Aphis Craccivora Koch

The Aphids, Aphis craccivora (Koch) is a serious pest in agricultural fields in Egypt. Entomopathogenic fungi are biological control agents of insects. The study was carried out on the aphid by using of Bio Catch, Verticillium lecanii, Bio Power, Beauveria bassiana and Bio Magic, Metarhizium anisopliae on A. craccivora. Laboratory experiments were done to measure the pathogenicity of three commercial compounds from entomopathogenic fungi, Bio Catch, V. lecanii, Bio Power, B. bassiana, and Bio Magic, M. anisopliae against adults and nymphs of A. craccivora. Three concentrations were used from all compounds, 107 , 108 and 109 spores/ml. at 22 ± 2°C and 75 ± 5 R.H. The concentration (109 spores/ml.) gave 100% mortality with V. lecanii and B. bassiana then M. anisopliae. The Lowest LC50 value of 2.1 x 106 spores/ml. was recorded by V. lecanii, which showed higher virulence compared to other entomopathogenic fungi. The LC50 values of V. lecanii, B. bassiana and M. anisopliae were 2.1 x 106 , 4.3 x 106 and 6.4 x 107 spores ml., respectively. At the highest concentration of 109 spores/ml., the Median LT50 values for V. lecanii, B. bassiana and M. anisopliae were 4.2, 5.2 and 7.0 days, respectively.

Host Associations

An investigation of host associations, distribution and types of reproduction (sexual, asexual) of Lysiphlebus fabarum (Marshall) across 20 provinces of Iran during 2006-2011 was undertaken. The parasitoid was reared from three groups of host aphids belonging to genera Aphis and Brachycaudus, and occasional host aphid genera. Aphis craccivora Koch was the most frequent host aphid for L. fabarum on various host plants, including economically important crops. The field sex ratio generally favored females, but in some cases, only thelytokous (uniparental) populations were found. In those cases, the host was always an Aphis species. Specimens reared from Brachycaudus aphids were all biparental, indicating the presence of a sibling biological species. Overall analysis of diagnostic morphological characters in the forewing indicated intra-specific variability in forewing marginal setae as well as variations in length of the R1 vein.

In the late 1970s, Brazilian peppertree, Schinus terebinthifolia Raddi (Sapindales: Anacardiaceae), was targeted for classical biological control in Florida because its invasive properties (see Host Plants) are consistent with escape from natural enemies (Williams 1954), and there are no native Schinus spp. in North America. The lack of native close relatives should minimize the risk of damage to non-target plants from introduced biological control agents (Pemberton 2000). [...]
