Leaf cutting ants

The Barton-Zard pyrrole synthesis has now been extensively applied to synthesis of natural and unnatural products containing pyrrole units. Methyl 4-methylpyrrole-2-carboxylate is the trail-maker pheromone of the Texas leaf-cutting ant Atta texana.24 It is readily prepared by the Barton Zard method in 60% yield (Eq. 10.22).22... [Pg.331]

Leaf-cutting ants cause no direct damage to bananas, but they are a constant threat to the plantation. They build their nests in river levees and the underground tunneling renders the structure ineffective against rising water. Chlordan is an effective insecticide when all openings to the nest can be treated. [Pg.76]

The title ketone (S)-4, which is 400 times more active than its optical antipode,6 is the principal alarm pheromone of the leaf cutting ant Atta texana. (S)-4 has also been identified as an alarm pheromone 1n three other ant genera of the subfamily Mymioinae,6 9 as a component of the defensive... [Pg.243]

Uses Mirex is used in North America and in the southeastern United States for the control of fire and ants. Mirex is also effective against the hamster ant, the yellow-jacket, the Texas leaf-cutting ant, and the Hawaiian mealy bug. A ban on the use of mirex for pest control with exemptions was brought in on June 30, 1978. It has its use as a fire retardant in plastics, rubber, paint, paper, and electrical goods from 1959 to 1972 due to its high melting point and high chemical stability.14,48... [Pg.113]

The synthetic utility of the SAMP/RAMP hydrazone method is demonstrated in particular in the stereoselective alkylation of aldehyde and ketone SAMP/RAMP hydrazones. A great number of natural products have been synthesized using this method, like the principal alarm pheromone of the leaf cutting ant Atta texana (eq 1), the C(l)-C(15) segment of FK 506 (eq 2) the amino acid MeBMT (eq 3), and (-)-methyl kolavenate (eq 4). ... [Pg.32]

Projects relating to the use of bioproducts have been conducted in our laboratory at the Federal University of Sao Carlos in Brazil. Three main projects can be mentioned. The first involves studies on the potential of certain plant species to produce natural products for the control of leaf-cutting ants. The second is on the theme of phytochemistry and chemical ecology, and concerns the search for model eompounds for the development of new insecticides, fungicides and bactericides to control plant pests. And the third concerns a search for antiparasitic natural products. [Pg.178]

Most social insects use alarm and trail pheromones. Their specificity is not so important, but fast release and dispersal are important. They tend to be small volatile substances for instance, (S)-4-methyl-3-heptanone is an alarm pheromone in the leaf-cutting ant, Atta textata. [Pg.149]

Another example of natural product symbiosis in insects is found in leaf-cutting ants of the tribe attini (see Chapter 2.04). The insects collect fresh leaves as nutrient source for a fungus that they cultivate within their... [Pg.495]
