AbstractThe biology of Telenomus chloropus Thomson was studied on eggs of Nezara viridula (L.) which had been reared on the stink bug resistant soybean, Glycine max (L.) Merrill, genotype PI 171444 and the susceptible cultivar Davis. Time of development of T. chtoropus from egg to adult emergence was not significantly different in eggs oviposited by N. viridula reared on either Davis or PI 171444. However, successful emergence of T. chloropus from host eggs was significantly lower for parasitoids that developed in eggs from N. viridula reared on PI 171444. Longevity of adult T. chloropus was not significantly different between females that were allowed or denied oviposition regardless of the genotype fed the host. Total fecundity of T. chloropus reared from eggs of N. viridula fed PI 171444 was one-half that of parasitoids from the Davis treatment. Although ovipositional patterns over the lifetime of parasitoids from the 2 treatments were similar, the mean number of progeny produced per day was significantly greater in the Davis treatment. Also, the ovipositional period of parasitoids from the PI 171444 treatment was shorter than for parasitoids from the Davis treatment.

Abstract Background The phorid fly Megaselia scalaris (Loew) (Diptera: Phoridae) is an omnivorous species, capable of exploring a large variety of environments and ecological niches. It is known as an important detritivore species with maggots feeding on a variety of food of both animal and plant origin. Results The present study reports M. scalaris as an endoparasitoid attacking colonies of the southern green stink bug Nezara viridula (L.) for the first time. This case of parasitism was observed inside rearing cages of N. viridula at  the Plant Protection Research Institute, Dokki, Egypt in August 2020. We firstly identified adult individuals of M. scalaris which were found moving erratically within the cages using relevant identification keys. To verify that N. viridula individuals are parasitized by the same parasitoid and they are not infected with other parasitoids, some of the parasitized bugs were transferred to a separate cage at the same laboratory conditions and the developmental stages of the dipteran parasitoid were observed until the adult emergence. Conclusion The present investigation revealed that M. scalaris could be included to the recorded parasitoid species of N. viridula, and further studies should be carried out to assess the efficacy of this fly as a biocontrol agent.

Laboratory studies were conducted on mating, ovipositional rhythm, and fecundity of the southern green stink bug, Nezara viridula (L.) fed on immature fruits of privet, Ligustrum lucidum Thunb. and soybean, Glycine max (L.) Merrill. A greater number of pairs were observed mating on privet (27 to 37 %) than on soybean (22 to 23 %). The preoviposition period was significantly shorter when females fed on privet (15.5 days) than when they fed on soybean (23.9 days). The intervals of time between the first four ovipositions, and between the 1st and the 4th oviposition were shorter on privet than on soybean (range of 1.9 to 3.3 days less on the former food). Greater percentage of females N. viridula oviposited and showed greater fecundity on privet than on soybean. On privet, the oviposition rhythm peaked at days 11 and 17; however, no peaks on oviposition were observed on soybean.

<em>Aenasius arizonensis</em> (Girault) ( = <em>Aenasius bambawalei</em> Hayat) (Hymenoptera: Encyrtidae), a solitary endoparasitoid of <em>Phenacoccus solenopsis</em> Tinsley, is a major invasive pest in several cotton growing countries around the globe. It has been recorded as an effective natural enemy of <em>P. solenopsis</em>. The biological characteristics of parasitoid were studied on <em>P. solenopsis</em> under laboratory conditions. The mean duration of development of <em>A. arizonensis</em> from oviposition to mummy formation was 5.9 ± 0.31 days for both male and female, while from mummy formation to adult emergence was 5.9 ± 0.31 and 7.3 ± 0.3 for male and female, respectively. The mean developmental period of male and female was 12.2 ± 0.33 and 14.2 ± 0.37 days, respectively. Males were short lived (16.3 ± 1.41 days) as compared to females (26.2 ± 1.72 days). Female started ovipositing on the day of emergence. The mean pre-oviposion, oviposition and post-oviposition periods were &lt;1, 23.1 ± 1.66 and 3.1 ± 0.55 days, respectively. Mean daily and total fecundity in terms of number of parasitized host per female was 4.24 ± 0.2 and 100.5 ± 11.57, respectively. Sex ratio was skewed towards female and recorded as 1:2. Maximum percentage of parasitization occurred in adult host stage i.e. 90% followed by 3<sup>rd</sup>, 2<sup>nd</sup>, and 1<sup>st</sup> instar nymph with 73.33%, 33.33% and 0 per cent, respectively. Among the three nymphal stages 3rd instar nymph was the most suitable stage for mass multiplication of parasitoid. Its successful utilization in mealybug management can be optimized by multiplying at this stage of host in the laboratory and thereafter inoculative release into the field. This report provides a detailed diagnostic description of <em>A. arizonensis</em> with illustration to facilitate easy identification &amp; morphological differences between male &amp; female along with the morphometric measurements of pupa &amp; mummy.

Parasitoid Development

The objective of this work was to study the biology and parasitic potential of Doryctobracon areolatus on larvae of Anastrepha fraterculus. The egg-adult period, the sex ratio, the longevity, the pupal viability, and the parasitism rate of D. areolatus were determined in laboratory, using A. fraterculus as host. The parasitoid development from oviposition to adult emergence required 25.00±1.70 days, the sex ratio was 0.62±0.09, and the mean longevity was 16.36±3.62 days for males and 10.24±1.71 days for females. The mean parasitism rate was 53.50±8.93%, varying from 41.60 to 68.60%, which shows the potential of this parasitoid for biological control of A. fraterculus.

Even though resistance is the most promising tactic for root-knot nematode management on soybean (Glycine max), virulent biotypes may occur and be selected on specific resistant plant genotypes. In the present study, reproduction rate of Meloidogyne arenaria race 1 increased after four sequences of continuous culture of the parasite on resistant soybean genotypes.
