“…Presumably it either resulted from the conversion of bound fats to a free condition or was synthesized in the cells from carbohydrates and/or proteins. Munson and Yeager (6) found that in P. eridania fat appeared and continued to be found in the haemocytes as glycogen disappeared from them. They also noted that haemocytes of larval stages contained fat inclusions if the larvae ingested sufficient fat.…”

“…Storage of different nutrients, like carbohydrate, lipid and amino acids by the hemocytes and their role in maintaining the normal nutrient balance during different stress conditions are well documented (Munson and Yeager, 1944;Arnold, 1952Arnold, , 1970. The alterations in the number of circulating hemocytes, maintaining a relationship with the alteration of nutrient levels in the haemolymph, demonstrates the role of stored food materials in the hemocytes (perhaps by releasing them into the haemolymph) to balance the nutrient level in the haemolymph during periods of acute energy need, since these nutrients were reported to serve as an immediate fuel source during exercise in the cricket S. monstrosus (Islam and Roy, 1983).…”

physiological functions, as previously mentioned. 2.1. Variation in Number and Types of Circulating Hemocytes: It is interesting to give some historical information about the hemocyte classification and characterization. Hollande (1911) firstly attempted to classify and categorize the insect hemocytes after the earlier research works, particularly those of Cuenot (1897) and Kollmann (1908). Then, Wigglesworth (1939) followed each of Hollande's categories. Yeager (1945) identified ten hemocyte classes containing 32 different types in the Southern armyworm Prodenia eridania. Some years later, Jones (1962) reduced this number to nine distinct cell types, and his generalizing work earned a special place in the history of hemocytes, since his classification was the basis used by most researchers thereafter. The same author described eight hemocyte types in insects: PRs, PLs, GRs, Cystocytes (CCs), OEs, ADs, Podocytes (POs), and Vermiform cells (VRs). With this classification, this author established a system to give an order to more than 70 names for hemocyte types used by earlier investigators. Later, Price and Ratcliffe (1974) examined the hemocytes of 15 representative insect orders and distinguished six different types distributed in those orders: PRs, PLs, GRs, spherulocytes (SPs), CCs and OEs; however, CCs were absent in Lepidoptera. Using phase contrast microscopy, Sharma and Dutta (1979) recorded the presence of ten categories of hemocytes: PRs, PLs, GRs, CCs, COs, SPs, ADs, OEs, POs and VRs in the grasshoppers Chrotogonus trachypterus and Acrida exaltata. Although, Gupta (1979) recognized seven main types of haemocytes in various insect orders, namely PRs, PLs, GRs, SPs, ADs, OEs and Coagulocytes (CGs), while Gupta (1994) merged the category CGs with that of GRs. Although Brehelin and Zachary (1986) proposed a new system with nine hemocyte types, the classified categories of haemocytes ranged, generally, from four to seven (Gupta, 1979) or between three and nine (Wigglesworth, 1959; Arnold, 1972, 1974). However, some authors described three to eight hemocyte types in several insect orders by means of the transmission electron microscopy (TEM)(Ratcliffe and Rowley, 1979; Al-Khalifa and Siddiqui, 1985). As reported in the available literature, the main types of hemocytes are PRs, GRs, PLs, SPs and OEs. These hemocyte types have been described in insect species of diverse orders,

“…Dennoch kann man aus der Mannigfaltigkeit der beschriebenen Zelltypen zwei relativ gut abgegrenzte Blutzellgruppen herausstellen, die unter den verschiedenen Blutbildern zwar weit verbreitet sind, jedoch mit zahlenmai3ig meist nur geringem Anteil, namlich 1. sehr kleine Zellen mit verhaltnismai3ig groi3em Kern, der von einer schmalen, stark basophilen Cytoplasmaschickt umgeben wird. Diese Zellen kommen vor allem in den jungen Larvenstadien (BOGOJAVLENSKIJ 1932, YEAGER 1945, ARNOLD 1952 Cytoplasma-Vakuolen (ERMIN 1939, YEAGER und MUNSON 1941, MUNSON und YEAGER 1944, WIGGLESWORTH 1955a, 1956 unter den verschiedensten natiirlichen und experimentellen Bedingungen andern konnen.…”
