We report the first record of Neochrysocharis formosa (Westwood) parasitizing larvae of the tomato moth, Tuta absoluta (Meyrick), in tomato crops in Northern Buenos Aires Province, Argentina. Tomato moth larvae were sampled during four consecutive growing cycles, between 2003 and 2005, in 10 sites. Neochrysocharis formosa was present only in organic ...

The tomato moth, Tuta absoluta Meyrick, is one of the most important tomato pests in South America. In Argentina, management strategies include only chemical control. In this work, the parasitoid wasp Trichogrammatoidea bactrae Nagaraja was evaluated as a potential natural enemy against this pest. Biological and population parameters were estimated by ...
Tuta absoluta (Meyrick) is an important tomato pest that also feeds on other host-plants from the Solanceae family. We studied the effect of two cultivated plants, tomato (Lycopersicum esculentum Mill.) and potato Solanum tuberosum L. on the development and populational parameters of T. absoluta related with host-plant suitability. ...
Insecticide plants are an important tool among the new alternatives for pest control in IPM systems because they reduce the use of synthetic insecticides, preserving human health and the environment. We investigated the effects of aqueous extracts of Melia azedarach leaves and Azadirachta indica seeds and three tomato genotypes, 'Santa Clara', 'IPA-5'--Solanum lycopersicum (=Lycopersicon ...
We examined the interaction between the tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), a key pest of tomato crops in South America, and its main solitary larval parasitoid, Pseudapanteles dignus (Muesebeck) (Hymenoptera: Braconidae). The pattern of parasitism of T. absoluta by the parasitoid was studied at three ...
Laboratory studies were conducted to measure selected life history traits and the functional response of the parasitoid Pseudapanteles dignus (Muesebeck), a major enemy of Tuta absoluta (Meyrick) in tomato crops in South America. Newly mated P. dignus females were individually exposed to 10 host larvae in mines for 24 h. We determined developmental time ...
The subject of this work concerns with the measurement of absolute calibration factors for the use of CR-39 as an absolute detector in indoor daughters monitoring. Up to now the usefulness of calibration factors was restricted to environmental conditions ...

The presence of Stigmella epicosma (Meyrick) is reported for the first time from two coastal valleys from northern Chile: Azapa and Chaca. Adults examined were reared from leafminer larvae on Trixis cacalioides (Asteraceae), the first host plant known for S. epicosma. PMID:21437500
Eriocydia Razowski & Brown, new genus, is described to accommodate the single species Laspeyresia guttifera Meyrick, 1913. Most recently the species was placed in Cydia (Grapholitini); however, several morphological features contradict its assignment to not only to Cydia but to Grapholitini. Eriocyd...

It is a classical result of Postnikov [15] that homotopy types X with at most two non-trivial homotopy groups [pi]mX = A and [pi]n<EM>X> = <EM>B>, 2 [less-than-or-eq, slant] <EM>m> < <EM>n>, are classified by the ...
The theory of reductive monoids has been well developed by Renner and the author, cf. [8, 13]. This paper concerns the finite reductive monoids MF where M is a reductive monoid and F[ratio]MEM>[rightward arrow]<EM>M> is a Frobenius map. We show that the Deligne-Lusztig characters ...
