Abstract A study on the flowering biology and pollen production of the common laburnum (Laburnum anagyroides Med.) was conducted under the conditions of Lublin during the period 2004 - 2006. The flowering of this species began in the second 10-day period of May and lasted for 2.5 - 4 weeks. The flowers of common laburnum are borne in showy golden-yellow pendulous racemes. They develop successively, starting from the base and moving to the tip of an inflorescence. During the growing season, one shrub produces 800 to 3200 racemes, with 14 to 35 flowers in a single raceme. On average, the flowering duration for a raceme was 12.8 days and 8.7 days for a single flower. Throughout the study years, the shrubs proved to be most attractive in the third 10-day period of May when they reached full bloom. The average weight of pollen produced was 6.08 mg per 10 flowers of Laburnum anagyroides, 14.02 mg per raceme, and 26.0 g per shrub. Pollen grains reached average dimensions of 24.01 μm × 24.26 μm.

Bombus Cooleyi, n. sp.— ♀. Length, 16–17 mm. Integument black; clothing black, yellowish white, pale ochreous yellow and rusty yellow. Head, seen from in front, about as wide as long. Malar space abont one-sixth the length of eye. Third segment of antenna one-half longer than fourth, and scarcely longer than fifth. Face thickly clothed with pale yellowish-white hair, on the sides mixed with black. Vertex clothed with yellowish-white hair, which is fringed in front with black. Cheeks clothed with brownish-black, sometimes slightly mixed with whitish, hair. Clypeus shining, sparsely punctured, labrum fringed on free edge with rusty yellorv hair. Clothing of thorax above and on sides yellowish white, mixed with black in front of insertion of wings. A broad patch of black berween the wings surrounds the smooth, polished mesothoracic disc and extends back in a point over the middle of metathorax. On each side of metathorax is a tuft of yellowish white bair.

Macrophya flavicoxae, Nort.Head light brown, almost orange on the vertex, a little dot at occiput, eye in a black spot; width, 1.8 mm. Body greenish white, not shining, a dusky black dorsal stripe and a very distinct velvet-black lateral one, broken into two square patches situated on the third and fifth annulets, connected by smoky shadings. The spots are broken up posteriorly and absent on joint 13. Dorsal band greenish black. Segments neatly annulate, feet on joints 6–12 and 13; anal plates immaculate. Towards the end of the stage the segments are faintly orange banded in the middle (on second and third annulets), the anal flap broadly orange.

This parasite approaches Neumann's Haematopinus (Polyplax) maniculatus, but is immediately recognised by the truncate proboscis, by the “ olecranon process ” of the hind pair of legs, and by the remarkable “ comb ” which terminates the abdomen of the ♀. Perhaps a new genus should be made to receive it.Linear, abdomen about four times the length of the head and thorax together. Head very broad, proboscis truncate, its lateral margins diverging to as far as the antennae, behind which the head enlarges at right angles. Post-antennal area rectangular, broad ; the occipital margin a little convex. At each posterior angle a long hair ; on the under surface, at about the level of the antennae, two short bristles, one on each side. Antennae of five segments, the first being thick and stout, the second narrower and the longest, the third short, and the fourth broad with a sharp prominence at the post-axial distal corner. Adjoining the prominence a small circular sense-organ which crosses the joint and occupies part of the base of the terminal segment. The latter is longer than the third or fourth, and has several spines at the end. Thorax broader than the head and broader behind than in front. A large flattened spheroidal spiracle at each lateral margin.

This spccies is extlemely similar to C. maxillosus, and its American representative. The following circumstances principally distinguish them. The anterior angles of the prothorax in C. maxillosus are thinly cloathed with shortish black hairs; in C. villosus, these hairs are cinereous, longer, mole numerous, and cover a larger portion of the angle; in the former, the band of the elytra is whiter and wider than in the latter; in the former also the back of the abdomen, especially the third and fourth segments, is mottled with cinereous hairs; in the latter the second and third have each a cinereous band interupted in the middle; again the four first ventral segments in C. maxillosus are thickly covered with decumbent cinereous hairs, with each a lateral black spot on both sides, while in C. villosus

Abstract. Herlinda S, Octariati N, Suwandi S, Hasbi. 2020. Exploring entomopathogenic fungi from South Sumatra (Indonesia) soil and their pathogenicity against a new invasive maize pest, Spodoptera frugiperda. Biodiversitas 21: 2955-2965. Fall armyworm (Spodoptera frugiperda) is a new invasive maize pest in Indonesia that can cause maize yield losses of 18 million tons/year. To overcome the pest, local-specific entomopathogenic fungi are needed. This study aimed to explore entomopathogenic fungi from soil in South Sumatra and to determine their pathogenicity against S. frugiperda larvae. The fungi exploration was carried out in the lowlands and highlands of South Sumatra and the pathogenicity of obtained isolates were tested against the third instar larvae. The entomopathogenic fungi found were Metarhizium spp. and were successfully isolated as many as 14 isolates. All of the isolates were pathogenic to S. frugiperda larvae (70.67−78.67% mortality), the most pathogenic caused 78.67% mortality and significantly suppressed the emergence of adults up to 81.2%. Unhealthy larvae had a dry, shrunken, shrinking, odorless body, and its integument was covered in mycelia and conidia like yellowish-white powdery mixed with dark green. The unhealthy pupae and adults were in the abnormal and malformation shape. The abnormal pupae were shorter in size, bent, the to-be wings got wrinkled, and darker color, while the unhealthy adults had folded wings and were unable to fly. The two most pathogenic isolates were found from the lowland (PirOI) and highland (CasPsPGA) soil of South Sumatra. In conclusion, both of these isolates had the potential to be developed into local-specific mycoinsecticides to control pest insects in the highlands and/or lowlands in Indonesia.
