Abstract
"NEST FOR AND METHOD OF MANAGING MEGACHILE ROTUNDATA"
ABSTRACT OF THE DISCLOSURE
A nest for Megachile Rotundata bees includes a group of blind tunnels specifically designed to present bees with tunnels as near as possible to natural to suit their instinctive nesting habits. The nest is designed as a single-use unit which simplifies protection and collection of young while fumigating and sterilizing to avoid disease possibly present on retrievable progeny. The nest described herein has characteristics which will permit control of fungus, mold and infestation by predators, but is still durable for the period of activity of laying down of young by adults during pollination and during the breeding period. The nest is configurated of paper tubes having seams adhered together by water-soluble adhesive. When the nest is immersed in a water bath after progeny have been developed in the tubes, the tubes open, releasing the progeny to float in the bath where the progeny can be conveniently harvested. The water bath may contain pesticides or other substances to control fungus, mold and predators. After the progeny have been released into the bath from the nest, the nest is dried and burned to destroy any disease organisms remaining therein.

Description
BACKGROUND OF TflE INV:f3NTION
This invention rela~es to improvements and r~finements in nests used for trapping, domestication, husbandry and mana~ement of "Megachile Rotundata", commonly known as leaf cutter bees by persons involved in growing Lucerne ~Alf Alfa" and like Leguminosae pasture for seed, and by other practicing pollination services using such bees, or the like, as pollinators.
It is an established fact that seed set is considerably increased in the aforesaid crops by the introduction of Megachile Rotundata bees for pollination when such crops are at a suitable blooming stage. In addition, these bees are able to increase their numbers from generation to generation.
Leaf cutter bees generally are solitary bees, but Megachile Rotundata are known to be gregarious and are not averse to living amongst their own kind with each female mating only once. She alone constructs cigar~ e shaped cells inside blind tunnels, or preexisting holes of a suitable bore within which the ova for procreation are deposited. In this description, Megachile Rotundata, for simplicity, will be referred to as leaf cutter bees.
Research also indicates that by providing artificial or manmade tunnels, leaf cutter bees can be kept within a selected area to both pollinate and regenerate their kind during which activity one cell, including the depositing of ova, .is completed at least once per day, inside the blind tunnels commencing at the furthest point from the opening and progressing along in sequence to the front of said tunnels, such cells being oriented end-to-end in a horizontal plane.
In order to recover the progeny and permit increasing bee numbers, it is necessary to retrieve from such tunnels each and every live cell, as well as to protect the livestock from infestation by pathogens and attack by pests and predators during nesting and during the active adult li~e cycle, which averages six weeks per adult.
Lea cutter bees are entirely different biologically,

Lea cutter bees are entirely different biologically,
2 ,.
physically and actively from the ~amiliar honey bees r,~hich originate from a single fertilized queen whose progeny swarm and live in a hive, manufacturing from their own glands wax and honey from which they sustain their own kind and from which both products are recovered by the owner of such hive or hives.
Honey bees, "Apis mellifera~', are e~uipped with substantial stingers and at times tend to aggressivenes.s, but the leaf cutter bee has no effective stingers and therefore no defense against predators or pests. They do not produce honey or wax.
The purpose of tAis invention is to provide a suitable num~er of tunnels within the minimum possible space. Since the discovery of man's ability to trap and domesticate along with managing this bee, a wide variety of artificial forms of nesting tunnels have been conceived. Approaches lnclude:
drilled wooden blocks with backing sheets, grooved boards which have been either bolted or clamped together to form blind tunnels, extruded tunnels in polystyrene-type materials, and also like materials with half-circle grooves again clamped together.
All of the aforesaid materials present problems for retrieval of the progeny. In addition, there is the problem of the considerable area required to provide, say five thousand, tunnels from solid materials. All of the heretofore approaches were costly to produce and supply to owners of bees.
In addition to the high cost and the design problems of tunnels, users were and are currently compelled to remove and recover the young manually or by additional machinery or equipment, and thence attempt to sterili~e such nest materials to prevent residual pathogens from infesting next generation bees.
It has been proven from research and practice that such action is costly and inherently ineffective.
A completely waxed paper conglomerate of blind tunnels was developed in 1979, which development is the subject of Australian Patent No. 541,427, the named Inventor in which is Frederick Arthur Norman. It has been ound and ascertained from further research that the nest is not effective and presents added .~j ~0 r3 t~
restriction on recovery of the young as well as yenerating high temperatures in the solid materials because of the inability of air to reach and circulate around cells contained in the tunnels.
This is the case because wa~ed tunnels do not permit natural moisture in leaf-clipping-formed cells to be absorbed by the tunnel material.
SUMMARY OF ~HE INVENTION
It is a purpose o~ this invention and an improvement to earlier known leaf cutter bees' nests to provide a light, effective, low cost group of blind tunnels which comprise say five thousand such tunnels parallel with one another, concentrated in the least possible area, with an acceptable internal diameter to suit the biology of the bee and its activities within said tunnel whilst building c811s from leaf clippings therein.
Broadly stated, the invention is a nest for Megachile Rotundata being a corrugated packing board tray formed by a base with all ~our sides upstanding defining an open internal space having a visible face upon which is placed a water or liquid resistant adhesive o~ such quality and quantity that when a plurality of open ended paper tubes are placed in the vertical plane thereon to tightly pack the space encompassed by sides, blind tunnels are formed and secured in situ by g~ass like hard non-soluble barrier when set.
~ nother broad aspect of the invention is a method of managing Megachile Rotundata comprising the steps of:
configuring a nest of a plurality of paper tubes arranged in an array of blind tunnels wherein each is readily openable upon being soaked in water, each tunnel providing a cell in which the progeny o~ the Megachile Rotundata are contained;
harvesting the progeny by soaking the nest in a bath of water to open the individual cells so as to release the progeny therefrom and floating the ~ 3 ~
progeny on the surface of the bath so that the progeny can be collected for 3ubsequent nestiny;
drying the nest after ~oaking, and destroyirlg the nest -to destroy any disease existiny therein.
BRIEF DESCRIPTION OF THE DRAWINGS

