Timing of spermatogenesis, chromosomes and sex determination of Amblyomma variegatum and A. Lepidum (Acari: Ixodidae)

Development of the testes and progress of spermatogenesis are dependent on time of attachment to the host. Testes of A. variegatum double in length and width, those of A. lepidum almost triple in length, double in width in the distal part and remain near the same size at the proximal part. Males of A. variegaturn, examined at 24 hr. intervals, show meiotic divisions after 120 hrs and elongated spermatids in seminal vesicles after 240 hrs. The latter process occurs in A. lepidum 48 hrs later. Both species have an XX/XO sex determination system; embryonic female tissue contains 22 chromosomes including 2 sex chromosomes, while male tissue contains only 21 chromosomes with one sex chromosome. Ten autosomal bivalents and one sex univalent are apparently present in males of both species. Surprisingly, 11 chromosomes were observed in embryonic tissue from a single batch of eggs ofA. variegatum .

1.6.4 Karyotyping techniques

World Crop Pests, 1996

Eriophyoid mites are hypothesized to be related to various superfamilies of Prostigmata, such as Tetranychoidea, Raphignathoidea, and Tydeioidea; therefore, it is interesting to determine the extent to which they show similar characteristics in karyotype. The study of eriophyoid chromosomes is also important for determining the constancy or diversity of haploid numbers throughout the subgroups of Eriophyoidea to assess polyploidy and to confirm arrhenotoky. This chapter discusses karyotyping techniques—Aceto-orcein temporary squash method and Smear method for permanent mounts—to study mitotic chromosomes in eriophyoid species. Aceto-orcein temporary squash method was originally developed for spider mites by Helle and Bolland and slightly modified for eriophyoid mites.

Pests of blossoms, buds, leaves, trunks, twigs and roots are briefly covered.

These include ten new pests of avocado and three of pecan. The pests of economic importance on avocado include Boarmia (Aseotis) selenaria (Schiff.) (Geometridae, Lepidoptera) and Heliothrips haemorrhoidalis (Bouch6) (Thrypidae, Thysanoptera). The pests of importance on pecans include Empoasca decedens (Paoli) (Jassidae, Homoptera), Zeuzera pyrina L. (Cossidae, Lepidoptera), and Monellia costalis (Fitch) (Aphididae, Homoptera).

The mortality caused by a 0.5% concentration (24,000 IU/cm 2) was significantly lower and presumably inadequate for practical application against this pest.

We found better detection of small increments in offbeat positions than on the beat, consistent with the influence of temporal prediction (Experiment 1). In addition, we found faster detection of large increments on the beat as opposed to offbeat (Experiment 1), and larger amplitude P1 responses on the beat as compared to offbeat, both in support of temporal attending (Experiment 2). As such, we showed that both temporal attending and temporal prediction shape our processing of metrical rhythm.

Effect of 20 Strains of Bacillus thuringiensis Berliner on Larvae of Boarmia selenaria Schiffermüller (Lepidoptera: Geometridae)

Isolate 30-11 (serovar 3a3b, kurstaki) proved to be 8% more effective than the standard HD-1-S-1980 (serovar 3a3b, kurstaki). This isolate was 13% more larvicidal to third instar larvae than the standard. Significant lower mortalities than the standard were obtained with the isolates: 400-1, 400-2, 400-3, 400-4, 400-8, 400-11, 400-12, 400-14, 30-2, 30-12, 30-13, 30-15, Ser. 17 and BL8a8c. Isolates 400-5, 400-6, 400-7, 400-9 and 400-10 were similar in larvicidal effectiveness to the standard.RésuméVingt souches de Bacillus thuringiensis Berliner qui appartiennent aux variétés: kenyae, kurstaki, aizawai et ostriniae, ont été testées pour leur activité contre le prémier stade de la larve de Boarmia selenaria Schiffermüller. La souche 30-11 (sérovar 3a3b, kurstaki) s’est avérée être 8% plus effective que le standard HD-1-S-1980 (sérovar 3a3b, kurstaki). Cette souche a été de 13% plus larvicide pour le troisième stade des larves que le standard. Les souches 400-1, 400-2, 400-3, 400-4, 400-8, 400-11, 400-12, 400-14, 30-2, 30-12, 30-13, 30-15, Ser.17 et BL8a8c prouvaient une baisse de mortalité obtenue par rapport au standard. L’effectivité comparable au standard étant de: 400-5, 400-6, 400-7, 400-9 et 400-10.

(near appendiculatus), R evertsi evertsi and R. simus, was observed and shown to be dependent on the length of time of attachment of the ticks to their host. The progress of spermatogenesis was studied by examinations at 24 hours intervals. In R. appendiculatus, meiosis appeared 96 hours after attachment of the tick to its host, elongated spermatids were observed in the testes after 120 hrs and in the seminal vesicles after 168 hours. In R. sp. (near appendiculatus), spermatogenesis occurred sooner after attachment and elongated spermatids were in the seminal vesicles after 120 hours. Meiotically dividing spermatocytes were observed in R. evertsi evertsi and R. simus 48 hours after attachment , while elongated spermatids were initially observed in the testes after 72 and 96 hours, respectively, and in the seminal vesicles after 120 hours. Ten autosomal bivalents and one sex univalent are present in males of the four species. Spermatogonia and embryonic tissue contained 20 autosomes and one large sex-chromosome in males and 20 autosomes and two sex-chromosomes in females. Thus sex is determined by an XX/X0 system.
