the biology of immature stages of s.sphegea and different techniques for their laboratory rearing has been studied during the past five years (1972-77). this fly is one of the 18 iranian species of snail-killing flies which is dominant in the focus area of schistosomiasis (khuzestan province) in the south-west of iran. the following procedures improved appreciably our laboratory rearin-technics...

Koutras has proposed some methods to construct reducible proper conformal Killing tensors and Killing tensors (which are, in general, irreducible) when a pair of orthogonal conformal Killing vectors exist in a given space. We give the completely general result demonstrating that this severe restriction of orthogonality is unnecessary. In addition we correct and extend some results concerning Ki...

Psychodini is redefined based on morphological characters and newly recognized homologies in the male genitalia. It is hypothesised that the ground-plan aedeagus of Psychodini consists of a symmetrical bipartite aedeagus flanked by paired, symmetrical parameres; which in many lineages have become asymmetrical via the differentiation of phallomeres and parameres and/or via reduction of one param...

Abcharis nom. nov. is established as a new substitute name for Notiocharis Eaton, 1913 (Diptera: Psychodidae: Psychodinae), which is a junior homonym of Notiocharis Gistel, 1856 (Coleoptera: Carabidae). The following new combinations are proposed: Abcharis assimilis (Quate & Quate, 1967) comb. nov.; A. dimorpha (Satchell, 1953) comb. nov.; A. femoralis (Quate, 1965) comb. nov.; A. filipinae (Qu...

Nonchemical quarantine treatments, using a combination of short-duration high temperatures under low oxygen, elevated carbon dioxide atmospheric environment were developed to control codling moth in sweet cherries, Prunus avium (L.). The two treatments developed are a chamber temperature of 45 degrees C for 45 min and a chamber temperature of 47 degreesC for 25 min under a 1% oxygen, 15% carbon...

the identification of different species of simuliidae, also called “black fly”, is based on particular structure of oral and terminal appendages of their larvae add also on the special morphology of adults and pupaes. because of their considerable flight range, the problem of finding their resting places, and also the difficulties of collecting the adult flies, breeding of this insect, in the l...

Adaptability of Fruit Flies (Bactrocera calumniata H.) to Cucurbitaceae Host Plants in the Highlands Bali. from family are one host plants for fruit flies. grow highlands and lowlands. One pests is Bactrocera calumniata. Symptoms attacked by B. having small holes that ooze fluid caused puncture ovipositor female flies after a long time becomes soft texture smells rotten. The research was conduc...
