AbstractDetailed studies on the immature stages of the sorghum head bugs, Eurystylus immaculatus Odhiambo and Creontiades pallidus Rambur, were carried out in the laboratory at Samanko, Mali, during November 1991 to March 1992, and January to April 1993, and in the field in October 1993. Eggs of both species were laid in maturing sorghum (Sorghum bicolor) grains. The egg incubation period was 4–7 days in E. immaculatus, and 5–7 days in C. pallidus. There were five nymphal instars in both species. The total nymphal period was 6–11 days in E. immaculatus and 8–14 days in C. pallidus. The durations of first, second, third, fourth and fifth nymphal instars were 1–3, 1–2, 1–2, 1–3 and 1–3 days, respectively, in E. immaculatus, and 1–3, 1–2, 1–3, 2–3 and 2–4 days, respectively, in C. pallidus. All the immature stages of E. immaculatus are described and sketched.

The aim of this work was to study biological aspects and the life cycle of Hylesia Metapyrrha in a laboratory. Laboratorial breeding was made at 25 ± 1 °C, 70 ± 10% UR and 14 hours of photophase, feeding the larvae with guava leaves (Psidium guayava L. - Myrtaceae). Time was evaluated on the days of all the development stages; morphometry was evaluated in millimeters and the pupa’s mass in grams. The eggs were disposed in groups and covered by urticating abdominal hair. The incubation period lasted 52 days. The larvae, with gregarious habits, presented background black coloration, yellowish scoli and two orange longitudinal lines above and below the spiracles, during the development which lasted an average period of 74.59 days and went through seven instars. The pre-pupa and the pupa stages lasted on average 8.82 and 50.56 days, respectively; the female pupae presented a duration, weight and size which was significantly bigger. The adult stage lasted on average 5.50 days with periods of pre, post and oviposition of 2.30, 1.90 and 1.00 days, respectively. This study broadens the knowledge of the immature stages, biological, morphological and behavioral aspects, until then restricted to the morphology and to registers of the occurrence of the adult forms.

AbstractObservations, measurements, dissections, and histological preparations were made daily of the eggs and larvae of Bathyplectes anurus (Thomson) while in their host, Hypera postica (Gyllenhal) (Coleoptera: Curculionidae). Observation of development began 24 h after oviposition and ended when parasite larvae emerged from their hosts.Parasite eggs doubled in length and width during their 3- to 4-day incubation period. Parasite larvae fed on hemolymph initially but later instars preferred the fat body and other tissues. B. anurus has five instars. From 18 to 21 days were required for the larvae to complete development and total development time was 21–25 days at 21 ± 1 °C.

The West-African variety of Sorghum bicolor leaf sheath (SBLS) Jobelyn® is a natural remedy, which has gained international recognition for its anti-anemic effect and energy boosting qualities in debilitating diseases. The widespread use of traditional medicine in the region usually confirms its safety, but not its efficacy or deep assessment of their pharmacological properties. The other major issue for herbal-based treatments is the lack of definite and complete information about the composition of the extracts.  Despite limitations, efforts have been made in isolation and characterisation of active compounds in this specie of sorghum showing various subclasses of flavonoids including apigeninidin, a stable 3-deoxyanthocyanidin and potential fungal growth inhibitor, which accounts for 84% of the total extract. Non-clinical in vitro and in vivo studies support previous indications that this variety of Sorghum bicolor possesses several biologically active compounds with potent antioxidant, anti-inflammatory, anti-aging and neuro-protective properties.  Clinical studies show that SBLS has the ability to boost hemoglobin concentrations in anemic conditions and most remarkably to increase CD4 count in HIV-positive patients. The multiple effects and high safety profiles of this extract may encourage its development as a therapeutic agent for the treatment of anemia, chronic inflammatory conditions or in the symptomatic management of HIV infections. This review describes the potential therapeutic aspects of SBLS extract and its potential benefits.

Blue Butterfly

The biology of the gram blue butterfly, Euchrysops cnejus (Fabricius) (Lycaenidae: Lapidoptera) and its relationship with the phenology of host plant cowpea, Vigna unguiculata L. (Fabaceae) were studied. Eggs were reared under the laboratory conditions at 28 ± 20C and 74 ± 3% RH. The incubation period of the eggs found to be 2.33 ± 0.51 days, larval developmental period 14.65 ± 0.51 days, pre-pupal period 0.30 ± 0.04 day and pupal period 5.66 ± 0.51 days. The species took 22.94 ± 0.55 days for development from egg to adult under the laboratory condition. The length of 1st, 2nd, 3rd and 4th instar larvae was 3.66 ± 0.40, 6.16 ± 0.51, 12.16 ± 0.51 and 15.33 ± 0.40 mm, respectively. The pre-pupal length was 9.16 ± 0.61 mm and the pupal length was 9.08 ± 0.37 mm. The host-plant occurs in the field from February to July. The butterfly appeared in March. The coincidence of the gram blue butterfly to its host-plant occurred between April and early July. The oviposition behaviour, incubation and immature stages were found to be profoundly related with host plant-phenological phases.Journal of Bangladesh Academy of Sciences, Vol. 39, No. 2, 241-248, 2015
