The mint rhizome borer, Datonychus melanostictus (Marsham, 1802), is a new pest of spearmint crop in Chaouia region north central of Morocco. The main damage is caused by the larvae, which tunnel inside the rhizomes. In this study, we investigated the population fluctuation of D. melanostictus in spearmint fields during two seasons 2013 and 2014 using two sampling methods. The emergence of weevil begins in late March, followed by an increase of egg laying activity during May. A strong larval activity takes place at rhizomes below ground during late May to early June. Pupation takes place mainly inside the rhizomes. New generation adults reached three peaks between June and early August 2013 and two peaks during June and July in 2014. The highest larval density recorded before flowering resulted in significant reduction of the average fresh yields to 6.6 t/ha. Protection of mint fields against D. melanostictus is a daily challenge, population dynamics can be a tool to predict and to help farmers for applying protection methods in the best way.

Chickpea Leaf miner, Liriomyza cicerina Rond., behavior was investigated regarding the oviposition preference and insect performance. In choice situation, the insect was able to discriminate among the presented cultivars of chickpea and showed an oviposition preference. The resistant and the susceptible plants had the lowest and highest number of eggs per plant, respectively. In the no-choice test, the insect laid fewer eggs on the improved lines and oviposition was significantly correlated to the insect performance in terms of larval survival and adult emergence. In both the choice and no-choice tests, oviposition was also correlated with the leaf surface area. The female incentive to produce eggs was affected by the presented plants as they laid more eggs in the presence of susceptible plants. High attraction for oviposition could be used in attract-and-kill pest management designs.

Tomato production plays an important role in Burkina Faso by contributing to food security and increasing farmers’ income. However, this crop is susceptible to several pests among which Tetranychus evansi Baker and Pritchard is of economic importance. The present study carried out in the commune of Yako, an important tomato production area in northern Burkina Faso, aims to evaluate the outcome of combining a bioacaricide (Biopiq) from plant origin with sprinkler irrigation in the view of an integrated control of T. evansi in tomato irrigated crops. The experimental design consisted of six treatments in four replications including sprinkler irrigation, gravity irrigation, Acarius (abamectin-based commercial acaricide used as positive control) and Biopiq (plant-based acaricide) sprayings and the combination of each acaricide with both irrigation techniques. Observations made from tomato transplanting to harvest included T. evansi density/ leaf, plant infestation levels, leaf damage index, plant production parameters such as numbers of leaves, flowers and fruits and yield assessment. Results showed that the combination of Acarius and Biopiq with sprinkler irrigation significantly reduced density and damage caused by T. evansi. These treatments also produced similar and significantly higher yields (14,875±1,982 kg/ha; 14,687±924kg/ha respectively) compared to other treatments. These results lead to promising prospects for the control of T. evansi in irrigated tomato crops in West Africa. The strategies for an optimal use of these findings on a large scale through an integrated management approach remain to be defined.

After the ban on treating oilseed rape seeds with neonicotinoids in European Union, cabbage stem flea beetles (Psylliodes chrysocephala Linnaeus, 1758) again became one of its main pests. In Czechia, the impact of this pest increases every year, given with the narrowing spectrum of suitable insecticides and growing damage to oilseed rape plants in autumn. Based on this scenario, it is appropriate to look for alternative options to control oilseed rape pests. One option could be supporting beneficial organisms. One of these organisms is the hymenopteran braconid parasitoid Microctonus brassicae (Haeselbarth, 2008), which parasitizes adult cabbage stem flea beetles. Its occurrence has now been confirmed outside Great Britain in Czechia and continental Europe respectively. Five male specimens of M. brassicae emerged from 50 collected adults of cabbage stem flea beetle by sweep netting from two localities in central Bohemia. This parasitoid of adult cabbage stem flea beetles and its larval parasitoids probably play an important role in the life cycle and population dynamics of this pest. Current knowledge about the biology, taxonomic classification and identification of this parasitoid is summarized in this paper.

Blattella germanica (L.) (Blattodea: Blattellidae) is one of the major household pests worldwide, commonly named German cockroach. Application of gel baits is one of the most efficient management methods. This study investigated the effect of 3 commercially available Imidacloprid gel baits on the palatability of dead cockroaches and, consequently, on the efficacy of secondary killing. German cockroaches killed by the gel baits and others killed by freezing were offered to conspecifics, the numbers of cannibalistic cockroaches and dead cockroaches, as well as weight loss were recorded. Despite the content of Imidacloprid is identical in all the baits, the palatability of the cockroach killed by the gel consumption and used as food was different between the 3 commercial products, with consequences on the secondary killing effect. These results suggest as the bait co-formulants play an important role not only on the palatability of the bait but also in the palatability of the dead cockroaches which are eaten by conspecifics, and therefore, in the result of a pest control application.

