Saccharine sorghum has been analyzed as a supplementary prime matter for ethanol production, especially during the sugarcane off-season period. However, it has proven to be highly susceptible to insect attacks during the cultivation cycle. The fall armyworm should be emphasized due to its voracity and high damage capacity enhanced by feeding-caused decrease in photosynthetic area. Current analysis studies the biology and determines the nutritional indexes of Spodoptera frugiperda in saccharine sorghum. Cultivars of saccharine sorghum BRS 506, BRS 509 and BRS 511were evaluated. Duration and survival of the egg, caterpillar, pre-pupal and pupal phases were determined, coupled to weight of pupae and caterpillar, life span, fecundity and pre-egg laying period. Although S. frugiperda completed its life cycle on cultivars BRS 506 and BRS 511, egg-laying and egg feasibility rates were low, whereas insects did not lay eggs on cultivar BRS 509. There was no significant difference in feeding intake by S. frugiperda among these three sorghum cultivars. Results suggest that saccharine sorghum is not a suitable host for S. frugiperda. Biological data reveal that the three saccharine sorghum cultivars are recommended for the grain production system since the number of specimens of the next generation is low or null.

Among different fruit piercing moths, the genus Othreis are the most harmful, causing widespread damage to pomegranate, citrus and mango fruits causing fruit fall in tropical and subtropical countries. The present communication deals with the study on the biology of  Othreis materna (L) from egg to adult’s death which was carried out  at room temperature of the laboratory  to investigate the delicate and vulnerable stages of its life cycle. The life cycle of the moth was completed within 45-61 days, with an average 55.03 days in case of male and within 47-63 days with an average 57.07±4.92 in case of female. Eggs hatching started at night or early in the morning and duration of hatching was 2.72 days. The eggs measured were about 0.95 to 0.03 mm in diameter. The freshly emerged first instar larvae were light yellowish coloured and translucent. The first instar larvae were very active after hatching and they moved 4 to 6 feet for searching the food. The larvae were fed with the leaves of Tinospora cordifolia (Giloy or Guduchi). The total larval duration in days from first, second, third, fourth and fifth instar varied from 2.12±0.01, 1.81±0.05, 2.87±0.02, 3.90±0.11, 4.74±0.38 in days respectively and total larval period was 15.44±0.57. Pupae were dark brown in colour and total pupation period was of 13.81±0.12 days and total adult duration for male and female was 23.08±0.70 and 25.20±0.66 days respectively. The adult of O. materna was bright orange in colour and of medium size. The male was small than the female. This is first study of this type from Marathwada, which will help to trace the vulnerable and delicate stage of the life cycle of this O. materna.

Two new synonyms are established: Bryotypella = Paranyctycia Hreblay & L. Ronkay, 1998, syn. n. and Bryotypella = Parabole Hreblay & L. Ronkay, 1998, syn. n. Six new combinations are established: Bryotypella minima (Hreblay & L. Ronkay, 1999), comb. n., Bryotypella miraculosa (Hreblay, Peregovits & L. Ronkay, 1999), comb. n., Bryotypella orbiculosa (Hreblay & L. Ronkay, 1998), comb. n., Bryotypella rubiculosa (Hreblay & Ronkay, 1999), comb. n., Bryotypella medionigra (Hreblay & Ronkay, 1998), comb. n. and Bryotypella rectilinea (Hreblay & L. Ronkay, 1998), comb. n. The check-lists of the genera Bryotypella and Charanyctycia are provided. Adults, male and female genitalia of the new and the related taxa are illustrated.

Feldmann (1970: 249), quoting the results of Hustede (1960), who had shown that Bryopsis halymeniae Berthold (1882: 497) was the gametophyte of a Derbesia sp.[1], pointed out that this species could  not belong to the genus Bryopsis differing from it in chloroplasts with no pyrenoids and gametes without a stigma. On that basis, as well as because of its peculiar life cycle, he stated that Bryopsis halymeniae should  be considered the type of a new genus: Bryopsidella. Even though Feldmann (1970) did not explicitely propose the new combination Bryopsidella halymeniae, such a binomial was reported by Gallardo et al. (1993: 412, note 60) and by Boudouresque & Per-ret-Boudoure-sque (1987: 83).[1]A more complete paper showing that Derbesia neglecta and Bryopsis halymeniae are phases of one species, was later published by Hustede (1964).

AbstractThere are five caterpillar instars in the life cycle of Spodoptera exempta (Walk.) when they feed upon star grass, Cynodon dactylon (L.) Pers., maize, Zea mais L. and Kikuyu grass, Pennisetum clandestinum Chiov. at 25–30°C. When the temperature is 18°C, however, there was an additional instar in the cycle. Similarly extra instars are formed on Guinea grass, Panicum maximum Jacq., Setaria plicatilis (Hochst.) Hack, and a sedge, Cyperus maranguensis K. Schm. even when the temperature appears to be sufficiently high for normal development. Occasionally the additional sixth instar is also too small to pupate, in which case a seventh instar is formed. It appears that caterpillars on nutritionally inadequate host plants or those at low temperatures are being partially starved and must continue moulting until the appropriate size is attained or exceeded. Measurements of the head capsule widths or distances between the frontal clypeal setae suggest that only individuals reaching or exceeding a species specific threshold size pupate. Extra moults appear to be an adaptation to environmental fluctuations obtaining within the range of occurrence of S. exempta.