DE~AIL D D~SCRIPTION
It has heen established from research that greater control of bee morality along with improved health of livestock can be attained by practicing loose-aell storage during the diapause - period and that the destruction by burning of all previously used nesting materials destroys any pathogens or fungi which may have been present at collection of young.
It has also been established from research that in order to reduce compost action by leaf clippings forming the cells, it is essential for as much air as is possible to circulate around blind tunnels 11 in a nest 10 with a material used being able to absorb air and dis9ipate moi9ture rapidly. Hence the structure kj~'3'~' or collection of tunnels 11 in situ Figure 2 with spaces 12 between the tunnels is used.
Recent tests by the inventor have indicated that the tunnels 11 should be configured as paper tubes of a preferred paper material with an inside bore 13 to suit a nesting bee.
This arrangement provides the required rate of moisture absorption and heat dissipation from leaf clippings over a given period during nesting activities of leaf cutter bees as depicted in Figure 4.
The aforesaid paper tubes 11 also have ideal ambient thermal properties when grouped within a given space. In accordance with a suggested embodiment, five thousand tubes are mounted in an area of 270 square centimeters contained within a corrugated packing board tray which has a base with four sides upstanding in a manner to constrain all tunnels within the perimeter. In order to permit release of the tubes, such fixing is designed to allow access to the base of the tray after the tunnels have been used and filled with cells of leaf cutter bees, as is correlated -to Figures l and 3.
When laying down their progeny~ leaf cutter bees need protection from pests and predators. All facets of the nest herein described can be physically protected, except the front opening giving access to the bees which, however, can be readily viewed by the owner. The activity of bees discourages entry from that area. Thus it will be seen that the rear and sides of said nests are vulnsrable to intrusion by predators and pests. Hence it becomes essential to present an impregnable barrier (14 Figure ~) to such end of the tubes forming the blind tunnels to discourage predators which seek to consume the laid contents of the cells within the tunnels 11.
~ he aforesaid barrier can be achieved by af~ixing the tubes 11 to the rear wall of nest 10, as is shown in Figure 8, by applying a suitable adhesive which will then retain the tubes, now blind tunnels, and which when set has a glass-like surface and is completely insoluble when wet and/or immersed in water or ~"¢~,.'.1 jtj~
such like liquid. Pigure 3 indicates ~he use o~ such material.
The sides of the nest ga:Ln protection by being suitably sited within a preferred area i.n the ~ield.
Referring now to Figures 5 and 6, the tubes or tunnels 11 can be made in several ways. One method is by extrusion crimping and sealing the edges of a strip of paper with an adhesive which is water-soluble. Such an extrusion should be made from a particular weight of paper. A ~urther method of manufacture is to spirally laminate another particular weight of paper to give an identical weight of paper to that which is extruded. The spirally laminated paper is again sealed using an adhesive of quick-drying capacity, but highly water-soluble. In Figure 5A, a closed spiral seam 15 is shown before soaking. During soaking of the nest 10, the seam 15 opens up as is shown in Figure 5B.
Figure 6A shows a tube 11 with a closed straight seam 16. Upon soaking the nest 10, the straight seam 16 opens, as is shown in Figure 6B.
The production of the aforesaid materials into nests for use in pollination of crop, regeneration and retrieval of progeny is achieved by using suitably devised packing methods to secure tubes 11 firmly within the bounds of the tray base when the upstanding sides are locked in position.
When placing the aforesaid within suitable or preferred shelter in the field or area to be pollinated, it is advantageous and o~ assistance to bees, which it has been established can recognize colors and geometric forms, to have such ~orms and recognised colors stencilled over the face of the nests 10. This aids bees in orienting themselves to their selected tunnels on return to the nest. A typical stencil 17 with geometric patterns 18 is shown in Figure 7.
It will therefore be seen form the foregoing that a light, durable nest 10, when suitably sited in accord with management techniques now being practiced, can ~e made available at low cost to bee owners and operators. The ~ollowing method of collection and fumigation or sterilization from disease, simultaneously, .~ 7 i5~7 presents immense cost savings and advantages.
To collect or harvest the progeny con-tained within blind tunnels, the nest or nests are removed from shelters or protection in the field and are taken to a preferred site at which a suitable container of water, to which is added a selected fumigant or sterilizing agent, is provided.
The owner or operator of bees and nests merely releases a lock on each corner of the upstanding sides of the nest 10, lowers the nest while oriented in a level plane, and, with the back uppermost, immerses the nest face down in the water which then permits the adhesive holding the tubes in circular form to release. The blind end 14 of the nest lO is affixed to the back of the tray. The tunnels 11 wi-ll then unravel and release progeny contained therein which progeny float on the water. Any pests, predators or cadavers will sink or drown. Figures 5B and 6B both depict conditions of tunnels after immersion.
All live cells can then be collected, dried and stored in suitable containers within a cool storage area for hibernation, whilst the residual nesting material is placed aside to dry, ready for burning.
While it will be seen that considerable detail and description of the nests along with husbandry practices is described herein, it is to be realized variations aan be made in materials used and methods of assembly, and these variations are intended to be considered within the scope of the present invention.
