Seed Introduction

Abstract Ascochyta blight is the most severe disease of cool-season pulses (Davidson and Kimber, 2007). D. fabae (anamorph: Ascochyta fabae) attacks Vicia faba and can survive and reproduce in and spread from crop debris or be transported in infected seed. Introduction on infected seed occurred in Australia and Canada in the 1970s, and was probably the means for the pathogen's original spread to countries outside southwestern Asia. Ascospores are disseminated by wind from the debris as primary inoculum and secondary cycles are initiated by conidia spread by rain splash from plant lesions. The fungus is host-specific in causing disease, but may be able to survive in non-host plants and reproduce on their debris. It is not treated as a phytosanitary risk or listed as an invasive pathogen by major organizations. Seed certification is the primary means of preventing its spread to new areas and the importation of new genotypes of the fungus to areas already infested.

Leguminous Host

A total of 28 species of agromyzid flies belonging to 7 genera have been reared and described on 34 different leguminous host -plants from Pantnagar, Nainital, Northern India. 13 agromyzid flies have been described as new species viz., Japanagromyza species nova (sp.n.) ex leaves of Pueraria phaseoloides (Roxb.) Benth; Liriomyza sp.n. ex leaves of Vicia sativa Linn.; Liriomyza sp.n. ex leaves of Vicia faba Linn.; Malanagromyza sp.n. ex stems of Cassia sp.; Melanagromyza sp.n. ex stems of Pisum sativum Linn. Melanagromyza sp.n. ex stems of Trifolium pratense Linn.; Melanagromyza sp.n. ex stems of Vicia faba Linn.; Ophiomyia sp.n. ex stems of Pueraria Phaseoloides (Roxb.) Benth; Ophiomyia sp.n. ex stems of Sesbania aculeata Pers.; Ophiomyiz sp.n. ex stem of Vigna mungo (Linn.) Heeper and Ophiomyia sp.n. ex stems of Vigna mungo (Linn.) Heeper. Large numbers of host plants have been recorded as new host for various agromyzid species. More than one thousand male genitalia slides have been prepared for this study. Variations in morphology and genitalia characters have also been illustrated within the species. DOI: http://dx.doi.org/10.3126/njbs.v1i0.7474 Nepalese Journal of Biosciences 1: 66-82 (2011)

1. A new species of aphis, Aphis (Doralis) cognatella, found on Euonymus europaeus is described and compared with Aphis (Doralis) fabae, which it closely resembles. This new aphis is brown in colour and has long hairs.2. Two individuals, intermediate in character between oviparae and sexuparae, are mentioned.3. Transference experiments, carried out under somewhat artificial conditions, show that although the aphis is normally found on Euonymus sp., it can exist for some time on Rumex obtusifolius, R. crispus, Chenopodium album, Capsella bursapastoris, Arctium lappa, and Beta vulgaris (flower stalks), which are also host plants of A. fabae, but it does not colonise Vicia faba.4. The sexuparae are apterous and produce males, oviparae and apterae, thus differing from A.fabae, in which there are two sexuparous forms, one an alate gynopara and the other an apterous form found on the summer hosts.5. Olfactometer experiments give no indication of any olfactory response to the odour of E. europaeus leaves.

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). [...]
