[editar datos en Wikidata]

Diabrotica es un género de escarabajos de la familia Chrysomelidae. El género fue descrito por Chevrolat en 1837.

"Siempre, durante el transcurso de nuestro experimento, nos ha llamado la atención la extraordinaria voracidad de Diabrotica speciosa respecto a Cucurbita andreana [el zapallito amargo]. Sobre zapallitos amargos de unos 90 gramos, partidos por la mitad y dejados sobre el suelo, se llegaban a concentrar hasta 300 insectos por fruto. Lo que demuestra a las claras la posibilidad de utilizar esta especie como planta-trampa en la lucha contra esta plaga de las hortalizas." (Contardi 1939)[1]​

Tallamy et al. (2002)[2]​ trabajando en Estados Unidos hallaron la misma atracción de los frutos del zapallito amargo de Cucurbita andreana sobre la especie emparentada Diabrotica virgifera vigifera, plaga de maíz. Sus hallazgos, curiosos debido a que las cucurbitacinas que le dan el sabor amargo son tóxicas para la mayoría de los insectos,[cita 1]​ están en sintonía con los de otros autores que encontraron la gran atracción ejercida por las cucurbitáceas ricas en cucurbitacinas sobre los escarabajos crisomélidos de las tribus Diabrocitina y Aulacophorina[cita 2]​[cita 3]​[cita 4]​, que pueden detectarla desde largas distancias[cita 5]​[cita 6]​[cita 7]​ y las secuestran para su propia protección[cita 8]​[cita 9]​[cita 10]​

Se usan trampas contra estos insectos (utilizando como cebo la esencia floral de C. maxima simplificada),[cita 11]​ que se emplean hoy en día,[cita 12]​ si bien, como en los experimentos con zapallitos amargos cortados,[cita 8]​ el 99% de los insectos atraídos son machos[cita 13]​ que transfieren las cucurbitacinas a la hembra a través del espermatóforo y ella de allí a los huevos.

