Stage-specific surface chemicals of Plodia interpunctella: 2-acyl-1,3-cyclohexanediones from larval mandibular glands serve as cuticular lipids

Autor: Ralph W. Howard, James E. Baker

Publikováno v: Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology. 138:193-206

Cuticular lipid compositions of all life stages of the stored product moth Plodia interpunctella have been determined. Eggs and adults of P. interpunctella have cuticular lipids consisting solely of hydrocarbons. The composition of eggs and adult fem

Diatomaceous Earth Increases the Efficacy of Beauveria bassiana Against Tribolium castaneum Larvae and Increases Conidia Attachment

Autor: James R. Nechols, Jeffrey C. Lord, Ralph W. Howard, Waseem Akbar

Publikováno v: Journal of Economic Entomology. 97:273-280

This research tested the suppressive ability of Beauveria bassiana (Balsamo) Vuillemin alone and in combination with diatomaceous earth against the red flour beetle, Tribolium castaneum (Herbst). Adults did not show a dose response to B. bassiana, an

Mating Behavior of Cephalonomia tarsalis (Ashmead) (Hymenoptera: Bethylidae) and the Effect of Female Mating Frequency on Offspring Production

Autor: Ralph E. Charlton, Ralph W. Howard, Sonny B. Ramaswamy, Ling-lan Cheng, James F. Campbell, James R. Nechols

Publikováno v: Journal of Insect Behavior. 17:227-245

The courtship behavior of Cephalonomia tarsalis, a solitary semiectoparasitoid of Oryzaephilus surinamensis, was investigated in the laboratory. Courtship behavior includes a series of stereotypic movements. Males play the most active role, executing

Novel diterpenoids and hydrocarbons in the Dufour gland of the ectoparasitoidHabrobracon hebetor (Say) (Hymenoptera: Braconidae)

Autor: Ralph W. Howard, E. David Morgan, James E. Baker

Publikováno v: Archives of Insect Biochemistry and Physiology. 54:95-109

Chemical constituents contained in the Dufour gland of the ectoparasitoid Habrobracon hebetor (Say) (Hymenoptera: Braconidae) were characterized. Three terpenes, β-springene, a homo-β-springene, and a homo-geranyllinalool constitute approximately 3

Behavioral Interaction Between Males of Cephalonomia tarsalis (Ashmead) (Hymenoptera: Bethylidae) Competing for Females

Autor: Ralph E. Charlton, Sonny B. Ramaswamy, James F. Campbell, James R. Nechols, Ralph W. Howard, Ling-lan Cheng

Publikováno v: Journal of Insect Behavior. 16:625-645

Male Cephalonomia tarsalis (Ashmead) compete with one another for mates. The behavioral interactions between males for mates occur both on and off females. Males winning the first copulation do not exhibit apparent postcopulatory mate-guarding behavi

Cuticular hydrocarbons of the ectoparasitic waspCephalonomia hyalinipennis(Hymenoptera: Bethylidae) and its alternative host, the stored product pestCaulophilus oryzae(Coleoptera: Curculionidae)

Autor: Ralph W. Howard, Gabriela Pérez-Lachaud

Publikováno v: Archives of Insect Biochemistry and Physiology. 50:75-84

Cuticular hydrocarbons of an ectoparasitic wasp attacking two beetle hosts have been identified and examined for the influence of age, gender, mating status, and host on hydrocarbon composition. The 37 wasp hydrocarbons identified consisted of a seri
