<p class="Judul1"><span lang="EN-US">Pediculosis is a disease caused by infestation of head lice (<em>Pediculus humanus capitis</em>) which is a blood-sucking obligate ectoparasite. The essential oil of durian fruit peel has active compounds that have the potential as vegetable pediculosides that can kill head lice. This study aimed to find the best concentration <span>of </span>essential oil from durian fruit peels that can kill head lice. The research design used with an essential oil concentration of 100%, 75%, 50%, 25%, distilled water as negative control and permethrin 1% as positive control, three repetitions and each concentration consisting of 10 flea tails. The parameters observed were the condition of lice morphologically based on the activity of limb movement, antenna movement and digestion, then the calculation of mortality was observed based on the time of the test. The results showed that the concentration of durian peel essential oil as an antipediculosis had a significant effect on the time of death of head lice, limb movement and digestion. The test result showed that the concentration is 100%, has a death time of 12 minutes <span>32 </span>seconds, 75% concentration was 16 minutes 28 seconds, 50% concentration was 21 minutes 11 seconds, 25% concentration was 32 minutes 23 seconds, negative control was 61 minutes 15 seconds. The fastest time of death in positive control for chemical pediculosides was 10 minutes 15 seconds. The conclusion in this study was that essential oils the dominan one is 1,5-naphthyridin-2-amine were proven to kill head lice and the best concentration was close to positive control, namely at a concentration of 100%.</span></p>

Amplicon Size

In this study, only (122) out of (915) primary school students were shown to be infected with head lice Pediculus. humanus capitis. The number and percentage of infected males were 46 (11.3%), while the number and percentage of infected females were 76 (14.9%). The results in our study also showed that the number and percentage of goats infected with goat sucking lice, Linognathus stenopsis was 70 (21.7%) of the total 322 animals, with the highest number and percentage among female goats 44 (62.9%) compared to the male goats 26 (37.1%). The study demonstrated that the rate of genetic difference between the studied samples was 89% and the similarity rate was 11%. Detection of OP-K01 gene pieces by PCR products showed that the amplicon size was 520 bp for P. humanus capitis isolated from humans, while the detection of OP-E20 and OP-M05 gene pieces with PCR product showed the lowest amplicon size 230 bp for Linognathus stenosis isolated from goats.

Mechanical Methods

Chemical, physical, and mechanical methods are used to control human lice. Attempts have been made to eradicate head lice Pediculus humanus capitis by hot air, soaking in various fluids or asphyxiation using occlusive treatments. In this study, we assessed the maximum time that head lice can survive anoxia (oxygen deprivation) and their ability to survive prolonged water immersion. We also observed the ingress of fluids across louse tracheae and spiracle characteristics contrasting with those described in the literature. We showed that 100% of lice can withstand 8 h of anoxia and 12.2% survived 14 h of anoxia; survival was 48.9% in the untreated control group at 14 h. However, all lice had died following 16 h of anoxia. In contrast, the survival rate of water-immersed lice was significantly higher when compared with non-immersed lice after 6 h (100% vs. 76.6%, p = 0.0037), and 24 h (50.9% vs. 15.9%, p = 0.0003). Although water-immersed lice did not close their spiracles, water did not penetrate into the respiratory system. In contrast, immersion in colored dimeticone/cyclomethicone or colored ethanol resulted in penetration through the spiracles and spreading to the entire respiratory system within 30 min, leading to death in 100% of the lice.

Head Lice Infestation

The prevalence of head lice (Pediculus humanus capitis) infestation was studied among the children (1 to 7 years) in the area of Mirpur Bihari Camp, Mirpur-11, Dhaka. A total of 300 children was examined from February 2011 to January 2012 and 59.67% prevalence of head lice infestation was observed. The prevalence of pediculosis was significantly higher (p<0.05) in seven years aged children and the prevalence was significantly (p<0.05) higher in girls (72.62%) than boys (43.18%). School going children had higher (p<0.05) prevalence compared to preschool group. According to socioeconomic status, head lice infestation occurred almost equally in all social classes.