  2. ↑ Tallamy et al. (2005[3]​): (p.67) "For more than a century, researchers have noted the curious attraction of adult luperine chrysomelids in the subtribes Diabrocitina and Aulacophorina to cucurbit species rich in the bitter compounds collectivelly called cucurbitacins (Webster 1895,[6]​ Contardi 1939,[1]​ Metcalf et al. 1980[7]​)".
  3. ↑ Tallamy et al. (2005):[3]​ (p.72) "As discussed above, cucurbitacins are phagostimulants for many luperine adults (Metcalf et al. 1980,[7]​ Nishida and Fukami 1990,[8]​ Tallamy et al. 1997b[9]​) and larvae (DeHeer and Tallamy 1991[10]​)".
  4. ↑ Tallamy et al.̠ (2005[3]​) (p.70-71) "Cucurbitacins are produced in at least some tissues of all members of the Cucurbitaceae (Gibbs 1974,[11]​ Guha and Sen 1975,[12]​ Jeffrey 1980[13]​) and a few species in other plant families (Curtis and Meade 1971,[14]​ Pohlman 1975,[15]​ Dryer and Trousdale 1978,[16]​ Thorne 1981.[17]​) In most species they are concentrated in roots and fruits, with lesser amounts in stems and leaves. Because of their extreme bitterness, cucurbitacins are thought to be involved in plant protection against herbivores (Metcalf 1985,[18]​ Tallamy and Krischik 1989.)[19]​ Nevertheless, cucurbitacins are phagostimulants for both adults (Metcalf et al. 1980)[7]​ and larvae (DeHeer and Tallamy 1991[10]​) of several luperine species in the subtribes Aulacophorina and Diabroticina (Table 4.1) and can have important ecological consequences for plants that possess them (Tallamy and Krischik 1989[19]​). Adult luperines can detect cucurbitacins in nanogram quantities and readily devour bitter plant material (Metcalf 1994,[20]​ Tallamy et al. 1998.[21]​) In addition to WCR [western corn rootworm, Diabrotica virgifera virgifera], cucurbitacins influence the behaviour of several important crop pests, including Diabrotica balteata LeConte, the banded cucumber beetle, Diabrotica barberi Smith and Lawrence, the northern corn rootworm, Diabrotica undecimpunctata howardi Barber, the southern corn rootworm, and Diabrotica speciosa, a crop pest in Central and South America." Tabla 4.1 lista los insectos fagostimulados por cada cucurbitacina (incluye datos no publicados).
  5. ↑ Tallamy et al. (2005[3]​): (p.67) "[Diabroticina and Aulacophorina] can locate cucurbits over long distances by tracking flower and wound volatiles, and... cucurbitacins are phagostimulants for Diabroticites that... cause them to eat anything containing these compounds (Sinha and Krishna 1970,[22]​ Metcalf et al. 1980[7]​)."
  6. ↑ Tallamy et al. (2005[3]​): (p.81-82) "Electroantennogram (EAG) recording was used to identify extract compounds attractive to Diabrocites, citing: Hibbard et al. (1997b[23]​), Cossé and Baker (1999[24]​)."
  7. ↑ Tallamy et al. (2005[3]​): (p.82) "As noted above, despite specialization on the Poaceae, adult WCR [western corn rootworm, Diabrotica virgifera virgifera] and D. barberi feed compulsively on bitter cucurbitacins when presented the opportunity, and they are attracted to volatiles from Cucurbita blossoms (Metcalf and Metcalf 1992[25]​ and references therein)."
  8. ↑ a b Tallamy et al. (2005[3]​): (p.71-72). "Studies have shown that, when WCR [western corn rootworm, Diabrotica virgifera virgifera] eat crystalline cucurbitacins for 2 days, they excrete 85% of the material and permanently sequester the remainder in their fat bodies, cuticles, haemolymph, spermatophores and developing eggs (Ferguson and Metcalf 1985,[26]​ Andersen et al. 1988,[27]​ Tallamy et al. 2000).[28]​ There is good evidence that, regardless of the cucurbitacin configuration eaten, beetles transform it through glycosilation, hydrogenation, desaturation and acetylation into 23,24-dihydrocucurbitacin D (Andersen et al. 1988,[27]​ Nishida et al. 1992.)[29]​ There are decided defensive benefits to cucurbitacin sequestration. Beetles that have eaten cucurbitacins become highly distasteful and are readily rejected by predators such as mantids, mice and finches (Ferguson and Metcalf 1985,[26]​ Nishida and Fukami 1990,[8]​ DW Tallamy, unpublished data). Sequestered cucurbitacins may also discourage parasitoids such as tachinid flies in the genus Celatoria, although this has never been tested. Moreover, when cucurbitacins have been sequestered in eggs and larvae, both of which are denizens of pathogen-rich damp soil, survival after exposure to the entomopathogen Metarhizium anisopliae is significantly improved (Tallamy et al. 1998[21]​). This may explain why females shunt 79% of the cucurbitacins that are not excreted into their eggs or the mucus coating of the eggs (Tallamy et al. 2000[28]​)."
  9. ↑ Tallamy et al. (2005[3]​): (p.73) "Luperines [Chrisomelidae] such as WCR [western corn rootworm, Diabrotica virgifera virgifera], have been described as pharmacophagous insects (Nishida and Fukami 1990[8]​) because they search for particular phytochemicals for purposes other than primary metabolism or host recognition (Boppré 1990[30]​)."
  10. ↑ Tallamy et al. (2005[3]​): (p.73) "Whether obtained through pharmacophagy or specialization on cucurbits, cucurbitacins persist in the cuticle, fat bodies and haemolymph (Ferguson et al. 1985,[31]​ Andersen et al. 1988[27]​) and provide protection against predators (Ferguson and Metcalf 1985,[26]​ Nishida and Fukami 1990[8]​) and/or pathogens (Tallamy et al. 1998.[21]​) Perhaps because of their defensive benefits, both cucurbitacins and pyrrolizidine alkaloids have also become an integral component of the reproductive behaviour of participating species (Dussourd et al. 1991,[32]​ LaMunyon and Eisner 1993,[33]​ Tallamy et al. 2000).[28]​ In both cases, the pharmacophagous agent is consumed directly by females and/or is sequestered by males and passed whithin spermatophores to females. Females, in turn, shunt the majority of these materials to developing eggs".
  11. ↑ Tallamy et al. (2005[3]​): (p.81) "Diabrotica spp., in general, have been associated with blossoms of varying Cucurbita spp. (Fronk and Slater 1956,[34]​ Howe and Rhodes 1976,[35]​ Bach 1977,[36]​ Fisher et al. 1984[37]​). Andersen and Metcalf (1987[38]​)... (found they preferred C. maxima over the other species)" (p.81) "Andersen (1987[39]​) identified 22 of the 31 major components of C. maxima floral aroma. Metcalf and Lampman (1991[40]​ and references therein) evaluated them for attraction to diabroticite beetles... Metcalf and Metcalf (1992[25]​ and references therein) (developed a 3-component blend as a highly simplified Cucurbita blossom volatile aroma). (p.83) "Metcalf and Metcalf (1992[25]​)... added a methoxy group to natural compounds (that) dramatically increased its effectiveness in attracting adult beetles.... It is these more attractive methoxy analogues of natural compounds which are generally used as lures today".
  12. ↑ Tallamy et al. (2005[3]​): (p.83-84-85) it mentions some real lures and if they are commercially availables, the most effective a new trap developed by Trécé (Salinas, California) containing buffalo gourd root powder.
  13. ↑ Tallamy et al.: (2005[3]​) (p.72)"Despite the benefits to female WCR [western corn rootworm, Diabrotica virgifera virgifera] from eating bitter cucurbit tissues, it is males rather than females who actively seek these compounds in nature. In a field trial quantifying the sex ratio of beetles that came to cucurbitacin-rich fruits of Cucurbita andreana, Tallamy et al. (2002[2]​) found that 99% of the 224 WCR [western corn rootworm, Diabrotica virgifera virgifera] found at the fruits over a 5-day period were males. This result concurs with the male-biased sex ratios frequently found in cucurbitacin traps (Shaw et al. 1984;[41]​ Fielding and Ruesink 1985[42]​). Apparently females rely on males for their primary source of cucurbitacins (Tallamy et al. 2000[28]​). Males sequester 89% of the cucurbitacins not excreted after ingestion in their spermatophores and pass them to females during copulation. Whether such behaviour imparts a mating advantage to WCR [western corn rootworm, Diabrotica virgifera virgifera] males has not been investigated."
