Leslie model for predatory gall-midge population
A Leslie matrix model for predatory gall-midge is constructed. From the model we estimate the stable age distribution which is important when the gall-midge is used in biological control. We compare the two common parametrizations of Leslie matrix., i.e. the flow-birth and the pulse-birth projections. We show that both parametrizations lead for the given data set to practically the same results...
متن کاملExperiments on chromosome elimination in the gall midge, Mayetiola destructor.
Cleavage in Cecidomyidae (Diptera) is characterized by the elimination of chromosomes from presumptive somatic nuclei. The full chromosome complement is kept by the germ-line nuclei. The course of cleavage in Mayetiola destructor (Say) is described. After the fourth division two nuclei lie in the posterior polar-plasm and become associated with polar granules, and fourteen nuclei lie in the res...
متن کاملThe gut transcriptome of a gall midge, Mayetiola destructor.
The Hessian fly, Mayetiola destructor, is a serious pest of wheat and an experimental organism for the study of gall midge-plant interactions. In addition to food digestion and detoxification, the gut of Hessian fly larvae is also an important interface for insect-host interactions. Analysis of the genes expressed in the Hessian fly larval gut will enhance our understanding of the overall gut p...
متن کاملGall Midge Olfaction and its Role in Speciation
With the swede midge (Contarinia nasturtii) as our main model species, we study two types of olfactory cues that are of importance for gall midges: 1) the pheromones emitted by the female to attract the male; 2) and the host plant volatiles that the females use when finding a host for oviposition. We found that both the blend of compounds and the enantioisomeric form are important for male attr...
متن کاملMorphological and Anatomical Studies of the Ovary Galls of Sesamum indicum l. Induced by the Gall Midge, Asphondylia sesami Felt
The organization of gall on the ovary ofSesamum indicum L induced by the gall midge, Asphondylia sesami Felt, not only affects biochemical equilibrium of the host but also causes disturbed vegetative growth and reduced seed-setting. The toxicity created by the gall maker induces the re-orientation of vasculature Cecidogenetic stimuli lead to excessive hypertrophy and hyperplasy forming the gall...
