dairy cattle with B. microplus salivary gland or midgut extracts on natural infestations by this tick species. The different antigen extracts (1 mg total protein) or equivalent amounts of adjuvant alone were injected intradermally every two weeks for a total of three times before allowing cattle to graze in a tick-contaminated pasture. Animals were checked daily, and engorged female ticks collected, counted, weighed, and maintained in tick incubators to observe tick performance parameters, including engorged weight, egg mass weight, nonviable eggs, mortality, oviposition period, egg incubation period, and F1 larval weight. After six months, each group was reimmunized with the same antigen and/or adjuvant, and ticks were again collected and evaluated. Immunization of cattle with salivary gland preparations resulted in reductions in mean tick counts and in engorged female weights. Immunization with midgut antigens reduced tick oviposition and reduced egg mass weights. In addition, more ticks recovered from midgut-immunized cows produce nonviable eggs. This investigation indicates that a vaccine based on these antigen preparations could induce a lasting, protective immune response against B. microplus that would be expected to provide a safe nontoxic means of tick control.

“…For example, when control of Rhipicephalus appendiculatus, the vector of East Coast fever failed because of acaricide resistance, severe outbreaks of screw-worm occurred (Wharton and Norris, 1980). In some areas there is added complication because tick-bite lesions are highly attractive to screw-worm flies.…”

This paper examines social and economic aspects of integrated vector management in relation to the control of various vector-borne human diseases. The role of the human environment and activities in transmitting and in controlling human diseases is described. Common vectorborne human and domestic animal diseases in the tropics are listed and described in relation to their carriers (vectors), geographical regions of prevalence, approximate numbers of humans affected and likely remedial strategies. The benefits of integrated vector control as opposed to chemical control are discussed and supported with examples from various parts of the world. The paper ends by listing World Health Organisation recommendations on how to control human vector-borne diseases. ' ; Resume-Cet article examine les aspects sociaux et economiques de la lutte antivectorielle dirigee concernant la lutte contre de nombreuses maladies humaines transmises par des vecteurs. Le role de I'ehvironnement et des activity humaines dans la transmission et la lutte contre les maladies humaines y est decrit. Les maladies vectorielles communes a l'homme et aux animaux domestiques sous les tropiques sont 6numerees et decrites en relation avec leurs porteurs (vecteurs), les regions de prevalence, le nombre approximatif d'humains affectes et des strategies de prevention. Les benefices a tirer de la lutte antivectorielle integree, par opposition a la lutte chimique, sont disrates et soutenus par des exemples tires de plusieurs regions du monde. L'article se termine par Penumeration des recommandations de l'Organisation Mondiale de la Sante sur les modalites de lutte contre les maladies humaines transmises par des vecteurs.Mots Cl4s: vecteurs de maladie, maladies humaines transmises par des vecteurs, lutte antivectorielle integree, transmission de maladie, lutte biologique

“…Essas alterações ambientais podem interferir nas relações parasita-hospedeiro, principalmente dos ectoparasitas, por estes passarem mais de 90% de suas vidas no ambiente, fora do corpo do hospedeiro (LABRUNA et al, 2005). Isso afeta a vulnerabilidade dos vertebrados a esses parasitas e seus agentes patológicos, prejudicando tanto a saúde das espécies silvestres como a saúde humana e a de suas criações domésticas (WHARTON, 1976;BELTRAN, 1977;WHARTON;NORRIS, 1980;FURLONG, 1993;LYLES;DOBSON, 1993;GONZALES, 1995;OSTFELD et al;CORDOVES, 1997;PATZ et al, 2000;LABRUNA et al, 2005;ALMEIDA et al, 2006;. Desta forma, o estudo das relações dos parasitas com seus hospedeiros é de extrema relevância, principalmente em uma paisagem de constantes mudanças de uso do solo, na qual há contato da fauna silvestre com humanos e animais domésticos.…”
