“…Their pest status (fifteen species and subspecies are reported as pests of sixty‐one different crops (Krysan, 1986)), has meant that Diabrotica species have been the focus of numerous studies on life history (Metcalf, 1979; Branson & Krysan, 1981; Krysan, 1982), species distribution (Smith, 1966; Krysan, 1986; Krysan & Smith, 1987), reproductive isolation (Krysan & Guss, 1978; Krysan et al. , 1983, 1986; Guss et al. , 1982, 1983a, 1983b, 1984, 1985; Giordano et al.…”

Meinke, Lance J.; and Foster, John E., "Molecular phylogeny of Diabrotica beetles (Coleoptera: Chrysomelidae) inferred from analysis of combined mitochondrial and nuclear DNA sequences" (2001). Faculty Publications: Department of Entomology. 633. http://digitalcommons.unl.edu/entomologyfacpub/633 AbstractThe phylogenetic relationships of thirteen Diabrotica (representing virgifera and fucata species groups) and two outgroup Acalymma beetle species (Coleoptera: Chrysomelidae) were inferred from the phylogenetic analysis of a combined data set of 1323 bp of mitochondrial DNA (mtDNA) cytochrome oxidase subunit 1 (COI) and the entire second internal transcribed spacer region (ITS-2) of nuclear ribosomal DNA of 362 characters. Species investigated were D. adelpha, D. balteata, D. barberi, D. cristata, D. lemniscata, D. longicornis, D. porracea, D. speciosa, D. undecimpunctata howardi, D. u. undecimpunctata, D. virgifera virgifera, D. v. zeae, D. viridula, and outgroup A. blandulum and A. vittatum. Maximum parsimony (MP), minimum evolution (ME), and maximum likelihood (ML) analyses of combined COI and ITS-2 sequences clearly place species into their traditional morphological species groups with MP and ME analyses resulting in identical topologies. Results generally confer with a prior work based on allozyme data, but within the virgifera species group, D. barberi and D. longicornis strongly resolve as sister taxa as well as monophyletic with the neotropical species, D. viridula, D. cristata and D. lemniscata also resolve as sister taxa. Both relationships are not in congruence with the prior allozyme-based hypothesis. Within the fucata species group, D. speciosa and D. balteata resolve as sister taxa. Results also strongly supported the D. virgifera and D. undecimpunctata subspecies complexes. Our proposed phylogeny provides some insight into current hypotheses regarding distribution status and evolution of various life history traits for Diabrotica.

“…The WCR sex pheromone was the first to be identified and synthesized from a chrysomelid (Guss et al , 1982), although the first evidence of pheromone use by a chrysomelid came from the banded cucumber beetle Diabrotica baleata LeConte (Cuthbert & Reid, 1964). The same molecule is also the active component of the sex pheromone of the Mexican corn rootworm Diabrotica virgifera zeae (MCR); the two closely‐related sub‐species (Krysan et al , 1980) have nearly identical response profiles to the pheromone (Guss et al , 1984). The NCR also uses 8R‐methyl‐2R‐decenyl‐propanoate (8R,2R) as its sex phermone (Guss et al , 1982; Dobson & Teal, 1987).…”

1 The western corn rootworm (WCR) is a historic pest with a legacy of resistance and behavioural plasticity. Its behaviour and nutritional ecology are important to rootworm management. The success of the most effective and environmentally benign rootworm management method, annual crop rotation, was based on an understanding of rootworm behaviour and host -plant relationships. Enthusiastic adoption of crop rotation, provided excellent rootworm management, but also selected for behavioural resistance to this cultural control. 2 Though well-studied, significant gaps in WCR biology remain. Understanding the topics reviewed here (mating behaviour, nutritional ecology, larval and adult movement, oviposition, alternate host use, and chemical ecology) is a starting point for adapting integrated pest management and insect resistance management (IRM) to an expanding WCR threat. A presentation of significant questions and areas in need of further study follow each topic. 3 The expansion of WCR populations into Europe exposes this pest to new environmental and regulatory conditions that may influence its behaviour and ecology.Reviewing the state of current knowledge provides a starting point of reference for researchers and pest management decision-makers in North America and Europe. 4 The trend toward increasing adoption of transgenic maize will place an increasing premium on understanding WCR behaviour. IRM plans designed to promote sustainable deployment of transgenic hybrids are grounded on assumptions about WCR movement, mating and ovipositional behaviour. Preserving the utility of new and old management options will continue to depend on a thorough understanding of WCR biology, even as the ecological circumstances and geography of WCR problems become more complex.

“…34 This compound is also attractive to several Diabrotica species. 35,36 Males of D. virgifera virgifera and D. virgifera zeae responded to (2R,8R)-and (2S,8R)-7, while D. porracea responded exclusively to (2S, 8R)-7. Only the (2R, 8R)-7 was attractive to the northern corn rootworm, D. barberi.…”
