“…In general, the epithelium of the spermatheca of insects is classified in three basic types, according to the location of secretory cells [17] . In the first type, found in Periplaneta americana, secretory cells are distributed throughout the entire wall of the reservoir [13] , as also observed in our study for A. s. piriventris and the ant species A. l. balzani, A. balzani and A. landolti examined by Ortiz and CamargoMathias (personal communication). In the second type, gland cells are restricted to a particular region of the epithelium, as reported for Aedes aegypty [18] and for A. s. sexdens examined in our study.…”

The insect's spermatheca store the spermatozoa from the time of copulation until the fertilization of the eggs and consists of a sac, usually associated to glands. The ant species Atta laevigata, Atta sexdens sexdens, Atta sexdens piriventris, Acromyrmex coronatus and Cyphomyrmex muelleri are considered pests, as they cause economics losses to several crops. The spermatheca of these species were examined by scanning electron microscopy, histological and histochemical techniques. Their morphology resembled that of a bilobular pouch partially jointed in the central portion. In A. coronatus and C. muelleri it is flatter in shape than those of other species. The external spermathecal gland, groups of secretory cells, was located at the joining point of the two spermathecal lobes of the reservoir. This was observed in A. laevigata, A. s. sexdens and A. coronatus, like a group of cells, while in C. muelleri, like filaments. An external associated gland was not observed in A. s. piriventris, instead secretory cells were arranged in a simple prismatic epithelium internally lining the spermathecal lumen. This epithelium was also observed in A. s. sexdens, although it was restricted to the joining point of the spermathecal lobes. The presence of an internal secretory epithelium in A. s. piriventris and A. s. sexdens suggests that their physiology for the maintenance of spermatozoa in viable conditions for egg fertilization might differ from A. laevigata, A. coronatus and C. muelleri, in which only an external spermathecal gland was observed.

Morphological and ultrastructural organization of the spermatheca of some Tettigoniidae (Insecta, Orthoptera)

A morphological and ultrastructural study of the spermatheca of some species of Orthoptera Tettigoniidae was carried out to understand the role of this female organ in the reproductive biology because no literature exists about it in this insect group. In all the examined species, the spermatheca is of ectodermal origin and is composed of a seminal receptacle, mainly involved in the collection and storage of the spermatozoa, and of a spermathecal duct. In both these organs, the epithelium of the wall is made up of two different cell types: cuticle-forming cells, underlying the cuticular intima, and gland cells. Both of these cell types have secretory features that differ among the species and also within the same species, in relation to the tracts examined. In particular, the ultrastructure of the distal tract of the spermathecal duct indicates a more marked secretory activity than in the other tracts of the duct. This activity is often accompanied by ultrastructural aspects, suggesting a lysis activity in both the epithelium and the upper cuticle. Based on these findings, it is hypothesized that the seminal receptacle and the spermathecal duct have different functional roles, despite having a similar general structural organization.

Males from bilateral crosses between T riatom a sórdida anã INTRODU CTIONPerlowagora-Szumlewicz (?) has reported m ale sterility induced through interspecific hybridization of Triatom inae. Males from unilateral and reciprocai crosses were un able to give offspring, as shown by backcrosses between hybrid males and parental íem ales, while hybrid females backcrossed to p aren tal males proved fertile; eggs developed into vigorous adults. Furthermore, adult progeny from the subsequent backcrosses behaved like the progeny from the first backcross, th a t is to say, th a t males were again unable to engender off spring from p aren tal females. The Author suggested th a t the prim ary component of the induced sterility was a failure on the p a rt of the hybrid male to tran sfer sperm successfuly during m ating. Holt & North (5) in studies conducted w ith cabbage loopers had encountered sim ilar problems with the transm ission of sperm by irradiated males.Evidence presented by Dawey d) dem onstrated th a t in Rhodnius prolixus, like in m any other insects (2,4,5), m igration of spermatozoa to th e sperm atecae is a result of contraction in the female duets set up by a milky granular secretion, originated in one of the four lobes present in the S u p p o r te d i n p a r t b y C o n s e lh o N a c io n a l d e P e s q u is a s a n d W o rld H e a lt h O r g a n iz itio n . * D e p a r ta m e n to d e B io lo g ia G e ra l, I n s t i t u t o d e C iê n c ia s B io ló g ic a s , U n iv e rs id a d e F e d e r a l d e M in a s G e r a is , B e lo H o riz o n te , M G ., B ra s il. ** L a b o r a tó r io d e B io lo g ia e C o n tr o le d e V e to re s d a D o e n ç a d e C h a g a s , I n s t i t u t o d e E n d e m ia s R u ra is , F u n d a ç ã o O sw a ld o C ru z , J a c a r e p a g u á , R io d e J a n e ir o , B ra s il. =*** F e llo w , C e n t r o d e P e s q u is a s d e P r o d u to s N a tu r a is , I n s t i t u t o d e C iê n c ia s B io m é d ic a s , U n iv e rs id a d e F e d e r a l d o R io d e J a n e ir o , R J .
