STUDIES ON PARASITES OF THE ORIENTAL FRUIT MOTH MACROCENTRUS ANCYLIVORUS In conjunction with production of Trichogramma for control of the Oriental fruit moth, the results of which have already been reported, field and laboratory work was begun in on the larval parasite, Mwrocen- trus ancylivorur Roh.

TRICHOGRAMMA Parasite breeding and liberation is a popular subject among fruit growers because of the apparent ease of control compared to the use of insecticides, but the difficulties in the way of successful application of the method are many and varied.

An account is given of further investigations on the parasites of Cydia (Laspeyresia) molesta, Busck, on peach in Ontario [cf. R.A.E., xix,etc.]. The marked increase in their numbers in was mainly responsible for a reduction in the damage effected by the pest.
Trichogramma minutum, Riley, was first found parasitizing eggs in the last week of June; this was its earliest appearance Author: Van Steenburgh. This bulletin concerns the work done in and on the subject of parasites of the oriental fruit moth. Headquarters were at Yokohama and the work has continued since then both in Japan and Chosen.
Results of these first 2 years show that the pest is the host of numerous species of parasites. Their individual incidence is here discussed at some by: 4.

In other host eggs, particularly in large eggs of certain species of Lepidoptera, 15 to 25 adults have been reared from one egg.

The parasite is most abundant in orchards where no broad-spectrum pesticides are used. Many studies have been conducted on agricultural systems to test the hypothesis that increased vegetational diversity fosters stability in the insect community. In a recent review of the available world literature, Andow () found that in a total of examples, the population densities of 66% of the monophagous herbivores studied decreased.
With Macrocentrus ancylivorus, a braconid parasite of the oriental fruit moth (Grapholitha molesta), a twelvefold resistance to DDT was produced after 19 generations of selection, but no significant increase in the resistance level was achieved up to the time the experiment was discontinued at generation 72 (Pielou and Glasser, ; Robertson.

Preface The critical phase of biological control work against weeds is the selection of species that will not harm other plants, or at least useful plants. All other considerations are subordinate, and a suitable species for introduction into a country against a weed is one that is safe to introduce, irrespective of its other characteristics.—J.

Description: The first issue of the Journal of The New York Entomological Society was published in March ofand it is still in publication. Authors deal with many aspects of entomology, but the theme is of a systematic or taxonomic nature including biology and ecology.
Editors have occasionally arranged special editions in which specific themes were followed and certain editions honored.Eggs, larvae, and pupae of the oriental fruit fly (Dacus dorsalis), melon fly (D. cucurbitae), and Mediterranean fruit fly (Ceratitis capitata) were exposed to Co⁶⁰ gamma rays.
Increasing dosages were required to prevent hatch as eggs became more mature except that eggs about 1/3 developed were more sensitive than younger ones.