Mosquitoes have always played an important role in transmitting a wide range of viral and parasitic diseases to humans and animals. Given that so far there has been no study on the fauna, distribution and characteristics of mosquito habitats in Qir and Karzin County, we decided to investigate these unknown data in this important tropical area in south of Iran for the first time. Adult mosquitoes were collected by hand-catch and total catch methods from indoor and outdoor places in Qir and Karzin Counties from four different geographical regions during the activity seasons of mosquitoes in 2017-18. Also, larvae were collected from aquatic habitats using WHO recommended standard dipper. Collected mosquitoes were identified using valid taxonomic keys. A total of 1884 specimens of Culicidae mosquitoes (1103 adults and 781 larvae) were collected from twenty-one sampling areas during the mosquito activity seasons in Qir and Karzin County. Totally 11 species in 3 genera (7 Culex, 3 Anopheles and 1 Culiseta species) were identified. The dominant larva was Cx. laticinctus with a total number of 227 (29%), and Cx. sinaiticus with 407 specimens (36.9%) which was the most frequent adult mosquito. Most larval habitats in this area were sunny and almost without vegetation breeding sites with temporary, turbid and stagnant water. In this region, compared to the area of the County, there was considerable species diversity for mosquitoes. This phenomenon is very important from an ecological and health point of view. Due to the existence of some important vectors of arthropod-borne diseases in this region, the health system should be alert and continuous and accurate monitoring of these vectors should be included in the routine vector-borne diseases control program.

This research aims to study the efficacy of Cinnamomum verum (Cv) extracts for ovicidal, larvicidal, and repellent activities against Culex quinquefasciatus mosquito vectors. The active components of C. verum or cinnamon oil by Gas Chromatography (GC) analysis showed the highest cinnamaldehyde at 83.53%. For ovicidal assay, C. verum essential oil at concentrations 12.5, 25 and 50 ppm at 72 h had 100% egg hatch inhibition and had a significant difference when compared to the control group (p<0.05). Larvicidal activity showed that concentrations of 25 and 50 ppm were highly effective in killing 100% mosquito larvae. Morphological changes in egg raft showed a faded color and eggs that seemed to have split from their raft while the larvae changed to a pale white wrinkled body with a destroyed inner tube of the body and were motionless. A Scanning electron microscope study showed that the eggshell and micropyle were wrinkled with the chitin peeled out. After treatment with cinnamon oil, larvae appeared to have a wrinkled body, the thorax and abdominal cuticle were also destroyed with high density of oil particles observed on mouth brushes and obstructing the spiracle. The repellent assay showed that cinnamon oil could repel both male and female mosquitos for up to 180 min. From the results, it was concluded that cinnamon oil had highly effective repellency against Culex quinquefasciatus adults and insecticidal activity on eggs and larvae stages evidenced by LC50 at 6.59±0.54, 9.07±0.67 and 36.91±7.56 ppm and its morphological changes indicated how the mosquito could not survive after cinnamon oil treatment hence this may be a useful alternative method that is green friendly for controlling mosquitoes in endemic areas.

The active components of C. verum or cinnamon oil by Gas Chromatography (GC) analysis showed the highest cinnamaldehyde at 83.53%. For ovicidal assay, C. verum essential oil at concentrations 12.5, 25 and 50 ppm at 72 h had 100% egg hatch inhibition and had a significant difference when compared to the control group (p<0.05). Larvicidal activity showed that concentrations of 25 and 50 ppm were highly effective in killing 100% mosquito larvae. Morphological changes in egg raft showed a faded color and eggs that seemed to have split from their raft while the larvae changed to a pale white wrinkled body with a destroyed inner tube of the body and were motionless. A Scanning electron microscope study showed that the eggshell and micropyle were wrinkled with the chitin peeled out. After treatment with cinnamon oil, larvae appeared to have a wrinkled body, the thorax and abdominal cuticle were also destroyed with high density of oil particles observed on mouth brushes and obstructing the spiracle. The repellent assay showed that cinnamon oil could repel both male and female mosquitos for up to 180 min. From the results, it was concluded that cinnamon oil had highly effective repellency against Culex quinquefasciatus adults and insecticidal activity on eggs and larvae stages evidenced by LC50 at 6.59±0.54, 9.07±0.67 and 36.91±7.56 ppm and its morphological changes indicated how the mosquito could not survive after cinnamon oil treatment hence this may be a useful alternative method that is green friendly for controlling mosquitoes in endemic areas.","PeriodicalId":37777,"journal":{"name":"Journal of Entomological and Acarological Research","volume":"53 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47714268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
