Abstract: the objective of this study was to investigate the natural occurrence of t. alecto, an egg parasitoid of diatraea spp. in sugar cane in the state of alagoas. the eggs of d. flavipennella and d. saccharalis presented 47.9% and 30.0% with characteristics of parasitism, and viabilities of 92.4% and 89.9%, respectively. the presence of this natural enemy suggests a potential for natural regulation of diatraea spp.

Abstract: this work studied the parasitism capacity of telenomus remus nixon (hymenoptera: scelionidae) on spodoptera frugiperda (smith) (hymenoptera: scelionidae) eggs at 15, 20, 25, 28, 31, and 35°c, aiming to use this natural enemy in biological control programs in crops where s. frugiperda was considered pest. the parasitism during the first 24 h was 60.90, 81.65, 121.05, 117.55 and 108.55 parasited eggs per female from egg masses of approximately 150 eggs, at 15, 20, 25, 28 and 31°c, respectively. females of t. remus reached parasitism higher than 80% at 15, 20, 25, 28 and 31oc at 5, 27, 8, 2, and 2 days, respectively. at 35oc, there was no parasitism. the highest parasitism rates occurred at 20, 25, 28 and 31°c. t. remus female longevity varied from 15.7 to 7.7 days from 15 to 31°c. the highest tested temperature (35°c) was inappropriate for t. remus development. at that temperature, female longevity was greatly reduced (1.7±0.02) and egg viability was null. all t. remus survival curves were of type i, which showed an increase in mortality rate with time.
Functional response of Telenomus remus Nixon(Hymenoptera, Scelionidae) to Spodoptera frugiperda (J. E. Smith) (Lepidoptera, Noctuidae) eggs: effect of female age

Abstract: functional response of telenomus remus nixon (hymenoptera, scelionidae) to spodoptera frugiperda (j. e. smith) (lepidoptera, noctuidae) eggs: effect of female age. functional response of 24-h and 48-h-old telenomus remus adults was studied on spodoptera frugiperda eggs. the study was carried out in climatic chamber regulated at 25 ± 1°c, 70 ± 10% rh and 12:12h (l: d). females of t. remus were honey fed and individualized in glass vials along with 25, 50, 75, 100, 150, 200, 250 or 300 eggs of s. frugiperda for 24 h. complete randomized design with ten replications was adopted. the parameters evaluated to construct the functional response curve were daily average parasitism, searching rate and oviposition time. it was observed that the higher the egg density, the higher the parasitism for 24-h and 48-h-old females although there was a tendency of parasitism stabilization at 150-egg density. the results showed a type ii functional response curve for both 24-h and 48-h-old female.

BIOTROPIA : the Southeast Asian Journal of Tropical Biology , 2002,
Abstract: Random amplified polymorphic DNA (RAPD) amplified by the polymerase chain reaction (PCR) was used to determine the differences of four Telenomus species and five populations of T. rowani from several locations in Java. Amplification of genomic DNA by using primer P2 (Amersham Pharmacia Biotech) indicated that each Telenomus species had a unique set of RAPD bands. Two bands which characterized the genus are estimated to be 300 and 430 bp. Each species had three specific bright bands except T. dignoides which only had two specific bright bands. However, no bands are unique to any of the five populations of T. rowani and all of the bands are less than 500 base-pair. Cluster analysis using UPGMA (Unweighed Pair Group Method With Arithmatic Mean) showed that the four Telenomus species consist of two groups, T. rowani and T. remus in one cluster and T. dignus with T. dignoides belonging to another cluster

Abstract: the parasitism of telenomus podisi ashmead, on some pentatomid pests of soybean [glycine max (l.) merrill] was studied. the tests were conducted during soybean crop (1996/97) on two areas, cultivated with br-48 and br-37 (area 1 and 2, respectively), at embrapa soja, in londrina, pr. euschistus heros (fabricius), piezodorus guildinii (westwood) and nezara viridula (linnaeus) were the most abundant species on this crop. the highest populational density occurred at the end of the crop cycle (5.3, 3.3, 3.6 - area 1 and 5.2, 14.5, 7.5 stink bugs / 2 m - area 2, respectively). on both areas, the parasitoid t. podisi had better interaction, with the population of e. heros, with increasing parasitism on the area 1, reaching 100% in the end of the cycle, and showing above 80% during all sample period on area 2. the parasitism obtained on eggs of e. heros, in cages with isolate population of this insect, was statistically similar, when compared with eggs of the same pentatomid in cages with mixed population containing the three species (31.7 ± 7.51 and 20.1 ± 6.67, respectively). p. guildinii and n. viridula, however, had consistently more parasitism in cages with mixed population.
