Agriculture is dependent on insect pollination, yet in areas of intensive production agriculture, there is often a decline in plant and insect diversity. As native habitats and plants are replaced, often only the weeds or unwanted vegetation persist. This study compared insect diversity on mango, Mangifera indica, a tropical fruit tree dependent on insect pollination, when weeds …

Predicting the next toy fads with AI. By Janelle Shane On December 14, 2021 - 2 min read. Few could have predicted that the must-have toy of 1998 would be an owl-like bilingual hamster doll with infrared sensors, or that in 1975 kids would be begging their parents for a toy that is literally a single rock in a cardboard box.

Published: 1979 Abstract The structure of the maxillipeds and mouthparts is generally similar in C. taeniatus, C. virescens, P. squamosus and D. setifer, but differences exist in the setation of these limbs and in the form of the crista dentata of the third maxilliped endopods.

Life Cycle and Biology. Colonies of A. nomas are rare during the winter (December–February in central Florida) and are concentrated in live oak (Quercus iana Mill.) hammocks and stands of cabbage palms (Sabal palmetto [Walter]) where they probably are best sheltered from killing frosts. During this time, colonies are composed primarily of adults with a few late instar nymphs.

Classically, Hemiptera is comprised of two suborders: Homoptera and Heteroptera. Homoptera includes Cicadomorpha, Fulgoromorpha and Sternorrhyncha. However, according to previous molecular phylogenetic studies based on 18S rDNA, Fulgoromorpha has a closer relationship to Heteroptera than to other hemipterans, leaving Homoptera as …

Mollusks – Chordata. Can be divided into 2 groups, based on the structure of their embryos. Larva – immature stage that is independent & can feed itself. Also called schizocoelomates – form a coelom by splitting the mesoderm. Also called entercoelomate – form a coelom by out-pocketing of the primitive gut.

In contrast to the mouthparts and gastric mill, the pyloric filters are rather uniform in all decapods. The midgut tube is a straight tube, which, when compared to the hindgut, is relatively long in some decapods like shrimps and lobsters but short in crayfish and crabs ( Bell and Lightner, 1988 ; Icely and Nott, 1992 ; Factor, 1995 ; Vogt, 2002 ).

Archipsocus nomas Gurney is a communal web-spinning barklouse. During some years they make extensive silken webs that often cover the trunks and branches of trees in the southeastern U.S. The webs are believed to protect the barklice from predators. The webs are unsightly, but neither the barklice nor the webs cause any harm to the trees.
