“…They can cause damage to plants by curling and distorting their leaves, and stunting their shoots. They also cause severe indirect damage as vectors of plant viruses (Kennedy et al 1962;Raboudi et al 2002;Katis et al 2007). However, growers use mostly broad spectrum synthetic insecticides to manage aphids.…”

Effect of synthetic insecticides on the larvae of Coccinella septempunctata from Greek populations

et al. 2017

Coccinella septempunctata L. is one of the most abundant ladybird species in Greece, preying on several aphid species and other arthropods, of which many are pests of cultivated plants. These pests are usually controlled with chemical insecticides. During this process, however, beneficials are also exposed to pesticides. The development of Integrated Pest Management (IPM) programs against aphids requires the evaluation of the effects of insecticides on beneficial insects. We evaluated the LD 50 of imidacloprid, acetamiprid, bifenthrin and deltamethrin on first, second, third and fourth instar larvae of C. septempunctata by topical application. Moreover, we studied their sublethal effects (LD 10 ) on the development, weight and prey consumption of fourth instar larvae. The topical application bioassays showed that deltamethrin and bifenthrin were highly toxic to all larval instars, whereas imidacloprid and acetamiprid were less toxic to fourth instar larvae. The LD 10 dose significantly affected, developmental time, adult weight and daily predation. These results show the importance of assessing potential effect of insecticides on C. septempunctata for developing effective IPM programs of aphids in Greece.

“…This pest accounts for yield losses ranging from 37 to 90% (Abate et al, 2000;Ampofo and Massomo,2009). They cause impairment directly by sucking cell sap, secrete honeydew resulting in development of sooty mold on leaves and shoots and secondarily as vectors of certain plant viruses (Difonzo et al, 1997;Kennedy et al, 1962;Raboudi et al, 2002).…”

An extensive survey of aphid predatory Coccinellid beetles (Coleoptera: Coccinellidae) was conducted in Jahangirnagar University campus, Savar during October 2014 to March 2016. Total nine ladybird beetles viz, Adalia bipunctata, Coccinella septempunctata, Coccinella transversalis, Cycloneda munda, Harmonia axyridis, Hippodamia convergens, Micraspis discolor, Scymnus nebulosus, Sticholotis sp. were identified as predators of aphid. Among them, Micraspis discolor was most abundant predator. Biology and bio-control potential of M. discolor was studied in laboratory condition on bean infesting aphid (Aphis fabae). The maximum predation was 102±1.83 observed in 4 th instar larvae of M. discolor. Along with biological study, phylogenetic relationship of ladybird beetles was constructed based on mitochondrial COI gene. Out of nine identified coccinellids, five species showed more conserve region than the rest in alignment. The interspecific genetic distance ranges for nine beetles were very low (0.15-0.24). Higher interspecific genetic diversity recorded for H. axyridis. The phylogenetic tree was created and analyzed using both Neighbour Joining and Maximum likelihood methods to define the origin and evolutionary relationships of the species. Molecular analysis demonstrated that evolution of these species has been occurred from a common ancestor. Such study of ladybird beetles would be helpful in biological control program of aphid pest.

“…In addition to direct injury they can cause plants, aphids are able to transmit more than 200 plant viruses (Blackman and Eastop 2000). Apterous aphids can transmit viruses between adjacent plants and their alate offspring are often responsible for the transmission of viruses from one region to another (Raboudi et al 2002). The ability of aphids to transmit viruses is linked to their feeding exclusively on phloem sap (Sandström et al 2000).…”

The green peach aphid Myzus persicae Sulzer (Hemiptera, Aphididae) is an important pest of pepper, Capsicum annum (Solanaceae), with infestations by this aphid resulting in serious economic damage. Commonly, biological parameters are used to compare insect fitness on different varieties of pepper. Effect of rearing M. persicae on nine varieties of pepper (Anamex, Balconi, Bami, Chargui, Garn ghzel, Italico, J27, Starter and Torero) on the population density and percentage infestation it achieves, and its mean relative growth rate (MRGR) and generation time were studied under laboratory conditions. The highest population density, maximum percentage infestation (92.93%), minimum generation time (10.95 days) and highest MRGR (0.063) were recorded on the variety Chergui and the lowest population density, minimum percentage infestation (51.4%), minimum MRGR (0.043) and maximum generation time on the variety Anamex. For this, we need to know the behaviour of this aphid on different cultivated varieties of pepper in Tunisia and the susceptibility or resistance of these varieties to this aphid. This is a fundamental component of an integrated pest management program for any crop.In the present paper, the biological parameters of M. persicae reared under controlled conditions were studied in order to describe this aphid's behaviour on nine varieties of pepper. Materials and Methods Biological MaterialAphids were collected from a parthenogenetic population on pepper in a field at Chott Mariem in Tunisia (36°48ʹN, 10°11ʹE) and reared for several generations on sweet pepper in a green house at 21 ± 2 °C, HR: 60-80% and under a long day photoperiod (L:D 14:10) (Troncoso et al. 2005). These aphids were needed to infest the pepper plants used in the experiments.Nine varieties of Capsicum annum L. pepper (Anamex, Balconi, Bami, Chargui, Garn ghzel, Italico, J27, Starter and Torero) were used as host plants, which were established from seed sown in 12 cm diameter plastic pots filled with suitable soil. At the 8th leaf stage, plants were infested with M. persicae.
