Aromatic Herbs

Colombian aromatic herbs have great potential as an export commodity. The genus Copitarsia is considered as an economic and a quarantine pest attacking them. In herbivore insects, host plant choice is made by adults and influenced by host plant quality. There were performed olfactory and feeding tests by using four-arm olfactometer and offering four different aromatic herbs (basil, mint, rosemary, or thyme) to determine the host selection behavior of Copitarsia uncilata Burgos and Leiva. Parameters, such as adult choice, larval weight, and time spent by larva on particular herb were measured. The preferences of adults and immature of C. uncilata varied significantly among the herbs in olfactory and larva feeding tests. The adults showed significantly higher responses to essential oils of basil and rosemary. Higher weight of larva was recorded on mint and basil. Further studies on larval development and longevity of adults on different herbs are necessary.

Host Plant Relationships

The biosystematic position of the Parallelia generic complex is reviewed and a revised generic classification of its component taxa is presented. Bastilla Swinhoe (= Xiana Nye, syn. nov., Naxia Guenée, syn. nov.) is identified as the most appropriate genus for a large number of these taxa, including the joviana-group, which is reviewed in detail, with description of two new species, B. nielseni, sp. nov. and B. binatang, sp. nov. Parallelia prouti Hulstaert, syn. nov. and P. cuneifascia Hulstaert, syn. nov. are recognised as junior synonyms of Bastilla vitiensis Butler and two newly described Tahitian taxa are transferred into the joviana-group. Larval host records are examined in relation to this new generic system and significant preference for the Euphorbiaceae is noted for several groups: Bastilla, Buzara Walker (= Caranilla Moore, syn. nov., another segregate from Parallelia) and an Australian group within Grammodes Guenée.

AbstractDuring initial screening of the synthetic pyrethroid lamdacyhalothrin (PP 321) at a concentration of 44 and 22 mg/l and applied as a 30 ml drench over each plant against third to fourth instar cutworms, Agrotis segetum (Denis & Schiffermüller) in microplots, few died but they did not damage the plants. Reducing the concentrations to 11 and 5.5 mg/l increased mortality and plant damage. When A. segetum were confined on soil treated with the insecticide at concentrations of 22, 11 and 5.5 mg/l and sprayed at an equivalent rate of 500 l/ha, they all died within one day. The higher concentrations appeared to have a repellent and/or antifeedant effect, and it has been possible to reduce the concentration of lamdacyhalothrin to 12.5 mg/l (≡5.6g a.i./ha) for the drench treatment without risking economic plant damage. For insecticides that have repellent and/or antifeedant properties, it should be possible to balance lower concentrations with adequate protection of plants from pest damage.
