Eggs And Larvae

AbstractDetails of a method of mass rearing eggs and larvae of the cabbage root maggot, Hylemya brassicae (Bouché) for bioassay and of continuous propagation of all stages of the pest are described. The technique was equally suitable for rearing the onion maggot H. antiqua (Meig.), the seed corn maggot H. calicruraliturata (Rond.) and the carrot rust fly, Psila rosa (L.). Under the conditions described, 2000-2500 eggs or first-instar larvae of H. brassicae were obtained from 50-60 female flies in 24 hours, or 1000-1200 mature larvae or pupae were reared from eggs produced by 25 female flies in approximately 20 days.

AbstractA technique for mass rearing the carrot weevil, Listronotus oregonensis (LeConte), is described. Adults were provided with carrot roots for food and oviposition sites. Larvae developed directly in these roots. Different temperature regimens for larval rearing were tested and best results were obtained using 21 °C for the first 2 weeks of larval development and 27 °C thereafter. Photoperiod was maintained at 16 h and relative humidity at 70%. Under these conditions, 97.6% of adults emerged in 39–42 days.

Close Relationship

Field observations on C. cilicrura and C. trichodactyla have shown that in Britain the larvae feed on beans, peas, cabbages, kale, cauliflowers, leeks, onions, cucumbers and lettuce. The importance of C. cilicrura as a pest of beans in spring was well known; its attack on cucumbers was suspected but had not been verified; but the infestation of leeks and brassicas in summer and spring cabbages in autumn had not hitherto been recorded in Britain. An association of larvae of C. cilicrura with rotting vegetation has not so far been established.Descriptions of adult and larval stages are given. Diagrams are given to illustrate specific differences between larvae of C. cilicrura and those of the onion fly, Hylemyia antiqua.Field observations have shown that C. cilicrura is on the wing from March to October and there is some evidence of slight activity during the winter months. There are 3–4 generations a year, and peak periods of fly activity occur during mid-April to mid-May, late June to early July, and in fine weather throughout the period August to October.Larvae have been taken throughout the period May to December. Peak periods of larval activity occur from mid-May to early June on beans, peas, cucumbers and cruciferous crops, during July on leeks and cruciferous crops, and during September to November on spring cabbages.The close relationship between cultural practice in south Worcestershire and the occurrence of high populations of C. cilicrura is discussed.A summary of control measures devised by other investigators is given. Modifications of cultural practice that would be likely to reduce attack by C. cilicrura are suggested. Results of preliminary trials with naphthalene and DDT emulsion are given.

Electron Microscopes

In recent years, with electron microscopes coming into wider use, their installation environments do not necessarily give their performance full play. Their environmental conditions include air-conditioners, magnetic fields, and vibrations. We report a jointly developed entirely new vibration isolator which is effective against the vibrations transmitted from the floor.Conventionally, large-sized vibration isolators which need the digging of a pit have been used. These vibration isolators, however, are large present problems of installation and maintenance because of their large-size.Thus, we intended to make a vibration isolator which1) eliminates the need for changing the installation room2) eliminates the need of maintenance and3) are compact in size and easily installable.
