REPORTS OF DR. E. H. ANDERSON. [41] 



Put up a number of chrysalids in wire-gauze box No. 5, and also in glass jar No. 6. 



Octoher 18. — One motb out in No. 5 box. 



October 19.— Rain. Temperature, 56° F. 



Octoher 20.— Two moths out in box No. 4 (not Aletia) ; 2 out in No. 5; 7 out in No. 

 2, and 1 parasite. Temperature 52° F., 8 a. m. Put up 10 cbrysalids in glass box 

 No. 7, top and sides glass, bottom wood. This intended as a vivarium for observing 

 copulation and procreation. 6 p. m., temperature 60° F. All the above chrysalids 

 were found in leaves of Convolvulus, cotton stalks bare. 



Octoher 21.— One moth out in box No. 7. Temperature, 50° F., 7 a. m. Put five eggs 

 on glass on box No. 1. Put up 61 chrysalids in wooden box with wire gauze top No. 

 8, soil on bottom, chrysalids laid loosely on top of soil. Temperature, 60° F. Rain. 



Octoher 22. — Four moths out in No. 5 and 4 in No. 7. Temperature, 66° F., 8 p. m. 



Octoher 23. — Rain. 



Octoher 24.— Temperature, 68° F., 8 a. m. ; 1 moth out in No. 4 ; 5 moths out in No. 

 5; 6 moths out in No. 7 ; 8 moths out in No. 2. 



October 2b. — Temperature, 48° F., 8 a.m. 



October 26. — Light frost; 7 moths out in No. 7. 



Octoher 27. — One dead moth in box No. 4. Temperature, 60° F., a.m. Visited a 

 field wbere the worms had stripped southern portion, leaving a strip in northern part 

 in full foliage ; this strip skirted east and west by^ forest. Found a few chrysalids, 

 no larvai, eggs, or moths. These chrysalids were of the fifth brood. Raiuy day. 



Octoher 28. — Visited a field with a small area left unstripped. Found a few larva? 

 full grown, black color predominating, still feeding but languid in appearance. No 

 fresh eggs found. Brought in a number of chrysalids, many of which have not com- 

 pleted their transformation. An inspection indicates clearly that the case is formed 

 from the larval integuments, the body forming its own sarcophagus. Rain. Temper- 

 ature, 64° F. 



Octoher 29. — Transferred 7 chrysalids from box No. 1 to No. 3. Placed 21 chrysalids, 

 brought in on the 27th, in box No. 1. Fifteen moths ottt in No. 5 ; 13 out in No. 1. 

 Temperature, 64° F., 8 a.m. 



Octoher 31. — Forty moths out in No. 5 ; 3 out in No. 6 ; 8 moths out in No. 7. Tem- 

 perature 58° F. Cloudy. Revisited a field visited on the 10th and found but little 

 of the second growth of cotton left. Found a few larvae large and small of the fifth 

 brood, and also a number of fresh eggs on top leaves, as many as eight to the leaf, and, 

 in one instance, twin eggs twice on the same leaf near together. These I have placed 

 in a glass bottle, cutting the leaf into small sections, with the egg as deposited. 

 Aphis and ants quite abundant. Only found ants among colonies of Aphides. Noticed 

 that the leaves from which the lice had sucked all the juice of the parenchyma, and 

 which were about to fail, were covered with lice. What becomes of the lice when they 

 reach the ground ? 



November 1. — Visited two fields where there is yet considerable foliage ; searched for 

 larva-, and eggs of Heliothisarmigera, but found none, and no indications of their pres- 

 ence, though green and young bolls were abundant. Brought in a few eggs and chrys- 

 alids of Aletia. Temperature, 68° F. Clear. 



Novejuher 2. — Sixty moths out in No. 5. These were put up on the 15th, and have 

 developed more rapidly than others. Moths in No. 7 (vivarium) depositing eggs. 

 Temperature 64° F., 3 a. m.; weather clear. As the weather becomes cooler, have 

 noticed the tendency of the moths to crowd together. 



November 3. — Visited a field of fresh land cotton where I found northeast corner not 

 eaten by the worm, the rest of the field bare. The leaves nibbled here and there and 

 fresh and full of chrysalids ; no fresh eggs. Found a few full-grown larvae feeding. 

 Searched diligently for Heliothis and examined a number of young and grown bolls, 

 but found no eggs or perforations in the bolls or any sign whatever. No lice or ants 

 were observed on this cotton. Temperature 43° F., 7 a. m. Brought in a number of 

 chrysalids and a lot of larvae. 



In regard to Heliothis I may remark that, probably owing to drought, they have done 

 no damage to cotton, and my inability to find them is owing to the fact of its desertion 

 of cotton for other vegetation more succulent. I am at this date gathering green to- 

 matoes and find a large proportion perforated by Heliothis and many ruined, so that in 

 several bushels I lose a fifth or sixth, say about 20 per cent. My opinion is that 

 we have here but four broods of Heliothis annually, first in corn, second and third in 

 cotton, and last in garden and other vegetation. 



November 'i. — Temperature 34° F., 7 a.«m. On visiting my garden, examined a cot- 

 ton stalk in full foliage at the end of a tomato bed and found Aletia eggs on many 

 of the top leaves and found two on outside of involucre. On one leaf found as many 

 as eight eggs, two side by side in close proximity. Found also a young boll which 

 had been perforated by a Boll Worm, but found no larva or egg on the^talk. Found 

 two HeliotMs armigera on tomato, one-half buried in the fruit; these I sent you. 

 The frost has been a nipping one. 



Found moths in box No. 5 crowded together and many in a torpid condition that
