background: essential oils, as secondary plant compounds, present a safer alternative to conventional insecticides in insect control programs. so five essential oils including eucalyptus, mint, yarrow, oregano and rosemary oils were evaluated against the brown-banded cockroach supella longipalpa . methods : evaluation was done against the 3 rd and 4 th instar nymphs using three bioassay methods...

ecology of anopheles dthali was studied in bandar abbas county, where there is indigenous malaria. anopheles dthali plays as a secondary malaria vector in the region. it is active throughout the year in mountainous area with two peaks of activity, whereas in coastal area it has one peak. there is no report of hibernation or aestivation for this species in the re gion. precipitin tests on specim...

zoonotic cutaneous leishmaniasis (zcl) is an increasing and important public health problem in iran. the use of repellents is recommended as one of the important means of personal protection against vectors of zcl. this paper reports the repellency effect of the plant myrtle, myrtus communis (myrtaceae), essential oil for protection against 3-7-day-old unfed females of the sandfly, phlebotomus ...

in this paper, the concept of {sl local base with  stratifiedstructure} in $i$-topological vector spaces is introduced. weprove that every $i$-topological vector space has a balanced localbase with stratified structure. furthermore, a newcharacterization of $i$-topological vector spaces by means of thelocal base with stratified structure is given.

this paper aims to assess the application of support vector machine (svm) regression in order to analysis flexible pavements. to this end, 10000 four-layer flexible pavement sections consisted of asphalt concrete layer, granular base layer, granular subbase layer, and subgrade soil were analyzed under the effect of standard axle loading using multi-layered elastic theory and pavement critical r...

identification of host blood meal in haematophagous arthropods is an important element in their rule in transmission of vector borne diseases. the effects of post ingestion and physical conditions that killed mosquitoes are stored on the success of detecting blood meal dna of anopheles stephensi and culex quinquefasiatus was investigated by polymerase chain reaction (pcr) amplification at the h...

background : ticks are important vectors and reservoirs of crimean congo hemorrhagic fever (cchf) virus. human beings may be infected whenever the normal life cycle of the infected ticks on non- human vertebrate hosts is interrupted by the undesirable presence of humans in the cycle. a total of 26 species of argasid and ixodid ticks have been recorded in iran; including nine hyalomma, two rhipi...

ba ckground: mosquitoes are well known as vectors of several disease causing pathogens. the extensive use of synthetic insecticides in the mosquito control strategies resulted to the development of pesticide resistance and fos- tered environmental deterioration. hence in recent years plants become alternative source of mosquito control agents. the present study assessed the larvicidal and ovipo...
