Bamboo pots used to collect mosquito larvae and brought into the laboratory after being exposed in a tropical rain forest for one year were subject to a series of drying and flooding with water for an additional year. Three species of mosquito larvae emerged. Haemagogus janthinomys (Dyar), Hg. leucocelaenus (Dyar and Shannon) and Aedes fulvithorax (Lutz). Eggs of Hg. janthinomys remained viable for a period of 31 weeks; Hg. leucocelaenus for 26 weeks and Aedes fulvithorax for five weeks. Peak emergence of Haemagogus janthinomys was in June, which is the beginning of the normal rainy season. Genetic and environmental conditions appear to govern this delayed hatching phenomenon.

Two dimensional polyacrylamide gel electrophoresis of proteins/polypeptides in the haemolymph of hibernating Culex pipiens pallens Coquillett, 1898 (Diptera : culicidae) caught from resting or overwintering places in the third ten days of September, second ten days of December, 1991 and first ten days of March, 1992 in Zhengzhou (34°43'N, 113° 39'E) indicated 133, 121 and 159 protein/polypeptides spots in the pre overwintering (preover), overwintering (over) and post overwintering (postover) adults respectively. The molecular weights (MW) of most of the spots varied from 13.9 to 67.0 KD, and the isoelectric points (pls) ranged between 5.52 and 7.34. The variant spots were 26 in the preover, 29 in over, and 42 postover adults. The variant rates were 19.55, 23.97 and 26.42 per cent, respectively. Comparison of the three hibernating stages showed that the variant rates were not significantly different (p>0.05). The total variant rates of the protein/polypeptides spots during the whole period of hibernation was 23.49 per cent. These results were compared with the physiology of hibernating mosquitoes.

The common mode of transmission of Pediculosis pubis is by physical contact with an infested individual or contaminated article. In this communication, the wearing of "sarong" and over crowding is speculated as one of the mode of nonsexual transmission that may encourage the crawling out of lice from an infested individual to gain access upon as uninfested one.

A total of 3200 copies of the first issue of The Annals of Medical Entomology was distributed all over the world. I received 189 congratulating messages; a little over fifty subscriptions and about 100 requests for complimentary copies; five journals published reviews, 23 papers for publication; 8 indexing and abstracting agencies offered for inclusion in their products; seven journals offered their publication on exchange basis, and, six new members joined the editorial board.

The medical entomologists needed a journal to express their views. The idea buzzed around in my head for several years. I have described the circumstances which encouraged the birth of this journal (Husainy, 1992a).

Ultimately the journal was born and a total of 3200 copies of the first issue was distributed all over the world. The picture that emerged was encouraging. I received 189 congratulating messages for launching the new journal. In addition, a little over fifty subscriptions and about 100 requests for complimentary copies also came by. Five journals published reviews on the Annals. Several scientists offered to review the papers submitted to the Annals. I received 23 papers for publication and a few more indexing and abstracting agencies informed me to cover the Annals in their products. Seven journals offered their publication on exchange basis with the Annals.

Publishers of seven periodicals desired exchange of the Annals with their publications. All journals and publications that I receive are deposited in the Literature Museum (Husainy, 1992b). I, therefore, welcome exchange of more journals.

A great majority of the authors wanted a reduction in the page charges also. The journal costs about $1000.00 per issue to produce and just pays its own way. Everybody knows about the roaring costs of publication and postages. I pestered many authorities for financial assistance but their response was that there was no money for such a project. Thus for a new journal without any patronage like the Annals, it seems impossible to cut down the page charges but for pulling more papers, the page charges is reduced to $20.00 per printed page from this issue.

Since the distribution of the first issue, many booksellers solicited trade inquiries and per cent given. Some of them expected 40 per cent discount. All of us, of course, work for nothing. This is a non profit journal. Its main aim is to serve the medical entomologists in the early publication of their papers and to raise a strong reference centre in the form of Literature Museum. I request all the subscribers to send their subscriptions directly to the Annals.

The success of this issue means that I have to go on with the project. I request all concerned to bear with me the delay in the publication of this issue. The arrears of issues will be published soon. I also hope that this issue of the Annals will be welcomed by the readers. The global distribution (Husainy, 1992a) of specimen copies will again be repeated for this issue but this time complimentary copies will not be mailed to those who received the inaugural issue. I am confident that there will be a regular influx of more papers for publication.

Husainy (1992a) described the methodology of the project Literature Museum in details. Since then there was a good flow of reprints and publications in the Literature Museum. We received the following journals on exchange basis : (1) Zoological Research (Vol.13, Nos. 1, 2, 3, a quarterly published by Kunming Institute of Zoology, Kunming, P. R. of China. This always contains articles on insects of medical importance. (2) Uttar Pradesh Journal of Zoology (Vol. No. 11, Nos. 1, 2; Vol. No. 12, Nos. 1, 2 a half yearly published by the Uttar Pradesh Zoological Society, Muzaffarnagar 251001, India); (3) Annali del Museo Civico di Storia Naturale Giacomo Doria (Vol No. LXXXVIII - 1990-91, A monograph of world Cerylonidae (Coleoptera - Cucujoidea. Pt. I - Introduction and higher classification); (4) Folia Entomologica Mexicana (Vol. No. 83, 84, 1991 - 92 published by Sociedad Mexicana de Entomologica, Xalapa, Veracruz, Mexico); (5) Essays of an Information Scientist (Vol. No. 10, 11, 12, 13 & 14 published by ISI Press, Philadelphia, U.S.A.); (6) Fragmenta Entomologica (Vol No. XXIII, XXIV, XXIII - Supplemento, Dipartimento di Biologia Animale - e -Dell Uomo, La Sapienza, Rome, Italy); (7) Tropical Disease Bulletin (Vol. No. 87, No.1, Abstract 1 - 312, Jan., 1990, published by the Bureau of Hygiene & Tropical Disease, London, U. K.); (8) Revista de la Sociedad Entomologica Argentina (1991), published by Sociedad Entomologica Argentina, La Plata). Many thanks to these publishers for enriching the Literature Museum. We welcome receiving more journals on exchange basis.

We also received reprints from several scientists, some of them as follows; the numbers in the parenthesis after the name of a scientist indicate the number of reprints sent by him. Dr. S. Sulaiman(21); Dr. T. G. T. Jaensen(16); Dr. Ralph A Bram(7); Dr. A. E. Terterjan(1); Dr. A. Ralph Barr(35); Dr. J. D. Wright(1); Dr. Janice H. Yen(1); Dr. V. P. Sharma(4); Misc.(6). We are grateful to these contributors. Every reprint counts, for it adds to the strength of this Literature Museum.

Husainy (1992b) stated that the Literature Museum is an informal cooperative effort of the authors, government and private agencies, institutions, scientific societies, libraries and other such organizations of the world. We hope that the influx of reprints will surely increase day by day making it soon a useful reference centre for medical entomologists and specialists.
