Progress Report on Funnel Ant Control
نویسنده
چکیده
The funnel ant, Aphaenogarter pyllzia Forel, infests several hundreds of acres in each of the mill areas of Mossman, Rambledon, Mulgrave and Tully, is present to a lesser extent in the Innisfail, Ingham, Proserpine and Mackay districts and has been recorded in a few minor infestations at Bundaberg. In the first-named four areas, each year a few farms are added t o the list of those known to be infested, but it is probable that the additional records arise from an increasing awareness of the pest on the part of canegrowers rather than from any appreciable spread of actual infestation. While plant cane occasionally suffers diminished yield due t o the ants, the major losses occur i~ ratoons, in the form of reduced growth and patches of complete ratoon failure. The effect on the cane is attributed to the insects' habit of tunnelling the soil extensively, leading to over-aeration, loss of moisture and separation of the roots from the soil; also, it is due to some direct root injury by the ants, which have been observed, in cages, to lacerate roots and feed on the sap.

Ant-induced Alopecia: Report of two cases
Localized scalp hair loss has different causes which alopecia areata, trichotillomania, tinea capitis and early lupus erythematosus are the most important ones. There are several reports of localized alopecia after tick and flea bites and bee stings, but there is only one report of ant-induced alopecia in the literature. We report herein two cases of alopecia induced by ants of genus Phei...

متن کاملFunctional genetics and genomics in ants (Hymenoptera: Formicidae): The interplay of genes and social life
Ants are among the most remarkable and successful of animal taxa. The success of ants stems from their complex social systems, which originate, in part, from the genetic composition of individual society members. In this review, we evaluate progress in understanding how genetic information influences complex phenotypes in ants. We find that research on the structure of ant genomes has been stro...
متن کاملFunnel Control for Systems with Relative Degree Two
Tracking of reference signals yref(·) by the output y(·) of linear (as well as a considerably large class of nonlinear) single-input, single-output system is considered. The system is assumed to have strict relative degree two with (“weak”) stable zero dynamics. The control objective is tracking of the error e = y− yref and its derivative ė within two prespecified performance funnels, resp. Thi...
