Lack of Cry1Fa binding to the midgut brush border membrane in a resistant colony of Plutella xylostella moths with a mutaton in the ABCC2 locus

2012

ABSTRACT Previous studies reported “mode 1” Bacillus thuringiensis resistance in a colony of diamondback moths (NO-QA), and recently, this resistance has been mapped to an ABC transporter ( ABCC2 ) locus. We report the lack of binding of Cry1Fa to insects derived from this colony and compare our data with those from other insects with ABCC2 -associated resistance.

Neurosecretion in the Frontal Ganglion of the Stick Insect, Carausius morosus

1978

The presence of neurosecretory cells in the frontal ganglion (FG) has been demonstrated only in the Lepidoptera Bombyx (BOUNHIOL et al., 1953), Manduca (BORG et al., 1973; BELL et al., 1974), and Diatraea (YIN and CHIPPENDALE, 1975). In Manduca and Diatraea the neurosecretory material of the FG is apparently involved in the regulation of diapause.

Is Bactra bactrana (Kennel, 1901) a novel pest of sweet peppers?

2015

AbstractThis is the first report of Bactra bactrana (Kennel, 1901) (Lepidoptera: Tortricidae) attacking a major solanaceous crop, sweet pepper Capsicum annuum L. The infestation was detected in two greenhouses at the area of Tympaki (Southern Crete, Greece). The moth larvae caused typical symptoms of a fruit borer with numerous small holes on the surface of the peppers and extensive damage on the inside of the fruit as a result of the feeding activity. Unknown factors facilitated this major shift in host range since B. bactrana is typically a stem borer of sedges. In addition, the pest status of B. bactrana is currently under question, as in both cases the infestations by the moth were asso…

Vip3C, a novel class of vegetative insectidal proteins from Bacillus thuringiensis

2012

Three vip3 genes were identified in two Bacillus thuringiensis Spanish collections. Sequence analysis revealed a novel Vip3 protein class (Vip3C). Preliminary bioassays of larvae from 10 different lepidopteran species indicated that Vip3Ca3 caused more than 70% mortality in four species after 10 days at 4 οg/cm 2. © 2012, American Society for Microbiology.

Three New Species of the Bothriomirine Genus Leprocapsus Poppius from Indonesia (Hemiptera: Heteroptera: Miridae: Cylapinae)

2012

Abstract Three new species of the genus Leprocapsus Poppius from Indonesia, L. irianjayensis n. sp. and L. parvus n. sp. (Irian Jaya), and L. schuhi n. sp. (Sulawesi), are described. A color photograph of the adult and illustration of the antennal segments I and II of each treated taxa, dorsal habitus drawing of L. schuhi, illustration of the male genitalia of L. parvus, and scanning electron micrographs of selected structures of L. irianjayensis, L. schuhi, and L. scutellaris are provided. A key to all known species, diagnosis and the distribution map of the genus Leprocapsus are given.

Use of Bacillus thuringiensis toxins for control of the cotton pest earias insulana (Boisd.) (Lepidoptera: Noctuidae)

2006

ABSTRACT Thirteen of the most common lepidopteran-specific Cry proteins of Bacillus thuringiensis have been tested for their efficacy against newly hatched larvae of two populations of the spiny bollworm, Earias insulana . At a concentration of 100 μg of toxin per milliliter of artificial diet, six Cry toxins (Cry1Ca, Cry1Ea, Cry1Fa, Cry1Ja, Cry2Aa, and Cry2Ab) were not toxic at all. Cry1Aa, Cry1Ja, and Cry2Aa did not cause mortality but caused significant inhibition of growth. The other Cry toxins (Cry1Ab, Cry1Ac, Cry1Ba, Cry1Da, Cry1Ia, and Cry9Ca) were toxic to E. insulana larvae. The 50% lethal concentration values of these toxins ranged from 0.39 to 21.13 μg/ml (for Cry9Ca and Cry1Ia, …

The onset of metamorphosis in Tenebrio molitor larvae (Insecta, Coleoptera) under grouped, isolated and starved conditions

1991

Abstract The post-embryonic development of the beetle Tenebrio molitor presents a variable number of larval instars. Several parameters (instar length, time of apolysis and cuticle deposition) were compared during the larval-larval and larval-pupal cycles of mealworms over 50 mg, reared in grouped or isolated conditions. In grouped conditions comparable to mass breeding, larval-larval and larval-pupal apolyses were found to occur at the same time, but instar duration was longer in the case of prepupae. However, isolation was found to accelerate larval-pupal (but not larval-larval) apolyses and to reduce the number of larval instars, whereas starvation inhibited larval-larval (but not larval…

Investigating the origin of parthenogenesis and ploidy level in Dahlica fennicella (Lepidoptera: Psychidae)

2013

The theories for the predominance of sexual reproduction predict that parthenogens should have no long-term evolutionary potential due to the lack of genetic recombination, despite short term advantages. Although parthenogenesis is rare among high order animals, true parthenogens can be found in various taxa. The intriguing question of the proliferation and persistence of parthenogenetic species needs investigation. An ideal species for such research is a parthenogenetic mont Dahlica fennicella that appears to be as equally successful as other coexisting sexual species. We investigated whether high ploidy level of D. fennnicella is due to hybridization between closely related sexual species…
