Traumatic myiasis agents in Iran with introducing of new dominant species, Wohlfahrtia magnifica (Diptera：Sarcophagidae)

Objective: To study agents of animal wound myiasis in various geographical districts of Fars province.Methods:of 10358 domestic animals have been visited from April 2011 to March 2012. The infected wounds in any parts of animal body were sampled by means of forceps.Results:This study has been done in Fars province, located in the southern part of Iran. Sums The most wound myiasis cases due to this species occurred in central part of Fars province. There wasn’t any significant difference between sheep and goat in infestation with myiasis (P>0.05). The infestation rate of myiasis in cattle community was 0.86%. About 61% of all animal wound myiasis were caused by larvae of Wohlfahrtia magnifica. Conclusions: The infestation rate of livestock was lower than other works in Iran and some other countries like Saudi Arabia. Chrysomya bezziana has been mentioned as main myiasis agent in Iran. But in this study it cleared that similarly to some European countries, the common animal myiasis agent in Iran is Wohlfahrtia magnifica. Introducing new species as principal agent for myiasis can help public health and animal husbandry policy makers to prepare sufficient and effective control and/or preventive measures for this disease.

First survey of hard ticks (Acari:Ixodidae) on cattle, sheep and goats in Boeen Zahra and Takistan counties, Iran

Objective: To carry out the distribution survey of hard ticks of livestock in Boeen Zahra and Takistan counties of Qazvin province from April 2010 to September 2010. Methods:Nearly about 2 638 sheep, 461 goats and 318 cattle of 38 herds in different geographical areas were searched for tick infestation. Results:The species compositions collected from the livestock of Boeen Zahra and Takistan were Haemaphysalis concinna (0.63%), Haemaphysalis sulcata (12.66%), Hyalomma anatolicum (3.80%), Hyalomma asiaticum (3.16%), Hyalomma detritum (5.70%), Hyalomma dromedarii (28.48%), Hyalomma marginatum (13.29%), Hyalomma schulzei (1.89%), Rhipicephalus bursa (3.16%) and Rhipicephalus sanguineus (3.16%), and for Takistan’s livestock were Hyalomma dromedarii (9.86%), Hyalomma marginatum (13.29%), Hyalomma schulzei (1.89%) and Rhipicephalus sanguineus (3.16%), respectively. Hard ticks compositions in different topographic areas were different. Hyalomma species had the most prevalence in the areas. Conclusions:The veterinary and public health investigation of the above species should be taken.

Field efficacy of siege gel bait in an IPM program on life stages of German cockroach (Blataria, Blattellidae) in a residential building.

Background: Current control strategies that rely on residual contact insecticides have resulted in insecticide resistance or tolerance to all the major groups of insecticides. New strategies are based on repeated monitoring, sanitation, educational programs and use of pesticides such as gel bait. Objective: Investigate the effectiveness of an Integrated Pest Management (IPM) program on life stages of German cockroaches at infested units of a residential building in southwestern Iran. Methods: Life stages (adult, nymph, and ootheca) of German cockroaches at 53 units (rooms) were monitored by sticky traps for eight months. The infested units were subjected randomly to IPM treatments and compared to controls following five weeks of monitoring. The IPM approach was based on an educational program using pamphlets, posters, lectures, sanitation with vacuuming, and application of hydramethylnon gel baits. Results: There was a high proportion of nymph population (76% of cockroach trap counts) before treatment. German cockroaches showed the highest frequency distribution in trap counts at surveyed residential units. Percentage reduction in nymphs was lower than the reduction in adults in the first week post treatment, although from the fourth to the twenty-sixth week, the percentage reduction was higher than in adults or equal when they reached 100% reduction. Mean total results showed significant reduction in adult and nymph stages throughout the treatment period. Reduction in ootheca fluctuated over the IPM program. Conclusion: Siege gel bait (Hydramethylnon 2%) in an IPM program successfully reduced adult and nymph stages of German cockroach infestation over the post treatment weeks especially after the fourth post treatment week.
